[01:22] <akerok> Hello everyone.  I have a bit of an issure with my ubuntu server.
[01:22] <RoyK> !ask
[01:24] <akerok> I'm running ubuntu server 12.04, and I was trying to configure the IP address to my new static IP so it can be accesses online (it's a web server).  I have to run it in a VM (I'm using Virtual Box for this).  I can no longer access the server using ssh, and I can't get it to allow me to access it directly.  It doesn't even give me the option to log in directly.
[02:23] <pdtpatrick> Why does pvcreate give an error when ran in a script that device is ignored or filtered but running the same command manually works just fine? http://pastie.org/private/unch4uvjjkmmtpimsxwv8q

[05:21] <djx> hello, what's the default image viewer for ubuntu server?
[08:07] <antix> image viewer? there's no gui for ubuntu server...
[11:54] <madc|SPYnX> How to start with the GUI in ubuntu server?
[11:55] <jonbaer> is this the right forum to ask cloud-init questions?
[12:25] <slyboots> Hello
[12:26] <slyboots> Anyone aware of a variant of ubuntu that I can install and "blind-bood"
[12:26] <slyboots> *boot, preferably something that'll auto-start, grab DHCP and start up something like ssh/vnc?
[13:02] <sw0rdfish> jeez
[13:02] <sw0rdfish> what were the websites for european VPS' for 5 or 6 euros again?
[13:13]  * slyboots faceplants
[13:14] <slyboots> Anyone know how you delete a freaking mdadm RAID array?  It keeps rebuilding despite me deleting it..
[13:14] <slyboots> And running mdadm --zero-superblock /dev/sdX doesnt work "mdadm: Unreconginised md component device - /dev/sdX"
[13:20] <RoyK> slyboots: mdadm --stop ?
[13:20] <RoyK> slyboots: then just dd a bunch of zeros on the devices
[13:21] <slyboots> Aye, Thats what Im doing now.. its crazy thats what its come to
[13:22] <RoyK> a few megabytes will do
[13:22] <RoyK> on each device
[13:22] <slyboots> Aye, rebooted and its no-longer seeing the RAID array anymore, weird thats what the solution is though
[13:22] <slyboots> Still trying to figure out the best way to build a NAS, 4x disks.. quite keen to try ZFS but.. eh
[13:23]  * RoyK finds that a rather terrific solution ;)
[13:23] <RoyK> ZFS is cool, but not as flexible as md
[13:23] <RoyK> and under fuse, write speeds suck rather hard
[13:23] <slyboots> I thought it was native, not fuse
[13:24] <slyboots> (Although write-speeds are awful)
[13:24] <RoyK> no native zfs in linux yet, that is, zfsonlinux exists, but probably not stable yet
[13:24] <RoyK> and will probably *never* enter any distro because of licensing
[13:24] <slyboots> Aye, mdadm seems a bit.. I dunno, build it once and it had to resync twice.. :P
[13:25] <RoyK> MD is like, build a mirror, convert to raid-5, add a few drives and convert to raid-6, get low on space, convert to raid-5 again...
[13:26] <RoyK> zfs is like, build a raidz1 VDEV and it'll stay in that form until you remove it
[13:26] <slyboots> Well, thats not a huge problem. I've got a lil hp microserver so it only takes 4x disks anyway
[13:26] <RoyK> but then, zfs has checksumming and support for l2arc and slog, ssd caching
[13:26] <slyboots> But yea, the performance is *awful*
[13:27] <RoyK> slyboots: then use omnios or openindiana or some other illumos distro - there it's native, and pretty neat
[13:27] <slyboots> Yea I tired openindina, spend about a hour sobbing in a corner lol..
[13:27] <RoyK> performance with MD is quite good ;)
[13:27] <slyboots> Yea with mdadm Im getting about 60=80MB/sec over GigE which is about.. wella s much as you can hope for
[13:27]  * RoyK had 350TiB or so on openindiana at his last job
[13:27] <slyboots> ZFS was about.. 20MB/sec?
[13:28] <RoyK> that's because of fuse
[13:28] <slyboots> WEll, might try a native zfs, see if it really makes a difference
[13:28] <RoyK> native zfs is quite fast
[13:28] <RoyK> it won't be as fast as MD, though, because of the checksumming
[13:29] <slyboots> well I figure it shouldnt be slower by a factor of 4..
