[07:04] <xerophyte> anybody useing postfix and saslauthd
[07:05] <xerophyte> i am getting some auth fail werror with ubuntu but fedora core just work fine .. and i tested with testsaslauthd it worked fine
[07:43] <Vaske_Car> anybody have a minute to explane me something?
[07:44] <Vaske_Car> actually I need tutorial to install required aplication to host forum
[01:03] <nawty> guys, gots a question, anyone around?
[01:03] <nawty> HostRAID, is that controller supported in the -server kernel ?
[01:04] <nawty> Intel/Adaptec afaik, SATA.
[01:04] <nawty> Standard in some of our Intel Boxen.
[01:12] <soumyadip> I suppose so
[01:12] <soumyadip> it is there in the stock kernel
[01:13] <nawty> soumyadip: it detects the two sata disks seperately, and not as the raid, where as the vanilla kernel on the gentoo install works perfectly, as does freeBSD
[01:15] <nawty> on FreeBSD it becomes ar0
[01:16] <soumyadip> http://www.ubuntuforums.org/showthread.php?t=34519  <- maybe this would help
[01:16] <nawty> checking quick, :)
[04:13] <nawty> it's the SATA Hostraid, not the SCSI one.
[09:00] <highvoltage> hi there.
[09:00] <highvoltage> i need some help for someone in #edubuntu
[09:00] <highvoltage> this person has 8GB RAM on an LTSP server
[09:00] <highvoltage> so I suggested they install the server kernel.
[09:00] <highvoltage> the problem is, it brings the server to a crawl.
[09:01] <highvoltage> hi Petaris, i'm just about half way explaining your problem :)
[09:01] <Petaris> highvoltage: I didn't even know about this channel
[09:01] <Petaris> hehe
[09:01] <highvoltage> and with a 686 kernel, you'd only be able to use 4GB of the ram on that server.
[09:01] <highvoltage> so what would be the ideal Ubuntu kernel for a big LTSP server?
[09:04] <Petaris> my system is a dual opteron with 8 GB of RAM (4 per cpu) and hardware raid 1 using an LSI MegaRAID SATA PCI-X adapter
[09:14] <ivoks> highvoltage: what's the problem?
[09:14] <highvoltage> ivoks: Petaris is building a big ltsp server, with 8GB RAM
[09:14] <ivoks> ok
[09:14] <highvoltage> the 686 kernel can only see up to 4GB RAM, so he's using the ubuntu server kernel
[09:15] <ivoks> ok
[09:15] <highvoltage> but it brings the machine to a crawl very quickly
[09:15] <highvoltage> so which kernel should he use?
[09:15] <Petaris> my system is a dual opteron with 8 GB of RAM (4 per cpu) and hardware raid 1 using an LSI MegaRAID SATA PCI-X adapter
[09:15] <highvoltage> it's a dual-opteron server, btw.
[09:16] <ivoks> crawl as slow or it dies?
[09:16] <Petaris> slow
[09:16] <Petaris> very slow
[09:16] <ivoks> did you try to figure out why it's so slow?
[09:17] <Petaris> I looked a bit, but didn't find any real obvious reasons
[09:17] <highvoltage> ivoks: well, it's only slow with the server kernel, with the 386 kernel, it was apparently much faster
[09:17] <highvoltage> right Petaris?
[09:17] <Petaris> highvoltage: yes
[09:18] <ivoks> hm...
[09:19] <ivoks> run it with -server kernel
[09:19] <ivoks> and i'll be here next few hours
[09:19] <ivoks> so i can help you debug the problem
[09:20] <ivoks> what version is that?
[09:20] <mdz> highvoltage: what's up?
[09:20] <Petaris> 2.6.15-21
[09:20] <highvoltage> mdz: thanks for coming :)
[09:21] <ivoks> ok, not the latest, but...
[09:21] <highvoltage> Petaris is building a big ltsp server, with 8GB RAM
[09:21] <ivoks> Petaris: install -22 for start
[09:21] <highvoltage> the 686 kernel can only see up to 4GB RAM, so he's using the ubuntu server kernel
[09:21] <highvoltage> but it brings the machine to a crawl very quickly
[09:21] <highvoltage> so which kernel should he use?
[09:21] <mdz> he should use the server kernel
[09:21] <ivoks> to take the most of the ram - server
[09:21] <mdz> if he's having a problem with that kernel, he should report a bug and work with BenC to get it resolved
[09:22] <mdz> otherwise it's just going to bite someone else
[09:22] <highvoltage> he reports that the system runs very, very slow with the server kernel though, and that's with just one thin client connected.
