[06:09] morning all [06:11] o/ oh hi [06:34] hi guys [06:34] anyone else hit with no power? [06:39] hey Kilos [06:41] hi Theblazehen [06:41] hit ThatGraemeGuy inetpro and others too [06:41] s/hit/hi [07:20] hi JabberwockyA19 [07:26] good mornings [07:26] oh and hi Kilos [07:27] howdy inetpro [07:27] ow why you hit me?! [07:27] when [07:27] im not even there [07:27] hit ThatGraemeGuy inetpro and others too [07:27] :-p [07:28] lol hi man note s/hiy/hi [07:28] wbb sheep time [07:36] good morning [07:36] Maaz: coffee on [07:36] * Maaz flips the salt-timer [07:40] Coffee's ready for charl! [07:42] hi charl [07:42] Maaz: thanks [07:42] charl: Okay :-) [07:42] hi Kilos [07:43] ok i'm asking an operator on freenode to nickserv drop this nickname now [07:43] 09:37 -NickServ(NickServ@services.)- Registered : Aug 29 12:38:26 2012 (1 year, 43 weeks, 5 days, 18:58:59 ago) [07:43] why? [07:43] then i can register it [07:43] ah [07:44] you mean someone else had it [07:44] some *sshole that registered it and never even used it [07:44] 09:37 -NickServ(NickServ@services.)- Last seen : Aug 29 13:02:30 2012 (1 year, 43 weeks, 5 days, 18:34:55 ago) [07:44] ya do that [07:45] like when i started within a week my name was stolen and registered [07:45] morning everyone o/ [07:45] hi JabberwockyA19 [07:45] thats when i swopped to kilos and registered [07:47] hi Vince-0 [07:47] hi Vince-0 [07:48] haai mense [08:10] bbl === SubOracle[away] is now known as SubOracle [08:25] i has it :) [08:28] good no more dragging tail [08:29] lol [08:29] i get no more tail now ? [08:29] oh well i had enough tail already [08:31] haha only if you disconnect and reconnect quickly [08:37] nah i take it slow [12:15] Hi everyone [12:16] 'lo mazal [12:16] Is it possible , with Ubuntu to create a LVM of two drives after install , and the two drives is not part of the OS [12:16] hi mazal [12:18] um [12:18] i think so, but you need to describe in more detail [12:19] paste output of 'sudo fdisk -l /dev/sd?' to http://slexy.org/ [12:19] and also 'mount [12:19] and also 'mount', 'pvs' & 'lvs' [12:19] Here is my scenario , currently my Ubuntu runs on an external HDD. 14.04 [12:19] ok [12:19] Backups runs to another external [12:20] ok [12:20] However , my data ( that get's backed up ) has become too much for the 2TB backup drive. [12:20] right [12:20] Now I am thinking of putting in 2x2TB internals and make one volume of them [12:20] ok [12:21] But without re-installing my OS or installing my OS on the internals [12:21] This possible ? [12:21] so they will just be storage, not hosting any O/S filesystems? [12:21] Correct. OS must stay on external as I use it at home and at work. OS must stay mobile [12:21] cool [12:21] yeah you can do that [12:22] I know zero of LVM so don't even know where to start [12:22] but you realise in that scenario, if 1 disk fails, your entire LVM is irrecoverable [12:22] I just know LVM can make 1 big volume of multiple drives [12:22] i assume you're ok with that since its for backup space [12:22] Yeah that part bothers me a bit , maybe I must just keep two drives seperate and seperate the backups between them [12:23] 2 Seperate shares and just manage what goes where [12:23] or get a third disk and make a RAID5 volume [12:24] I know even less of RAID lol [12:24] but yeah, without RAID, LVM just adds space together, and if a part of it dies the whole volume dies [12:24] Don't one need expensive raid cards for that ? [12:24] nope, linux software raid is perfectly feasible on modern hardware [12:25] Does RAID 5 add space together ? [12:25] RAID5 requires at least 3 disks [12:25] but you only get the usable space of 2 [12:26] what happens is that every piece of data written is written in such a way that 1 missing piece can be re-constructed from the 2 non-missing pieces [12:26] (assuming a 3-disk array) [12:26] so in a RAID5 array with 3 disks, 1 entire disk can be lost and the data can still be read [12:27] So 3x TB disks gives 4tb usable space ? [12:27] 3x 2TB [12:27] correct [12:27] Hmm [12:27] for RAID5, your usable capacity is (n-1) x size of disk [12:27] where n is the number of disks [12:28] for RAID6 you can lose 2 whole disks so your usable capacity is (n-2) x size of disk [12:28] I will think a bit what the best option will be [12:28] All the data will be backups , not live data [12:28] so a RAID6 with 5x 2TB disks gives you 3x 2TB of capacity, and up to 2 disks can fail completely and your data is still accessible [12:29] if it were me and its for backup only I'd just go with RAID0 or LVM [12:29] actually if it were me i'd make it way more complicated probably ;-) [12:30] What's RAID0 ? [12:30] i'd probably split each disk and have a RAID1 for crazy important data and a RAID0 for other stuff [12:30] RAID0 is a "stripe", where your data is split and each disk gets a piece [12:31] so if you lose a disk you lose all the pieces on that disk and the data as a whole is also toast [12:31] similar to LVM, except LVM is more flexible as you can add any old size to an LVM but RAID0 pieces must be of equal size [12:31] So RAID0 will give 4TB as 1 volume , but everything gone if 1 drive fails ? [12:31] yup [12:32] In a 2x 2TB setup [12:32] So RAID0 is same as LVM basically ? [12:34] almost, the members of a RAID0 must be the same size, but you can add any old bit of disk to LVM [12:34] but in terms of "lost 1 piece, lose the whole pie", yes the same [12:34] Ok thanx Greame , will go think about all the options and decide what would be best [12:35] good luck :-) [12:55] Bye everyone === SubOracle is now known as SubOracle[away] [15:31] sorry, swopping modems [17:37] grrrr i forgot the e220 times out [17:37] ohi my superfly [17:38] hows you and the family [17:56] oi oi oi [18:21] Maaz: Tell Kilos Hi, we're all fine. How are you? [18:21] superfly: Got it, I'll tell Kilos on freenode [18:27] ah superfly sorry . i got something wrong here with modems disconnecting all the time [18:27] apart from cold im good too ty [18:27] no problem [18:27] I'm not here all the time [18:28] ya i n oticed [18:28] took my new dlink to xp for a while and since them it seems to timeout like the e220 does [18:28] grrrr [18:37] wb Kilos [18:37] hi superfly [18:37] ty charl [18:38] running mtr to see if timeouts will stop [19:49] night all. sleep tight === SubOracle[away] is now known as SubOracle === SubOracle is now known as SubOracle[away]