[13:29] <RoyK> of course, you can turn that off for a dataset, but that somewhat takes away the fun of zfs
[13:29] <RoyK> slyboots: you can't compare native zfs with zfs under fuse...
[13:29] <slyboots> Yea, Checksumming is good.. dedup not so much
[13:29] <RoyK> don't use it
[13:29] <RoyK> I mean DO NOT USE DEDUP ON ZFS
[13:29] <RoyK> I've spent hours testing that
[13:30] <slyboots> Oh neat, OmniOS has a esxi application, ssweet
[13:30] <RoyK> there's a very good reason why dedup never entered Solaris 11
[13:31] <slyboots> Its just awful? :P
[13:31] <RoyK> well, it doesn't work too well, unless you have a terabyte of RAM or so
[13:34] <RoyK> slyboots: but with something illumos, you get snapshotting and perhaps SSD caching (if you have room for that in that microserver)
[13:35] <slyboots> Nah, its pretty tight fit unless I did something over USB/eSATA
[13:35] <RoyK> slyboots: but then, you get snapshotting if you're brave enough to use btrfs, and ssd caching if you're brave enough to use bcache ;)
[13:36] <slyboots> lol, lot of intresting things you can do but.. eh, its only a lil server so.. playing it safe
[13:37] <RoyK> ext4 on MD is safe
[13:37] <RoyK> omnios or openindiana should be safe too
[13:37] <slyboots> Aye, shall be intresting to test em
[13:38] <RoyK> if you have windows clients, snapshots show up under "previous versions" in windows if you have an illumos server (given you use the CIFS server, and not Samba)
[13:38] <slyboots> Ah cool, shadow-copy support?
[13:38] <RoyK> yep
[13:38] <slyboots> Neat :)
[13:44] <RoyK> setup a server on that for a remote office in my last job - never heard a word of anything related to data restores later ;)
[13:44] <RoyK> the autosnapshot service in Illumos is rather good for such things
[13:45] <RoyK> unless you do something stupid as starting to use some file area with snapshotting as a spooling space or temp space
[13:45] <slyboots> heh, we still have to take care of that manually at work :P
[13:47] <RoyK> slyboots: as I said, zfs doesn't support extending VDEVs or changing RAID levels. It supports replacing drives with bigger ones, though (given zpool set autoexpand=on)
[13:47] <slyboots> Kinda shitty like that, odd you cant expland
[13:47] <slyboots> *expand
[13:48] <RoyK> it'll require the famous block pointer rewrite mechanism that was reported to be worked on some three years ago
[13:48] <slyboots> :P
[14:13] <sw0rdfish> errr
[14:19] <RoyK> er?
[14:37] <sw0rdfish> i forgot the website with 6 euro VPS
[14:37] <sw0rdfish> germany based vps
[14:44] <RoyK> no idea
[14:45] <RoyK> google sent me to http://www.alvotech.de/
[14:45] <RoyK> google:vps 6 euro site:.de
[15:15] <slyboots> RoyK: Dont suppose you know any good gides for this OmniOS :P
[15:18] <RoyK> slyboots: just follow the guides for openindiana or even opensolaris
[15:18] <RoyK> same thing, different wrapping
[15:19] <RoyK> slyboots: but if you want to install on a microserver, I guess that only has four drives, are all four of them meant to be used for data?
[15:19] <RoyK> if so, use a pen drive for the root
[15:19] <RoyK> or two
[15:19] <slyboots> AYe, already got that all setup
[15:20] <RoyK> zpool create mydatapool dev1 dev2 dev3 dev4
[15:20] <RoyK> probably something like c0t0d0
[15:20] <RoyK> don't partition them
[15:20] <RoyK> slyboots: btw, /j #omnios for this
[15:21]  * slyboots nods
[17:22] <slyboots> -So..... Filesystems!
[17:22] <slyboots> Its on a home NAS, mostly large files like media.. perforamnce is imporataint so Im thinking either ext4 which appears to be the Go-to FS.. but I've heard xfs is quite good too
[17:28] <RoyK> slyboots: no big difference
[17:29] <RoyK> ext4 is a good allrounder, xfs is perhaps better on large files, but sucks sick through a straw when it comes to metadata operations, like lots of files in a directory
[17:30] <slyboots> Mmm..
[17:30] <slyboots> AYe, I've decided to sod ZFS, at least for now
[17:30] <slyboots> Wills tick with ZFS..
