[02:36] <arrrghhh> hello, can someone school me on LVM?
[02:37] <arrrghhh> i have a media/file server whatever... and it's outta space again.  it seems LVM is what i should've done in the first place, but didn't.
[02:37] <arrrghhh> i assume i need to pillage and start over on all hard disks that aren't the boot disk... correct?
[02:37] <arrrghhh> hrm... perhaps i can start with the new disks in LVM, move the data to them and get the old disks into the LVM... this is all so new to me.
[02:38] <arrrghhh> i'm used to boring old hard disks and partitions.
[02:53] <twb> arrrghhh: you cannot in-place convert to LVM
[02:53] <arrrghhh> twb, i have to completely reinstall ubuntu?
[02:54] <qman__> LVM isn't the only way to expand your system
[02:54] <qman__> it's just one
[02:54] <qman__> what setup do you have now?
[02:54] <arrrghhh> i'm not thinking i can save the data.  i was thinking start new hdd's on LVM, move data to new LVM, then move old hdd's to LVM
[02:54] <arrrghhh> nothing
[02:54] <arrrghhh> just hard drives lol
[02:54] <arrrghhh> hard drives and mount points
[02:54] <qman__> yes, but how are they configured?
[02:54] <arrrghhh> not sure what you mean
[02:54] <arrrghhh> no RAID
[02:54] <arrrghhh> no LVM
[02:54] <qman__> so a filesystem on each drive
[02:54] <arrrghhh> yes
[02:55] <qman__> yeah, that's not a good arrangement
[02:55] <arrrghhh> most disks have one partition encompassing the entire disk
[02:55] <arrrghhh> other than the main hdd with the installation on it
[02:55] <arrrghhh> no, it's not very scalable.
[02:55] <qman__> hard drives are inherently unreliable, and that doesn't even give you a performance advantage
[02:55] <arrrghhh> yea, i realize that...
[02:56] <qman__> total replacement is the only real way to accomplish it
[02:56] <arrrghhh> ...
[02:56] <qman__> create an array, copy files over
[02:56] <arrrghhh> i have to shuffle my data around somehow
[02:56] <arrrghhh> i gotta back everything up
[02:56] <qman__> you could add disks to it as you go but it would take a very long time
[02:56] <arrrghhh> so you recommend RAID...?
[02:57] <qman__> yes
[02:57] <arrrghhh> and only RAID?
[02:57] <qman__> I have nothing positive or negative to say about using LVM
[02:57] <qman__> I don't use it myself
[02:57] <arrrghhh> hrm
[02:57] <arrrghhh> well i've never used any of these advanced features
[02:57] <arrrghhh> like i said, i'm used to just having hard drives and partitions
[02:58] <qman__> I've expanded arrays a few times without LVM, no trouble
[02:58] <qman__> using ext3
[02:59] <qman__> LVM would allow you to expand without modifying the original, though
[02:59] <arrrghhh> hum
[02:59] <qman__> you could in theory create your current array, put data on it, then create a second array, and expand your LVM to both arrays
[02:59] <arrrghhh> i just want something more easily scalable
[02:59] <arrrghhh> this current setup was fine when i only had a couple of hard drives
[03:00] <arrrghhh> but it's becoming unmanageable.
[03:00] <qman__> it's fine until you lose data
[03:00] <arrrghhh> i know
[03:00] <arrrghhh> which i want to take care of this before i do
[03:00] <arrrghhh> plus, i'm running out of disk space :D
[03:00] <qman__> which will happen sooner or later, just a matter of luck
[03:01] <arrrghhh> my one concern with RAID is i have a lot of different sized disks
[03:01] <qman__> I definitely recommend RAID, or an alternative like ZFS
[03:01] <arrrghhh> i didn't think i could RAID a bunch of different sized disks...
[03:01] <arrrghhh> i didn't think ZFS was supported...?
[03:01] <arrrghhh> or at least not stable.
[03:01] <qman__> it's getting there, but it's only really stable on solaris kernels
[03:01] <arrrghhh> yea
[03:01] <arrrghhh> not exactly feasible for me...
[03:02] <qman__> if you can't get new disks
[03:02] <qman__> try to match up the sizes as evenly as possible
[03:02] <twb> If you have md RAID 1, you could create a new degraded array on one half, move the data to it, then add the other disk into the array
[03:02] <arrrghhh> hrm
[03:02] <arrrghhh> well i am going to get new disks
[03:03] <arrrghhh> but i'd like to still use the old ones
[03:03] <twb> Oh well, that's much easier
[03:03] <qman__> an array can only be as large as the greatest common denominator
[03:03] <arrrghhh> indeed
[03:03] <twb> qman__: ITYM lowest
[03:03] <qman__> use the old disks for backups
[03:03] <arrrghhh> and i have a couple of disks that don't match in size
[03:03] <arrrghhh> and a couple that do
[03:03] <arrrghhh> 1 500gb, 1 200gb, 2 1tb's.  looking to get a 2tb or maybe even 2x2tb's...
[03:04] <_GoRDoN__> It's possible to use different sized disks with software raid but smallest disk would define the size you would be able to use from each disk
[03:04] <arrrghhh> yea, i don't want to go that route
[03:04] <arrrghhh> i know i'm taking a risk with my data, but i can't really afford that many hdd's right now.
[03:04] <_GoRDoN__> of course you can make another array from those leftovers =)
[03:05] <arrrghhh> and lose 300gb on my 500 gb drive?  lol no thanks.
[03:05] <qman__> with what you have, I'd recommend either getting all new for your array, or getting more 1TB disks
[03:05] <qman__> and ditch the smaller ones
[03:05] <qman__> use them for something else
[03:05] <arrrghhh> ugh
[03:05] <arrrghhh> yea, if i wanted to do this server right
[03:05] <arrrghhh> i really need to upheave it...
[03:06] <qman__> a few other things
[03:06] <qman__> don't buy 'green' drives
[03:06] <arrrghhh> i usually get WD Caviar Black's.
