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

[07:20] Key auth, for SSH? [07:23] jpds, yeah, can someone tell me about that [07:23] safer i assume? [07:25] generally, yes. [07:25] philipballew: Put the public keys for your SSH key into ~/.ssh/authorized_keys, profit.

[07:26] 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] the sever is currently with me, but it wont always be [07:26] philipballew: scp ? [07:26] philipballew: ssh-copy-id ? [07:26] the pub version is "safe" to transfer unencrypted if you have to, but scp/sftp is preferred.

[16:23] smoser: I just got the thing in oneiric where libvirt needs to be stopped and restarted for it to see cgroups [16:24] this could be ugly [16:25] hallyn, i actually see cgroups-bin not getting mounted on boot also [16:25] hey smoser o/ [16:25] libvirtd-bin should correctly restart [16:25] and should apparently start after cgroups-bin [16:26] lynxman, [16:26] ho [16:26] hi ho [16:26] :) [16:27] whats up? [16:28] 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] lynxman, so.. i had it working on the plane.. [16:29] and odn't know what was wrong [16:29] :) [16:29] smoser: hah, the plane magic [16:29] yeah... so i suspect race condition was making it work. [16:30] hah [16:39] smoser: it must be the greenland effect [17:06] RoAkSoAx: are you going to do some documentaiton on how to boot cobbler with real hardware with ensemble? [17:07] RoAkSoAx: kicking off a wiki page would be a BIG help [17:07] zul: yes... [17:07] Daviey: and that';s what I was planning [17:07] 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] which has changed due to refactoring code done by fwereade [17:08] RoAkSoAx: k was thinking of updating cobbler this week as well [17:08] zul: Daviey so at the moment,s thinsg that I do get changed due to re-factoring on ensemble [17:09] RoAkSoAx: do you know when it will land? [17:09] Daviey: not really [17:09] Daviey: that's all in hands of fwereade [17:10] err that's all in fwereade's hands [17:10] RoAkSoAx: do you want to chase to get an idea? [17:10] Daviey: i've been chasing for the past couple weeks and yet,things are not fully in trunk [17:11] Daviey: I hope things will land by the end of this week though [17:11] SpamapS: Have you applied for a blanket FFe for ensemble> [17:11]