[17:31] <slyboots> Found some awsome tweaks for mdadm thats got the rebuild down from 10+ hours to about 3
[17:31] <RoyK> zfs is good for dedicated storage systems IMHO
[17:31] <slyboots> Aye, I've used FreeNAS and its worked well in the past, no idea why its so god awful inside a VM
[17:32] <RoyK> erm
[17:32] <RoyK> don't use a VM for hosting storage
[17:32] <RoyK> just don't
[17:32] <RoyK> it's stupid
[17:32] <slyboots> Eh, I dont have the hardware to avoid it
[17:34] <slyboots> Maybe in a few months when Im not crazy poor will buy something dedicated
[17:34] <RoyK> then setup the system with native drives and use it for virtualization
[17:34] <RoyK> not the other way around
[17:35] <qman__> actually, that's not true anymore of xfs
[17:35] <qman__> but I don't trust it because it's lost my data more than once
[17:35] <qman__> I'm going to zfs myself
[17:35] <RoyK> qman__: really? they fixed it?
[17:35] <qman__> yes, as of ~3.0
[17:35] <qman__> kernel 3.0 that is
[17:35] <RoyK> ok
[17:35] <slyboots> I dunno, its hard enough getting zfs going inside OpenIndiana, I would dread setting up virtulisation isnide that too
[17:36] <slyboots> Plus, I've no screen for my microserver lol
[17:36] <RoyK> slyboots: it's no problem getting zfs going good in openindiana ;)
[17:37] <RoyK> qman__: I chose !zfs because of the flexibility of MD
[17:37] <slyboots> RoyK: yea but its using it for aother things too, its too.. "Strange"
[17:37] <slyboots> :P
[17:38] <RoyK> slyboots: well, I can't blame you for not knowing what you do, but I can try ;)
[17:38] <jchamb2010> Hi, does anyone here have knowledge of dual NIC setups and wouldn't mind helping me troubleshoot an issue I'm having? More info: http://ubuntuforums.org/showthread.php?t=2100344
[17:38] <slyboots> But yea, mdadm works "Fine" inside a VM enviroment
[17:38] <slyboots> Get about 60-80MB writes, thats about as best as I Could hope
[17:38] <RoyK> slyboots: Just don't run storage servers virtualized
[17:38] <RoyK> slyboots: really
[17:39] <qman__> jchamb2010, you have two gateways, don't do that
[17:39] <RoyK> slyboots: as in *really*
[17:39] <jchamb2010> qman__ : is that really all it is?
[17:39] <qman__> if you need both gateways you need to either set up metrics, or configure load balancing
[17:39] <qman__> otherwise get rid of one
[17:39] <jchamb2010> qman__ : IDK why I didn't try that
[17:41] <qman__> yep, that's all it is
[17:41] <qman__> as-is, they're treated as identical
[17:41] <jchamb2010> I'll try that and see what happens
[17:41] <qman__> and the kernel stupidly assumes that they are identical in every way, and just chooses at random where to send traffic out
[17:41] <qman__> regardless of its nature
[17:41] <qman__> and expects it to come back from either
[17:42] <jchamb2010> I can disable the eth0 though, and eth1 still won't work
[17:43] <qman__> it might not be configured right, or plugged into the right spot
[17:43] <qman__> is 74.91.21.41 pingable through eth0?
[17:43] <jchamb2010> yes
[17:43] <jchamb2010> what you said works though :) i removed a gateway and it started working
[17:45] <qman__> 74.91.31.45 is pingable from here, so it looks like you're all set
[17:45] <jchamb2010> Thank you very much :)
[17:54] <jchamb2010> I replied to the thread with the fix and thanking you. Have a good afternoon :D

[18:59] <SnowBro-> need some help please
[19:02] <SnowBro-> first of all i want to say sorry for my english, it's not my native...now the issue, im NEW to Linux and i pick Ubuntu Server as my option because the great support community that it has, im trying to put to work a machine as a server, i already installes LAMP environment (from tasksel), and i have everything working inside my network (i can access to the server in every machine inside my house), but i dont know how to go out with
[19:02] <SnowBro->  the server, thats my issue, any clues?
[19:15] <rckrd> hey guys, so i've have a small personal server and i want to use it for a few different things (development, music server, etc).  Whats the best way to keep these functions separate?  Virtual machines?  Or just different users and groups?
[19:21] <greppy> rckrd: unless you have LOTS of resources ( RAM & CPU ) just use different users/groups.