[03:06] <qman__> raiding those is a disaster waiting to happen
[03:06] <qman__> and make sure you set up smartd
[03:07] <arrrghhh> i have that setup
[03:07] <qman__> preempting failure is critical
[03:07] <arrrghhh> yea
[03:07] <qman__> performance wise
[03:08] <qman__> if you just want a big storage bin, one large array is good
[03:08] <arrrghhh> ugh, the space i'm going to lose is the hardest to swallow
[03:08] <qman__> in my case, I also run torrents on it, and I think that's caused some undue fragmentation
[03:08] <arrrghhh> well i wanted to segment the bin's
[03:08] <qman__> so, if I were to set up new, I'd separate that to a different disk or array
[03:08] <arrrghhh> i was thinking one big RAID array and splitting it up logically with LVM
[03:09] <qman__> I wouldn't do that just for organization, only if performance is an issue
[03:09] <qman__> use a good directory structure for organizing
[03:09] <qman__> it's the most scalable and will have the least problems
[03:09] <arrrghhh> well yea but my directory structure has outgrown a single disk
[03:10] <arrrghhh> so all the media i buy is backed up to the server, and we watch it thru a UPNP media streamer, so no fumbling with discs
[03:10] <qman__> the less barriers you have, the easier it will be to maintain
[03:10] <arrrghhh> i have a hdd for tv shows, and a hdd for movies
[03:11] <arrrghhh> they're both getting past the point of being able for all  my tv shows to fit on one hdd
[03:11] <qman__> I have directories for each
[03:11] <qman__> on the root of my array
[03:11] <arrrghhh> and all your disks in one big array?
[03:11] <qman__> yes
[03:11] <qman__> well, actually not the root
[03:11] <qman__> I have my array mounted on /home
[03:12] <qman__> and everyone's home folder is there, plus two
[03:12] <arrrghhh> yea i'd probably put it on /media
[03:12] <qman__> one 'public' for the data
[03:12] <arrrghhh> but that's neither here nor there
[03:12] <qman__> and one 'torrentflux', for the obvious
[03:12] <qman__> inside public there are folders for all the things, movies, TV, games, music, etc
[03:12] <arrrghhh> i guess i need to read up on RAID arrays
[03:12] <qman__> and I set up my file shares based on it
[03:13] <arrrghhh> one thing that i'm not sure how to do, is backup all the data i have and get the existing disks into the array
[03:13] <qman__> if I were to do it again, I'd put torrentflux on a separate disk or array, because of the performance hit on a raid 6
[03:13] <arrrghhh> assuming i trash the 200/500
[03:13] <arrrghhh> and just go with 1t's
[03:13] <qman__> it'd take some shifting, but if you buy three new ones you can do it
[03:13] <arrrghhh> i didn't think i could do RAID6 with just 2 disks is my dilemma...
[03:13] <arrrghhh> ah
[03:14] <arrrghhh> if i buy three new ones, i see how that would work
[03:14] <arrrghhh> not sure the space would be there... hum.
[03:14] <qman__> raid 5 them, copy one 1TB to it, add that disk, copy the other 1TB, add it, then copy the smaller ones
[03:15] <arrrghhh> i need to read up on the different levels
[03:15] <arrrghhh> RAID6 you can survive up to 2 disk failures
[03:15] <arrrghhh> and 5 is just 1 failure, correct?
[03:15] <qman__> 1 is mirror, 5 is striping with one parity disk, 6 is striping with two parity disks
[03:15] <qman__> yes
[03:16] <arrrghhh> yea i need to re-read all that crap on striping and parity
[03:16] <qman__> I'm running 12 disks, 11 in raid 6 and a hot spare
[03:16] <arrrghhh> 12 zomg
[03:16] <arrrghhh> i need a bigger server :P
[03:16] <arrrghhh> i don't even know how many my case can handle... let alone the mobo.
[03:17] <qman__> I got a new SATA3 controller, it can handle the full 6GB/s on all channels
[03:17] <_GoRDoN__> qman__: Are you using some kind of multiplier or something?
[03:17] <qman__> my disks are SATA2 but preparing for the future
[03:17] <qman__> the controller has 8 channels, plus the onboard has 6 + 2
[03:18] <qman__> unfortunately the onboard controller doesn't like my samsung disks, so I'm still using one of my old PCI controllers for now
[03:18] <arrrghhh> qman__, you do software RAID tho, right?  mdadm or whatever?
[03:18] <qman__> but when I upgrade, it'll be ready
[03:18] <qman__> yes
[03:18] <arrrghhh> k
[03:19] <qman__> next upgrade I'm going to get one of those norco rackmounts with 24 hot swap bays
[03:19] <qman__> but that's a while off
[03:21] <arrrghhh> yea i thought my server build would last me a few years
[03:21] <arrrghhh> already outgrew it
[03:21] <arrrghhh> been slowly adding to it, seems now I need to spend some serious cash to get it up to snuff.
[03:22] <qman__> mine started as a budget thing, originally with 6 500GB disks, second hand CPU and power supply, emachines case, etc
[03:23] <qman__> outgrew that, added two more disks and a real case
[03:23] <qman__> then my array crashed, so I replaced it with 8 1TBs
[03:23] <qman__> then the motherboard quit so I got a real core
[03:23] <qman__> and recently the disks I used went on sale, so I got four more
[03:24] <arrrghhh> ha
[03:24] <_GoRDoN__> =)
[03:25] <qman__> but I'm having some bad performance issues
[03:25] <qman__> I can only get about 30-35MB/s writes
[03:25] <qman__> raid 6 is a real bear
[03:25] <qman__> and I think I've got fragmentation issues
[03:25] <arrrghhh> yea, mine's still inbetween the budget and crazy rig stage.
[03:26] <arrrghhh> i've got a fairly good processor, but RAM specs are low, and disk arrangement is obviously not ideal :P
[03:27] <qman__> the next full rebuild will use ZFS or btrfs, or something like them
[03:28] <arrrghhh> yea, ZFS sounds promising
[03:28] <arrrghhh> and from what i read, ext is really just waiting for btrfs to replace it lol
[03:28] <qman__> still using the 4GB quantum fireball for the system partition
[03:29] <twb> ZFS has the cuddle of death
[03:29] <twb> wait for btrfs
[03:29] <arrrghhh> cuddle of death?