[09:22] <highvoltage> mdz: ok, thanks for that feedback
[09:22] <mdz> highvoltage: that's not a feature
[09:22] <Petaris> ivoks: that is the version that kernel-image-server installed
[09:22] <ivoks> Petaris: i know, but new version is out
[09:23] <highvoltage> Petaris: i think our best bet is to track down BenC, and find out what information he needs to fix it
[09:23] <Petaris> ivoks: ok
[09:23] <ivoks> Petaris: metapackage still doesn't install it, but it will soon
[09:23] <Petaris> highvoltage: right
[09:24] <highvoltage> Petaris: i see he's on #ubuntu-kernel, let's go bug him there :)
[09:24] <ivoks> file a bug
[09:24] <ivoks> but we can work on a problem
[09:24] <Petaris> highvoltage: ok
[09:24] <highvoltage> ivoks, mdz: thanks again for pointing us in the right direction
[09:26] <ivoks> highvoltage, Petaris rarely there is a chance to work on a broken system in real time, so it would be nice if you could give some more informations here on IRC
[09:27] <ivoks> and paste everything to the launchpad bug
[09:27] <Petaris> ivoks: What info would you like?
[09:27] <ivoks> do you run it now?
[09:27] <mdz> highvoltage: np
[09:27] <Petaris> ivoks: any chance this could just be my system?
[09:28] <ivoks> Petaris: all options are open, but we have to start with "it's kernel problem" :)
[09:28] <Petaris> ivoks: yep, its running now
[09:28] <Petaris> just grabbing the -22 kernel
[09:28] <ivoks> keep an eye on load and tail syslog in other window
[09:29] <ivoks> and kernlog in other
[09:29] <highvoltage> Petaris: syslog might be handy, the output of dmesg too (perhaps there's some error somewhere)
[09:29] <highvoltage> Petaris: perhaps also the contents of /proc/cpuinfo. i suppose more informaiton is better than less.
[09:30] <Petaris> right
[09:30] <ivoks> but don't paste it here :)
[09:30] <Petaris> let me install this new kernel first
[09:30] <ivoks> ok
[09:30] <Petaris> maybe this will fix it
[09:30] <Petaris> you never know
[09:31] <ivoks> it has quite large changelog
[09:31] <ivoks> not sure how much of it is related to your problem
[09:35] <highvoltage> the k7 kernels has nothing to do with the opterons, right?
[09:36] <ivoks> no
[09:38] <Petaris> ok its in, rebooting
[09:39] <ivoks> ok
[09:40] <Petaris> server booted, booting client
[09:41] <ivoks> ah.. does server without clients works ok?
[09:41] <Petaris> don't know
[09:41] <ivoks> ok
[09:42] <Petaris> clients up
[09:42] <ivoks> now tail syslog and kernlog
[09:42] <ivoks> and open top to watch over load and apps that grab too much proc
[09:43] <Petaris> its slow again
[09:43] <ivoks> ok, can you work on it at all?
[09:44] <ivoks> just run 'uptime' to see load
[09:44] <Petaris> root@Ayumi:~#  min,  1 user,  load average: 0.40, 0.87, 0.44
[09:45] <ivoks> so, it's not load
[09:45] <Petaris> nope
[09:45] <Petaris> and top isn't showing much either
[09:45] <ivoks> oh... hm...
[09:45] <ivoks> dmesg
[09:45] <ivoks> and try to catch any error
[09:47] <ivoks> you can paste it to a file and upload it somewhere
[09:47] <Petaris> :)
[09:47] <ivoks> ok, sec...
[09:48] <ivoks> this looks ok
[09:49] <Petaris> what next then
[09:49] <ivoks> netstat -a | grep -v unix
[09:51] <ivoks> hm...
[09:51] <ivoks> didn't you say you booted clients?
[09:51] <Petaris> just one
[09:51] <ivoks> none is connected
[09:51] <Petaris> I'm not logged into it
[09:51] <Petaris> could that be why?
[09:52] <ivoks> ok, never mind...
[09:52] <ivoks> and memory is mostly free?
[09:52] <ivoks> free -m
[09:52] <Petaris> root@Ayumi:/var/log# free -m
[09:52] <Petaris>              total       used       free     shared    buffers     cached

[09:54] <Petaris> easier to read: http://phpfi.com/115939
[09:55] <ivoks> hm...
[09:55] <ivoks> just a sec...
[09:55] <Petaris> ok
[09:56] <ivoks> install and run saidar package
[09:57] <ivoks> and take a look at disk activity
[09:57] <Petaris> ok, sec
[10:05] <ivoks> anything abnormal?
[10:09] <Petaris> other then I'm still waiting for it to finish installing?
[10:09] <ivoks> :)
[10:09] <Petaris> :/
[10:09] <ivoks> ok...
