J_Panyone are using with sucess KVM on 7.4 ?03:01
fooHm, what is a better scenario for better IO throughput: a server with 6 500GB drives on RAID5, or 6 separate 500GB drives? 03:06
fooWe're going to try the former with the dell 295003:06
Kamping_Kaiserfoo, i'd go with raid03:08
fooThat's what I thought. Someone is telling me he thinks 6 drives without RAID and storing files across all the drives and what not will result in better throughput, but I'm not too sure03:09
fooBut, I'm not too sure03:09
fooAny input is appreciated, thanks03:10
Kamping_Kaiseri'm asuming scsi, but i dont think 6 drives would be better03:10
foooh, SATA, I think03:11
fooYeah, pretty sure it's SATA03:11
fooYeah, I don't think so either03:11
fooThanks 03:11
Impaquefoo: the RAID5 is not the speed king03:16
Impaquefoo: RAID1 is ;)03:17
fooHm, you're kidding - right?03:18
fooheh03:18
Impaquesorry, 003:20
Kamping_Kaiser0=striped?03:21
Impaqueyep03:21
Impaque1 is mirrored03:21
fooRight03:21
foo0 does not have redundancy03:21
Impaquebut still, raid5 should be faster than n independent drives03:21
Kamping_Kaiser0 is fast to write, but reading theres no speed gain is ther?03:22
fooWe do more reads than writes as well03:22
ImpaqueKamping_Kaiser: hm, the reads should also be alleviated via striping, so reads should be faster as well03:22
Kamping_KaiserImpaque, but on mirroring it can read both discs, for any data, with striping it has to read set bits of each disc03:26
=== Kamping_Kaiser shuts up - cant remember, shouldnt argue it
=== jhutchins [n=jonathan@64-151-34-11.dyn.everestkc.net] has joined #ubuntu-server
Impaquethe data is read in parallel from several discs, less seeking occurs03:28
fooImpaque: Are you still implying RAID0 is faster than RAID5 ?03:30
fooOnly difference between RAID0 and RAID5 is that RAID5 has data redundancy, IIRC03:31
Impaquebut that also means you use n-1 drives (the capacity of one drive, spread across all of them, is used for parity only. thus, data "spreading" is less than RAID0 with same amount of drives, where even less seeking occurs while reading)03:32
ImpaqueRAID0 is used in video/audio production a lot03:34

yashtonquestion: I'm running Ubuntu server 7.04, on original install, i selected dvorak keyboard layout, thinking i'd want to try it, but now i want a regular qwerty setup. I've tried to install console-data and run dpkg-config on that. Also tried to use loadkeys, but i can't find where ubuntu stores keyboard layouts.05:51

nictukuI don't use 7.04 so I don't know. usually dpkg-reconfigure -plow console-data should work06:10

shawarmacoNP: If you fetch the squirrelmail source, there's an UPGRADE file that might be helpful.01:41
shawarmacoNP: I don't use squirrelmail, though, so I don't know if it actually *is* helpful, but it seems like a sensible place to start.01:41
shawarmacoNP: It's interesting though that noone reported this. Neither to us, nor to Debian. Do you have a very specialised setup?01:44

Impaquecompared to LTS version, what are the pitfalls of upgrading the non-LTS server versions (like Feisty) ?06:15
Impaquesome general experience hints would be appreciated, because i don't know whether to stick with LTS and it's prolonged EOL, or to grab the bleeding edge06:15
ivoksupgrading to...?06:16
Impaquenew version which appears after 18mo06:16
ivoks6, not 1806:16
ivoksnew version is every 6 months06:16
ivoksand you can upgrade step by step06:17
ivoksso... you can upgrade 6.06 to 6.10, and then 6.10 to 7.0406:17
ivoksyou can't upgrade 6.06 to 7.0406:17
ivoksit really depends on what your server will do06:17
ivoksi have only one server on Edgy (will promote it to Feisty soon), and all others are on LTS06:18
flowolfis anyone using software raid in ubuntu server?06:18

fooHmm, looks like the tech had issues installing ubuntu 6.06 on the dell 2950, and 6.10 ... so he installed 7.04 and he said it worked like a charm. Is this ok for production use?08:53