[03:29] <twb> CDDL
[03:29] <qman__> if that drive ever dies, I'll move to a flash disk of some kind, probably CF
[03:29] <arrrghhh> oh
[03:29] <twb> SATA SSDs are vastly better than CFs, and not much dearer
[03:30] <twb> We ran CF for a while, it was a major PITA
[03:30] <twb> e.g. apt-get update would take ten minutes
[03:30] <qman__> yeah
[03:30] <qman__> I've got one in my T23
[03:31] <twb> Also, IME you're better off going RAID1 instead of RAID5/6, provided you can live without that extra disk worth of storage
[03:32] <qman__> 5 isn't too bad but 6 is a huge performance hog
[03:32] <_GoRDoN__> clear
[03:33] <_GoRDoN__> wrong window...
[03:36] <twb> qman__: even with 5 you have to fuck about aligning stripes and such
[03:36] <twb> qman__: I usually don't have time to get that stuff right; it's easier to just say "You get 2TB, not 6TB.  Suck it up, princess."
[03:36] <arrrghhh> lol
[03:37] <arrrghhh> i don't really want to lose any disk space, but that's the price you gotta pay for security
[03:38] <twb> s/security/reliability/
[03:38] <twb> Or rather: minimizing hassle
[03:39] <arrrghhh> so a bunch of raid1 array's minimize hassle?
[03:39] <_GoRDoN__> btw does the raid controller matter that much if you are using software raid as long it's supported?
[03:39] <arrrghhh> _GoRDoN__, the point of doing software RAID is you don't need a RAID controller...
[03:40] <twb> Er, *a* RAID1
[03:40] <twb> _GoRDoN__: if you're using md raid, there is no "raid controller"
[03:40] <twb> _GoRDoN__: you just use any old AHCI SATA controller
[03:41] <qman__> with software raid, the only thing that matters is throughput
[03:41] <qman__> as long as the controller can keep up with all the disks you attach, it's good
[03:41] <lifeless> and your UPS
[03:41] <twb> lifeless: don't talk to me about managers buying hardware raid cards without BBUs :-/
[03:41] <_GoRDoN__> eh.. meant sata controller
[03:41] <qman__> also, in case you were wondering what I managed to cram 13 hard drives into, it's this: http://www.newegg.com/Product/Product.aspx?Item=N82E16811119152
[03:42] <lifeless> twb: :)
[03:42] <twb> qman__: *hello, SPOF*
[03:42] <twb> I've shipped a few Centurions in my time; they're alright for their price.
[03:43] <qman__> 3 4-in-3 adapters, and the last one's in the floppy holder, resting behind the front panel
[03:43] <twb> Come to think of it, I can't remember the last non-rack case I shipped...
[03:43] <arrrghhh> well this server is for my house
[03:43] <twb> qman__: hope you put in three fans, too
[03:43] <arrrghhh> no server rack here unfortunately
[03:43] <qman__> actually 8
[03:44] <arrrghhh> yea seems like you'd want to load up on fans if you have that many disks...
[03:44] <lifeless> that or put them outside
[03:45] <twb> lifeless: disks in the sunshine?  :P
[03:45] <qman__> it does the job, but 'hard to work on' is an understatement
[03:45] <qman__> too many wires
[03:46] <twb> Obviously you need wireless disks!
[03:47] <_GoRDoN__> I actually have 10 disks in their own box next to computer..
[03:47] <_GoRDoN__> Connected with esata... bit slow but works
[03:48] <qman__> some of the connectors on the power supply broke at one point
[03:48] <qman__> so to power the last four drives, I have a SATA to two molex adapter, hooked to two molex to two SATA adapters
[04:01] <kieppie> hi all. I run mostly an Ubuntu/Debian network, & a pfSense firewall. I'm looking for a way of specifying my apt-cache proxy in the DHCP options. any ideas, please?
[04:29] <twb> kieppie: you mean, you want the DHCP client to learn about your apt-cache proxy from the DHCP server, and to tell apt to use it?
[04:30] <kieppie> twb: that is correct
[04:33] <twb> kieppie: can't be done
[04:33] <twb> Rather: there is no existing infrastructure, but you could write your own by hijacking a DHCP option number, and writing custom dhclient post-hooks.
[04:34] <qman__> yeah, but I'm assuming the reason you are even pursuing this is for zero configuration apt clients
[04:34] <qman__> and that defeats that purpose
[04:35] <qman__> better option is a transparent proxy discriminating on apt sources
[04:56] <KREDO> privet vsem u menya fujitsu siemens s3, ne mogu ustanavlivat 11.04 server, pomogite!

[05:58] <Ursinha> good morning
[07:19] <philipballew> I wanna set up key authentication on my ubuntu server. any idea?
[07:20] <jpds> Key auth, for SSH?
[07:23] <philipballew> jpds, yeah, can someone tell me about that
[07:23] <philipballew> safer i assume?
[07:25] <greppy> generally, yes.
[07:25] <jpds> philipballew: Put the public keys for your SSH key into ~/.ssh/authorized_keys, profit.
[07:25] <greppy> http://pkeck.myweb.uga.edu/ssh/
[07:25] <greppy> should have some decent info
[07:25] <jpds> philipballew: https://help.ubuntu.com/community/SSH/OpenSSH/Keys
[07:26] <philipballew> whats the best way to move the key to my server?
[07:26] <greppy> in it's simplest form, you use ssh-keygen to generate a key, then put the .pub file contents into authorized_keys on your remote system.
[07:26] <philipballew> the sever is currently with me, but it wont always be
[07:26] <jpds> philipballew: scp ?
[07:26] <jpds> philipballew: ssh-copy-id ?
[07:26] <greppy> the pub version is "safe" to transfer unencrypted if you have to, but scp/sftp is preferred.
[07:27] <greppy> treat the private key with the same paranoia that you would the security of /etc/shadow
[07:28] <philipballew> would a simple flash drive be easy enough?
[07:28] <philipballew> would a simple flash drive be easy enough?
[07:29] <greppy> just don't loose it or let someone else have it :)
[07:30] <greppy> if they have the private key, they can get in.