[10:10] <ivoks> in grub
[10:10] <ivoks> add this argument to kernel:
[10:10] <ivoks> elevator=cfq
[10:14] <Petaris> add it at the end of that line?
[10:15] <ivoks> yes... kernel .... elevator=cfq
[10:15] <Petaris> added
[10:15] <ivoks> now boot that kernel
[10:15] <Petaris> ok
[10:17] <Petaris> what will that do
[10:18] <ivoks> change default io scheduler
[10:18] <ivoks> from deadline to cfq
[10:19] <ivoks> in -686 and -386 default if anticipatory
[10:19] <ivoks> and in -server deadline
[10:19] <ivoks> this is kernel tuning
[10:21] <Petaris> ok its back up
[10:21] <ivoks> it's not cpu, it's not memory, nor network
[10:21] <ivoks> so, it has to be disk :)
[10:21] <Petaris> and I was able to install saidar
[10:22] <ivoks> is it slow again?
[10:22] <Petaris> yeah, but not quite as slow
[10:23] <Petaris> http://phpfi.com/115945
[10:23] <ivoks> faster than before?
[10:23] <ivoks> but still slow
[10:23] <Petaris> yes, but not by much
[10:23] <ivoks> this comp is totally idle
[10:24] <Petaris> yeah
[10:24] <Petaris> not even a client booted yet
[10:24] <Petaris> sda is getting a writes every few secounds
[10:25] <ivoks> i guess these are nfs exports?
[10:25] <ivoks> on sda
[10:25] <Petaris> not sure
[10:26] <ivoks> i'm missing something :)
[10:26] <Petaris> me too
[10:27] <ivoks> ok, try booting with elevator=anticipatory
[10:27] <ivoks> (this is a long shot)
[10:28] <Petaris> ok, rebooting
[10:30] <Petaris> ok its up
[10:31] <ivoks> and?
[10:31] <Petaris> wth?
[10:31] <Petaris> I can't ssh to it
[10:31] <Petaris> ahh, there it goes
[10:31] <ivoks> ?
[10:32] <Petaris> still very slow
[10:33] <ivoks> ok
[10:33] <ivoks> then it's memory
[10:33] <Petaris> espeacially with X stuff
[10:33] <ivoks> X stuff?
[10:33] <ivoks> on clients?
[10:33] <Petaris> on the server
[10:33] <Petaris> I haven't booted the client yet
[10:33] <ivoks> hm...
[10:34] <Petaris> maybe it is an xorg issue
[10:34] <Petaris> naw
[10:34] <Petaris> that would show in memmory probably
[10:34] <ivoks> well, -server doesn't have preempt
[10:35] <Petaris> hrm
[10:35] <Petaris> is there anyway to add it?
[10:35] <Petaris> like as a kernel option?
[10:35] <ivoks> nope
[10:35] <Petaris> bugger
[10:35] <ivoks> pardon
[10:35] <ivoks> it has preempt
[10:36] <Petaris> oh
[10:36] <Petaris> then thats not it
[10:36] <ivoks> CONFIG_PREEMPT_NONE=y
[10:36] <Petaris> hrm
[10:37] <ivoks> # CONFIG_PREEMPT is not set
[10:37] <Petaris> should it be?
[10:37] <Petaris> *for an ltsp server
[10:38] <ivoks> well, i'm not sure it's preempt problem
[10:38] <ivoks> BenC will know that better
[10:38] <ivoks> i'm really not sure
[10:39] <ivoks> anyway, report a bug
[10:39] <Petaris> hrm
[10:39] <Petaris> This is not good
[10:40] <Petaris> maybe I should just build my own kernel
[10:40] <Petaris> off of the i386 one that worked
[10:40] <ivoks> you can try with .config of -server
[10:40] <ivoks> but change preempt
[10:41] <Petaris> and add the smp and support for greater than 4 GB of RAM
[10:41] <ivoks> and then you'll know if it is preempt
[10:41] <Petaris> hrm
[10:41] <ivoks> all kernels are i386
[10:41] <ivoks> but one is -686
[10:41] <Petaris> the i386 kernel (not server) worked quite well for me
[10:42] <Petaris> but with only one cpu and 4 GB of ram
[10:42] <ivoks> -386 kernel is generic
[10:42] <ivoks> use -686
[10:42] <Petaris> hrm
[10:43] <ivoks> did you file a bug about this?
[10:43] <Petaris> no
[10:43] <Petaris> not sure what to put in it
[10:43] <Petaris> My system is slow? lol
[10:43] <ivoks> poor performance with -server kernel on ltsp server
[10:44] <ivoks> and mention that X apps are slow
[10:45] <ivoks> or all apps are slow?