[07:32] <philipballew> makes sence. ubuntu server is a manual mount system correct?
[07:33] <greppy> "it depends" :)
[07:33] <philipballew> well i can install usb mount
[07:33] <philipballew> or pmount
[07:33] <philipballew> something like
[07:33] <philipballew> that
[07:37] <lynxman> Ursinha: morning :)
[07:37] <ethana2> Ok, so I'm trying to install Ubuntu Server 11.04 in VirtualBox 4.1.. I start up the vm, set a few options, and then when I select 'install', it just sits there black.
[07:42] <ethana2> I've got PAE enabled in the vm manager
[08:09] <twb> Sigh.
[08:10] <twb> So <managers> made me remove PRUNEFS from updatedb.conf on their favourite shell server, so locate would work there with the stuff in NFS.
[08:10] <twb> Now they're complaining because root_squash is still preventing information disclosure
[08:11] <twb> Dollars to doughnuts they'll want to remove root_squash, too :-/
[08:38] <tommy_nmw> hello everyone
[08:39] <tommy_nmw> I want to copy or backup of my existing ubuntu server with full package installed at work, and bring that image on portable HDD drive and take it home and install it on my home pure Ubuntu server which is without internet
[08:40] <tommy_nmw> How could I do without installing any other extra software ?
[08:40] <twb> tommy_nmw: does the airgapped machine have only main enabled, or also universe?
[08:41] <tommy_nmw> twb: I am sorry I don't understand airgapped machine ?????
[08:41] <twb> tommy_nmw: "airgapped" means it has no internet
[08:42] <_ruben> a home without internet, that must be horrible
[08:42] <twb> _ruben: I am rapidly getting there
[08:43] <tommy_nmw> twb:  It is only a computer with no installation
[08:43] <twb> _ruben: I want internet, my brother works for iinet, so he wants to get an iinet plan, but doesn't want to pay for it.
[08:43] <twb> _ruben: I'm getting to the point where I just say "fuck it, you have whatever you want, and I won't use it"
[08:43] <tommy_nmw> twb: no ubuntu installed yet
[08:43] <twb> tommy_nmw: ah, OK
[08:43] <twb> tommy_nmw: you can do a base install using a server CD; you don't need an internet connection.
[08:44] <twb> tommy_nmw: it just means you won't have any security updates automatically installed from the internet.
[08:44] <tommy_nmw> twb: yes. I will do
[08:44] <tommy_nmw> twb: I am just thinking how to copy HDD image to clone to unpartition HDD of my home computer
[08:45] <twb> tommy_nmw: I advise against that.
[08:45] <tommy_nmw> twb: If it is the only solution, I will try to install basic server install on home computer with server CD first
[08:52] <tommy_nmw> hello anyone can help me?
[08:53] <tommy_nmw> I want to copy or backup of my existing ubuntu server with full package installed at work, and bring that image on portable HDD drive and take it home and install it on my home pure Ubuntu server which is without internet.How could I do without installing any other extra software ?I am just thinking how to copy HDD image to clone to unpartitioned HDD of my home computer.
[08:58] <kim0> tommy_nmw: checkout clonezilla
[09:01] <tommy_nmw> kim0: is there any user friendly guide? can we save image directly from clonezilla to portable USB HDD drive ?
[09:01] <tommy_nmw> kim0: do you mean clonezilla live CD?
[09:02] <kim0> tommy_nmw: yes, and yes
[09:03] <tommy_nmw> kim0: chinese stuffs. no USA stuffs ?
[09:03] <tommy_nmw> kim0: i m just kidding
[09:03] <kim0> :)
[09:03] <tommy_nmw> kim0: may be chinese are better or smarter at cloning like doing pirate Copy as the whole world know
[09:05] <tommy_nmw> kim0: btw, http://clonezilla.org/related-live-cd.php shows 3 links
[09:06] <tommy_nmw> kim0: what do I download ?
[09:06] <kim0> tommy_nmw: neither, this one http://clonezilla.org/downloads.php
[09:08] <tommy_nmw> kim0: thanks
[09:09] <tommy_nmw> kim0:  thanks mr kimchi
[09:09] <kim0> you're welcome
[09:45] <Aaron__> is there a dhcp server included into the cdrom for ubuntu server
[09:47] <Aaron__> Hello?
[09:47] <Jeeves_> Yes, multiple, I thuink
[09:48] <Aaron__> just checking if anyone was awake. lol
[09:48] <twb> I was gonna say "mm, kimchi" but I can't remember the hangul keyboard layout anymore :-(
[09:48] <twb> 김시 ?
[09:48] <twb> Damn, close
[09:51] <Aaron__> i'm trying to install 2 servers a DCHP and a samba server, but when i'm installing the system i'm having problems, but i need to have it all local no internet on this machine
[09:52] <Aaron__> if I could use x11 i could do it I think but I'm trying to do it with out plus it won't let me install a x11
[09:53] <Aaron__> i'm using 11.04
[09:55] <Aaron__> any help?
[09:56] <CloudAche84> try sudo tasksel
[09:57] <Aaron__> it keeps saying when I try to install the packages that it's stalled
[09:58] <CloudAche84> using the above cmd?
[09:58] <tommy_nmw> how could I install phpmyadmin offline  to the correct path ?
[09:59] <tommy_nmw> like we install using apt-get install phpmyadmin
[09:59] <Aaron__> What i'm going to do is reinstalled because I've screwed it up so much so I will talk to you guys in a bit
[09:59] <CloudAche84> when you reinstall just select "select packages manually" during installation and you should be able to selec DHCP3
[09:59] <CloudAche84> I think
[09:59] <CloudAche84> :)
[10:00] <Aaron__> it's not there but I saw a different dhcp sever but it always say stalled
[10:10] <tommy_nmw> kim0:
[10:10] <tommy_nmw> hi
[10:11] <tommy_nmw> the two computers will be different  including model and disk size. does that matter to restore well ?
[10:14] <tommy_nmw> hi all
[10:15] <tommy_nmw> with clonezilla live, can we restore backup of 80GB sized ubuntu server to 40GB sized machine ? I used only partition to image type. not disk to image.
[10:29] <kim0> tommy_nmw: it should work yeah, please read up more info at clonezilla website
[10:30] <tommy_nmw> kim0: my home server is just PC nothing installed yet. even basic ubuntu server version. is that ok ?
[10:30] <kim0> I *guess* .. you need to read more information
[10:37] <tommy_nmw> kim0: ok
[12:26] <Daviey> adam_g: Were you able to send that mail?
[14:23] <skrite> hey all, i am building a server with mysql-cluster and apache searvers across either 3 or 4 computers.. how is load balancing handled for a setup like this?
[14:43] <pythonirc101> when will the python-matplotlib package be updated? Any ideas?
[14:45] <TheEvilPhoenix> pythonirc101:  no clue.
[14:45] <TheEvilPhoenix> we don't know when packages will get updated
[14:46] <Pici> pythonirc101: Why does it need to be updated?
[14:46] <TheEvilPhoenix> you know i am also curious which release they're using...
[14:47] <TheEvilPhoenix> i assume natty
[14:47] <TheEvilPhoenix> but i may be wrong
[15:06] <Dori922> im getting a "Read from Socket failed: Connection reset by peer // Connection closed by 172.19.1.x" when i try to SSH into my UEC node.. my router doesnt have a firewall though so i dont know whats wrong
[15:32] <RNDguy> Hello , could someone please tell me how to enable/configure my second nic during an install of natty. I paused the install , opened a shell , but there is a remarkable absence of ifconfig.
[15:33] <RNDguy> what command can i use instead?
[15:47] <ChmEarl> RNDguy, cat >>/etc/network/interfaces<<EOL
[15:48] <ChmEarl> type in your lines, then EOL
[15:52] <RNDguy> ok i was able to edit it
[15:52] <RNDguy> so how do i restart networking now
[15:53] <RNDguy> thnx for taking the time btw
[16:20] <RNDguy> @ChmEarl Made it work another way . I mapped the server on the other network with another computer , just the time to install it. Thnx anyway.
[16:23] <hallyn> smoser: I just got the thing in oneiric where libvirt needs to be stopped and restarted for it to see cgroups
[16:24] <hallyn> this could be ugly
[16:25] <smoser> hallyn, i actually see cgroups-bin not getting mounted on boot also
[16:25] <lynxman> hey smoser o/
[16:25] <smoser> libvirtd-bin should correctly restart
[16:25] <smoser> and should apparently start after cgroups-bin
[16:26] <smoser> lynxman,
[16:26] <smoser> ho
[16:26] <smoser> hi ho
[16:26] <lynxman> :)
[16:27] <smoser> whats up?
[16:28] <lynxman> smoser: not much, trying vlan support on diablo and playing with upstart, let me know if I can help to test libvirt-lxc
[16:29] <smoser> lynxman, so.. i had it working on the plane..
[16:29] <smoser> and odn't know what was wrong
[16:29] <smoser> :)
[16:29] <lynxman> smoser: hah, the plane magic
[16:29] <smoser> yeah... so i suspect race condition was making it work.
[16:30] <lynxman> hah
[16:39] <zul> smoser: it must be the greenland effect
[17:06] <zul> RoAkSoAx: are you going to do some documentaiton on how to boot cobbler with real hardware with ensemble?
[17:07] <Daviey> RoAkSoAx: kicking off a wiki page would be a BIG help
[17:07] <RoAkSoAx> zul: yes...
[17:07] <RoAkSoAx> Daviey: and that';s what I was planning
[17:07] <RoAkSoAx> zul: Daviey though, there's still things that need to be tested/merged into ensemble's trunk because all the work has been based of a branch I had
[17:07] <RoAkSoAx> which has changed due to refactoring code done by fwereade
[17:08] <zul> RoAkSoAx: k was thinking of updating cobbler this week as well
[17:08] <RoAkSoAx> zul: Daviey so at the moment,s thinsg that I do get changed due to re-factoring on ensemble
[17:09] <Daviey> RoAkSoAx: do you know when it will land?
[17:09] <RoAkSoAx> Daviey: not really
[17:09] <RoAkSoAx> Daviey: that's all in hands of fwereade
[17:10] <RoAkSoAx> err that's all in fwereade's hands
[17:10] <Daviey> RoAkSoAx: do you want to chase to get an idea?
[17:10] <RoAkSoAx> Daviey: i've been chasing for the past couple weeks and yet,things are not fully in trunk
[17:11] <RoAkSoAx> Daviey: I hope things will land by the end of this week though
[17:11] <Daviey> SpamapS: Have you applied for a blanket FFe for ensemble>
[17:11] <Daviey> ?
[17:15] <adam_g> Daviey: WRT to that email, just got to an internet connection. gonna craft it now
[17:15] <Daviey> adam_g: you rock star.
[17:17] <RoAkSoAx> Daviey: zul btw... check the new cobbler ubuntu look kirkland did during the past week
[17:17] <SpamapS> Daviey: no, we're preparing that now. :)
[17:20] <hallyn> kirkland: hey, http://people.canonical.com/~serge/ipxe.debdiff works great for me.  Do you mind pushing it?
[17:25] <Daviey> RoAkSoAx: Err, has that been uploaded?
[17:25] <RoAkSoAx> Daviey: the change to the cobbler look and feel for ubuntu? yes
[17:25] <Daviey> oh
[17:26] <zul> hmm..."nov.ec2.archive.ubuntu.com" probably doesnt work when running on a local instance
[17:27] <zul> adam_g: ping have you tried s3 swift/glance  yet?
[17:35] <adam_g> zul: tried it where?
[17:39] <Ursinha> Daviey, :)
[17:39] <Ursinha> Daviey, all of the packages server team care about have ubuntu-server as subscriber?
[17:40] <Ursinha> just checking so I can mark other task as done
[17:41] <zul> adam_g: on the ensemble formulas
[17:42] <adam_g> zul: yeah, the glance formula will store in local file store until a relatoin has been added to swift-proxy, then it will put them there
[17:44] <arrrghhh> hey, some new users.  i want some more opinions on what i should do with my server
[17:44] <arrrghhh> currently i have no RAID, no LVM, just a few hard drives that are partitioned and mounted.  nothing fancy.