[10:45] <Petaris> cli apps are slow as well, but not nearly as slow as X apps are
[10:45] <ivoks> i doubt that's preempt
[10:46] <ivoks> well... build your own kernel
[10:46] <ivoks> and you'll see how it goes, but file that bug
[10:46] <Petaris> is there anything speacial I have to do when building it?
[10:47] <ivoks> get source
[10:47] <ivoks> and copy /boot/config*-686 in .config
[10:47] <ivoks> change max ram supported and that's it
[10:47] <Petaris> I don't have a 686 config
[10:48] <ivoks> wait...
[10:48] <ivoks> is that 32bit or 64bit? :)
[10:48] <ivoks> processor
[10:49] <Petaris> opterons are 64 bit with 32 bit compatability
[10:49] <Petaris> I run 32 bit on them
[10:49] <ivoks> that's why -386 works
[10:49] <ivoks> -686 wouldn't work either
[10:50] <ivoks> get amd64 release
[10:50] <ivoks> not i386
[10:50] <Petaris> won't that break my ltsp clients?
[10:50] <Petaris> well worth a try
[10:50] <ivoks> break? why?
[10:51] <Petaris> 64 bit server enviornment with 32 bit clients?
[10:52] <Petaris> hrm
[10:52] <Petaris> where is the amd64 linux-image?
[10:52] <Petaris> I can only find the k7
[10:52] <ivoks> on amd64 cd
[10:52] <Petaris> hrm
[10:52] <ivoks> together with amd64 libc :)
[10:52] <Petaris> right
[10:53] <Petaris> I was recommended not to run that for ltsp server
[10:53] <ivoks> why?
[10:53] <Petaris> issues with clients and some of the other software
[10:54] <Petaris> ogra in #edubuntu was the one who advised that
[10:54] <ivoks> thath could be, i don't know
[10:54] <ivoks> then you have to use -386 kernel
[10:55] <Petaris> right
[10:55] <ivoks> not -686
[10:56] <Petaris> is there a specific source package I should use?
[10:56] <Petaris> and is there anything speacial I have to do when building it?
[10:56] <ivoks> apt-get install linux-source
[10:56] <Petaris> ok
[10:57] <Petaris> brb
[10:59] <Petaris> back
[11:02] <Petaris> ok, its installed
[11:02] <ivoks> you'll find the source in /usr/src
[11:03] <Petaris> ok
[11:03] <ivoks> you know how to compile a kernel?
[11:03] <Petaris> yeah
[11:03] <ivoks> great
[11:03] <Petaris> but is there anything speacial I need to know?
[11:04] <ivoks> nope...
[11:04] <ivoks> go in /usr/src/linux-...
[11:04] <ivoks> copy /boot/config*-386 in .confg
[11:04] <ivoks> .config
[11:04] <ivoks> starta make menuconfig
[11:04] <ivoks> add support for 16GB RAM
[11:04] <ivoks> and build it with make
[11:05] <Petaris> how do you create that initrd.img file in /boot
[11:06] <nawty> Hey folks, anyone round here had any experience with the Adaptec/Intel/IBM SATA HostRAid ?
[11:06] <ivoks> mkinitramfs -o /boot/my_new_initrd
[11:08] <Petaris> ivoks: don't I have to do a make old-config or something?
[11:09] <ivoks> no
[11:09] <ivoks> just run make
[11:09] <Petaris> oh
[11:09] <Petaris> I seem to remember having to do that before
[11:10] <ivoks> you runed make menuconfig
[11:10] <ivoks> and changed a configuration
[11:11] <ivoks> so oldconfig is newconfig now :)
[11:11] <Petaris> ahh
[11:11] <Petaris> ok
[11:16] <Petaris> hrm
[11:16] <Petaris> root@Ayumi:/usr/src/linux# make menuconfig
[11:16] <Petaris> -bash: make: command not found
[11:16] <Petaris> that can't be good
[11:16] <ivoks> apt-get install build-essential
[11:16] <Petaris> ok
[11:16] <ivoks> i have to go now...
[11:17] <Petaris> alright
[11:17] <Petaris> thanks for all the help
[11:17] <ivoks> i hope it will work
[11:17] <Petaris> me too
[11:17] <ivoks> read some docs about initrd
[11:17] <ivoks> i'm not sure if it will work as i said
[11:17] <Petaris> ok
[11:17] <ivoks> bye
[11:17] <Petaris> bye
[11:23] <Petaris> hrm
[11:35] <nawty> anyone?
[11:35] <Petaris> nawty: LSI MegaRAID SATA
[11:35] <Petaris> but none of the ones you listed
[11:36] <nawty> :(