[17:44] <arrrghhh> i'm out of disk space, and i need to add more disks
[17:44] <arrrghhh> i like the concept of LVM, but i don't know much about it
[17:45] <arrrghhh> RAID is obviously good for reliability, but it seems I'm going to have to buy 3 more hard disks and I'll only get one extra terabyte out of the deal... which is quite a pill to swallow.
[17:47] <Ursinha> arrrghhh, I haven't tried to work with several physical hard drives with LVM, I use it only with one hd
[17:47] <Ursinha> so I don't know if it has specific issues on this part, but other than that it works pretty well
[17:47] <Ursinha> I'd at least give it a try (if possible)
[17:47] <arrrghhh> hrm
[17:47] <arrrghhh> i guess i don't see the advantage of LVM on one hard disk?
[17:48] <arrrghhh> just the ability to easily add more space on-the-fly?
[17:48] <Ursinha> pretty much
[17:48] <arrrghhh> do you have raw unpartitioned space on your hard disk?
[17:48] <Ursinha> no
[17:48] <arrrghhh> huh.  i guess i just sliced up my entire hard disks and use 'em until they're almost empty
[17:48] <arrrghhh> then i try to plan a few months out, so i get more space before it completely runs out :D
[17:49] <Ursinha> hahaha
[17:49] <Ursinha> I believe you can avoid that with lvm
[17:49]  * Ursinha reads docs so it won't talk nonsense here
[17:49] <arrrghhh> avoid...?  i'll always need to add moar disks.
[17:49] <arrrghhh> i've read docs on LVM.  just not sure that's the best option for *me*
[17:50] <arrrghhh> although there might be aspects I'm not grasping on LVM, having only read docs and never actually using it...
[18:05] <bluefrog> arrrghhh, what's your server for? business? then RAID + LVM. home? then LVM enough
[18:06] <arrrghhh> yea just home
[18:06] <arrrghhh> it seems like LVM would be enough
[18:06] <RoAkSoAx> zul: the pre-installed image from the pandboard is omap or omap4?
[18:06] <arrrghhh> obviously i'd get no redundancy
[18:06] <arrrghhh> so if a hard disk does fail, that data is gone.
[18:07] <zul> omap4
[18:07] <bluefrog> arrrghhh, raid and/or lvm is not backup.
[18:08] <arrrghhh> bluefrog, i'm not talking about a backup
[18:08] <arrrghhh> i'm talking about reliability
[18:08] <RoAkSoAx> zul: did you experience any problems with minicom?
[18:08] <RoAkSoAx> zul: for some reason it just doesn't display anything
[18:08] <arrrghhh> as i understand it, with a RAID5 array i could survive one complete disk failure
[18:08] <bluefrog> arrrghhh, "that data is gone"  you're talking about backup
[18:08] <zul> RoAkSoAx: in mincom?
[18:09] <arrrghhh> with LVM, there's no reliability, just a better way to manage disks.
[18:09] <RoAkSoAx> zul: yeah
[18:09] <zul> RoAkSoAx: you sure you are using the right serial port?
[18:09] <bluefrog> arrrghhh, home server. am pretty sure ou can survive a few days without your server running...
[18:10] <RoAkSoAx> zul: yes
[18:10] <zul> RoAkSoAx: is it powered on? ;)
[18:10] <RoAkSoAx> zul: i'm thinking it my be my partitions of the sd card
[18:10] <RoAkSoAx> zul: of course lol
[18:11] <zul> RoAkSoAx: probably i had the same problem i had to re fdisk the thing
[18:11] <arrrghhh> bluefrog, i just want to make sure i understand the pros & cons.  i don't really have a backup scheme in place, there would just be too much data to backup.  i would basically need another file server to backup the original file server.
[18:12] <arrrghhh> i have vital data backed up, but there's a lot i would consider not vital.
[18:12] <RoAkSoAx> zul: how many and type of partitions did you create?
[18:12] <zul> RoAkSoAx: iirc i created one big linux partition and let the installer redo it
[18:12] <pmatulis> arrrghhh: how much data are we talking about?
[18:12] <arrrghhh> pmatulis, i'm almost to 3tb
[18:13] <arrrghhh> looking at adding at least another tb, probably 2...
[18:13] <arrrghhh> but it's lunchtime, sorry.  i'll bbl.
[18:13] <bluefrog> pirated movies, songs i definitely not vital
[18:14] <bluefrog> except if you own the original dvd of course
[18:14] <bluefrog> in tha case not vital either as you have the original
[18:14] <bluefrog> so lvm will be fine
[18:15] <pmatulis> a 2TB USB drive goes for around $110 'round here...
[18:15] <RoAkSoAx> zul: the power on buttoin is the closes to the SD car right?
[18:15] <zul> i think so, mine is not in front of me
[18:16] <RoAkSoAx> zul: well that's the one that messes up with the small grenn light :)
[18:16] <zul> :P
[18:17] <RoAkSoAx> zul: unless it requires me to connect it to a monitor?
[18:17] <zul> it doesnt
[18:17] <zul> check on #ubuntu-arm
[18:25]  * RoyK sticks to debian for ARM devices - better support for older CPUs
[18:46] <RoAkSoAx> zul: did you partition your sdcard in any specific way?
[18:58] <zul> RoAkSoAx: dont think so
[19:07] <RoAkSoAx> zul: did you create just 1 partition and formatted it or did you remove any partitions and just copied the ubuntu image
[19:07] <zul> i created one image and did nothing else with it
[19:16] <RoAkSoAx> zul: never mind figured it out :) it's trying to netboot apparently now at least
[19:16] <RoAkSoAx> heheh
[19:21] <zul> RoAkSoAx: cool
[19:22]  * RoAkSoAx off to lunch\
[19:26] <medberry> When installing a lot of machines (virtual or otherwise) with the Ubuntu Server installer, I see DHCP IP exhaustion as each machine ends up with two leases. A temp one (possibly with the generic name "ubuntu") and then the final name of the machine. Anyone know the preferred way to configure ISC DHCPD to only issue a single IP per MAC? I thought using "duplicates" in the dhcpd.conf would do the trick but apparently not.
[19:38] <hallyn> RoAkSoAx: hey, whenever you get a chance, would you mind uploading 2 libcgroup updates for me?
[19:38] <hallyn> RoAkSoAx: http://people.canonical.com/~serge/lucid-libcgroup.debdiff for lucid ,
[19:38] <hallyn> RoAkSoAx: and http://people.canonical.com/~serge/maverick-libcgroup.debdiff (on top of maverick-updates) to maveirck?
[19:39] <hallyn> RoAkSoAx: (biab) thanks!
[19:49] <fowlduck> does upstart respect LSB headers of scripts in /etc/init.d/* that are run via /etc/rcn.d/S*?
[19:49] <fowlduck> I'm wondering about the interaction between the two systems
[19:52] <Psi-Jack> Does Ubuntu's server kernel have a CPU limit on it, to how many it will address? Anyone know what that is, for 10.04 LTS?
[19:56] <RoyK> Psi-Jack: IIRC 32 cores maximum
[19:56] <RoyK> or 64
[19:56] <Psi-Jack> So to get 48, I might have to recompile. hmmm
[19:56] <RoyK> should be sufficient for most setups
[19:57] <RoyK> Psi-Jack: try it - I don't remember if it's 32 or 64
[19:57] <RoyK> recompiling the kernel with 48 cores shouldn't take too long, though :P
[19:57] <Psi-Jack> Heh, I don't actually have the servers yet, specced them out and starting the process up the chain of command. ;)
[19:57] <Psi-Jack> Oh, I know, I just was curious how much work I'd have to do to get it up there. ;)
[19:58] <RoyK> I have a few 2x12 core machines
[19:58] <RoyK> those work welll
[19:58] <RoyK> s/.$//
[19:58] <Psi-Jack> I'm getting 3 4x12 CPU servers. ;)
[19:58] <RoyK> how much memory?
[19:58] <Psi-Jack> 256 GB
[19:58] <RoyK> nice :)
[19:58] <RoyK> for what use?
[19:58] <Psi-Jack> he
[19:58] <Psi-Jack> Database servers.
[19:59] <RoyK> wtf?
[19:59] <RoyK> 3x48 cores for - what - databases?
[19:59] <Psi-Jack> Yep. ;)
[19:59] <RoyK> lots of stored procedures or something?
[19:59] <RoyK> most DB load I see is i/O
[20:00] <Psi-Jack> Nope. We need these servers to handle a LOT of load.
[20:00] <RoyK> database load without stored procedures is typically I/O bound
[20:00] <Psi-Jack> It's a lot of Disk, yes, but when you have 2,000+ database connections and replication going on, CPU load does go up.
[20:00] <RoyK> but 48 cores?
[20:00] <RoyK> seems overkill to me
[20:01] <Psi-Jack> Hey, I specced it out to 2x8, initially. LOL
[20:01] <RoyK> our 24core machines are compute nodes
[20:01] <Psi-Jack> It was the company that suggested going up higher for upwards scaling.
[20:01] <Psi-Jack> Well, the datacenter techs anyway. ;)
[20:01] <Psi-Jack> I said.. Okay...
[20:01] <RoyK> heh - seems they wanted to sell a bit more
[20:02] <RoyK> I'd love to see the performance rating on those, though
[20:02] <Psi-Jack> Heh
[20:02] <RoyK> probably 80-90% idle
[20:02] <Psi-Jack> Yeah, it's also gonna be running pacemaker
[20:02] <Psi-Jack> And MySQL is the database server itself.
[20:02] <RoyK> you'll need to have a LOT of stored procedures to make a database server use 48 cores
[20:02] <RoyK> ouch
[20:02] <RoyK> mysql sucks rather badly
[20:03] <Psi-Jack> I know this.
[20:03] <Psi-Jack> Convincing them to switch to PostgreSQL hasn't worked yet.
[20:03] <RoyK> I guess you would have been doing good with a quad or two
[20:04] <RoyK> or hex, since you're on opteron
[20:04] <Psi-Jack> Yeah. But either way, not my money. I wanted something high performance, they wanted to attach it to the EMC SAN.
[20:04] <RoyK> fewer, faster cores will do better on mysql
[20:04] <Psi-Jack> I didn't like the idea of the SAN for it, but looking at a lot of the specs for it, 4Gb/s FC to FC Disks seems to have some pretty high performance.
[20:04] <RoyK> it can't balance load over several cores for a single query
[20:05] <Psi-Jack> Eh? MySQL's threaded, though, are you /sure/ about that statement?
[20:05] <RoyK> it's threaded, sure, but a single query won't run on several cores
[20:06] <RoyK> even postgres can't do that in most circumstances
[20:06] <RoyK> or at all
[20:11] <Psi-Jack> Welp, Looking at the kernel-ppa configs, it's 64. ;)
[20:13] <RoyK> Psi-Jack: ?
[20:14] <Psi-Jack> http://kernel.ubuntu.com/~kernel-ppa/configs/lucid/amd64--server  -- CONFIG_NR_CPUS
[20:15] <RoyK> 64
[20:15] <Psi-Jack> Yep. :)
[20:15] <RoyK> still, I doubt you'll be able to use them all with myqsl
[20:15] <RoyK> s/myqsl/mysql/
[20:16] <RoyK> with some 100 concurrent queries, you should, but most of the load is i/o bound and every query will normally be executed in a single thread
[20:28] <jodie> anybody doing xen on ubuntu server 10.04.3 LTS?
[20:45] <medberry> When installing a lot of machines (virtual or otherwise) with the Ubuntu Server installer, I see DHCP IP exhaustion as each machine ends up with two leases. A temp one (possibly with the generic name "ubuntu") and then the final name of the machine. Anyone know the preferred way to configure ISC DHCPD to only issue a single IP per MAC? I thought using "duplicates" in the dhcpd.conf would do the trick but apparently not. hallyn, zaid_h zu
[20:45] <medberry> l does this ring any bells?
[20:53] <Rickmasta> Hey guys, I have an unmanaged vps running ubuntu, it does not have cpanel or directadmin.
[20:53] <Rickmasta> How can I set up a domain on my vps?
[20:56] <sheepherd> hey guys what do you recommend? ubuntu server 64x LTS or 11.04?
[20:57] <arrrghhh> 10.04 on a server
[20:57] <arrrghhh> 11.04 on a desktop
[20:58] <arrrghhh> well, i wouldn't recommend 11.04 because of Unity, but that's another story.
[20:58] <arrrghhh> on a server, i usually recommend people stick to LTS releases.
[20:58] <sheepherd> hehe ye i know im really happy i can just choose ubuntu classic ;)
[20:59] <sheepherd> whats the reason?
[20:59] <arrrghhh> for sticking with LTS?
[20:59] <sheepherd> yea. cuz i mean why would they release any other server version than LTS if it wasnt better?
[21:00] <sheepherd> or did stability decrease with the additional features?
[21:01] <RoyK> joschi: last I checked, xen wasn't supported
[21:03] <RoyK> sheepherd: I'd never use 11.04 on a server unless it was a test machine
[21:03] <RoyK> sheepherd: LTS is well kept after for stability, for the non-LTS releases, that seems to be a bit more slack
[21:05] <sheepherd> RoyK: k... well i guess i'll stick with 10.04 then. thx :)
[21:05]  * RoyK still have 8.04 on some servers 
[21:06]  * w00 has 11.04 on all Ubuntu servers
[21:07] <arrrghhh> lol w0
[21:07] <arrrghhh> way to dilute the conversation :P
[21:07] <arrrghhh> 8.04... isn't that expiring soon?
[21:07] <arrrghhh> i guess security patches until 2013
[21:07] <w00> To each his own :)
[21:08] <arrrghhh> w00, for a production server i wouldn't want to do a complete distro upgrade every 6 months.
[21:08] <RoyK> arrrghhh: never fix a winning team
[21:09] <arrrghhh> lol
[21:09] <arrrghhh> RoyK, unless it runs out...
[21:09] <RoyK> arrrghhh: well, iirc there's 18 months support for the non-LTS releases
[21:09] <arrrghhh> just had some poor sap trying to get his 6.06 box up on 8.04 the other day...
[21:09] <RoyK> still low if you have 50 servers
[21:09] <arrrghhh> you're right, server support is a little longer
[21:09] <arrrghhh> but still
[21:09] <arrrghhh> i am lazy :D
[21:10] <RoyK> most good sysadmins are :P
[21:10] <arrrghhh> hehe
[21:10] <RoyK> the eager ones install jalladistro-2012-0.1.alpha and get sacked a week later
[21:11]  * RoyK is off to bed - nite guys (or gels)
[21:11] <arrrghhh> yea, i'd rather have crap work
[21:11] <arrrghhh> cya
[21:11] <sheepherd> you guys all have the LPI certificate? does that prove any skill as sysadmin?
[21:11] <arrrghhh> not i
[21:12] <arrrghhh> i manage all sorts of servers at work, none of them Ubuntu... my Ubuntu Server sits in my house ;)
[21:37] <Daz___> Hi. I have a server I want to install Ubuntu server 11.04 on. The problem is that the raid-option in the bios seems not supported in ubuntu. Is there a fix to be able to use the raidsystem using Intel® C204 PCH Chipset?
[21:55] <SpamapS> Daz___: what kind of RAID do you want to do?
[22:07] <Daz___> raid1
[22:23] <Jeeves_> Does anyone use Ruby around here?
[22:38] <CluelessPerson> Hello everyone.
[22:39] <CluelessPerson> I just built a new dedicated server.
[22:39] <CluelessPerson> and now I need to know what distribution of linux I need to install on it
[22:40] <CluelessPerson> 64 bit -  i3  with hyperthreading, 8GB of ram
[22:41] <CluelessPerson> could someone tell me which linux distribution may serve me best?
[22:41] <Jeeves_> CluelessPerson: Since you're in #ubuntu-server
[22:41] <Jeeves_> the answer will probably be 'Ubuntu'
[22:41] <Jeeves_> :)
[22:42] <CluelessPerson> Jeeves_ I figured. :p  I used Ubuntu headless 32bit on my previous server, modified 2001 P4 1.8ghz 512 ram
[22:42] <CluelessPerson> my new dedicated server, 3.1 ghz (overclockable) i3 with 8GB ram, SSD system drive :D
[22:42] <CluelessPerson> much better and much more fun. :D
[22:42] <CluelessPerson> damn, I don't want to leave for work in 8 minutes. ;_;
[22:44] <CluelessPerson> spent $450 on this server
[22:44] <CluelessPerson> well, desktop to be my server. >:3
[22:45]  * CluelessPerson has a sadface.
[22:46]  * CluelessPerson wishes he could skip work today and setup his new minecraft server. >:)
[22:46] <Jeeves_> Why?
[22:46] <Jeeves_> Someone's gotta pay for your new server :)
[22:46] <CluelessPerson> Already paid for. >:)
[22:46] <CluelessPerson> Next I'll probabaly be saving up for a $1200 camera
[22:47] <CluelessPerson> then $1000 for an i7 16GB 3.1GHZ desktop.
[22:47] <CluelessPerson> garRRRR
[22:49] <CluelessPerson> Jeeves_  How might I achieve sending different sub-domains down different ports?
[22:49] <Jeeves_> you don't
[22:50] <CluelessPerson> Jeeves_  just thinking of how I might handle different minecraft worlds on the same server.
[22:50] <CluelessPerson> it's so creative. :D
[22:50] <Jeeves_> I've got no clue what minecraft is
[22:51] <CluelessPerson> Jeeves_  really?  It's a very pixelated building world.
[22:51] <CluelessPerson> Jeeves_ Think legos but much much much more versatile.
[22:52] <CluelessPerson> Jeeves_   you can basically set/change blocks across a huge generated landscape and build, explore, and more
[22:52] <CluelessPerson> Jeeves_ make sure to look it up, but I have to go NOW
[22:52] <CluelessPerson> Jeeves_  I have work in 8 minutes, thanks for the talk, leaving!!!
