[01:16] <level15_> hi, all. I am having massive kernel errors on my linux guests when my host has intensive I/O usage (VM images backup operations). Sometimes, the guest kernel will remount the fs in read only mode, which obviously crashes most of my services. I have been reading and have found that this might be related to host I/O cache, and that it might be a good idea to turn it off by settiong cache=none for all disks of my guests. Is that safe in case of a
[01:16] <level15_> host failure?  Has anyone had the same issue and, if so, how did you solve it? Thanks.
[01:19] <SpamapS> level15_: cache=none is safe, yes.
[01:19] <level15_> SpamapS: thanks
[01:19] <SpamapS> level15_: it may result in slower burst I/O speeds, but thats whats killing you now anyway (lots of bursts that hammer the cache)
[01:19] <sarnold> level15_: that somehow reminds me of https://bugs.launchpad.net/bugs/1064521
[01:21] <level15_> reading...
[01:21] <SpamapS> sarnold: that looks AIO related
[01:22] <level15_> I also read something about setting AIO to threads
[01:22] <sarnold> SpamapS: oh? I may have missed that...
[01:22] <level15_> in KVM
[01:22] <sarnold> SpamapS: does kvm do AIO or async io or mmap or blocking ..?
[01:23] <SpamapS> I don't think it goes through user space..
[01:23] <level15_> the bug report suggest changing the i/o scheduler... that would be on the host, not the guests, correct? And for that to work, I would need to reboot the host. Correct?
[01:23] <SpamapS> sarnold: I don't know enough to answer intelligently tho
[01:24] <SpamapS> looks like you have to pass aio=native to turn on AIO
[01:25] <SpamapS> level15_: no not correct
[01:25] <level15_> I read threads was better than native
[01:25] <SpamapS> level15_: http://www.cyberciti.biz/faq/linux-change-io-scheduler-for-harddisk/
[01:25] <sarnold> SpamapS: drat :)
[01:25] <level15_> SpamapS: good! thanks!
[01:26] <SpamapS> level15_: http://publib.boulder.ibm.com/infocenter/lnxinfo/v3r0m0/index.jsp?topic=%2Fliaat%2Fliaatbpkvmasynchio.htm
[01:26] <SpamapS> level15_: no hard data there, but "tests show it improves thigns" blah blah
[01:31] <level15_> SpamapS: So i should use a raw device instead of files... I would have liked to know that before i set up my VMs :-S
[01:42] <SpamapS> level15_: thats a pretty common paradigm. Files are only for convenience
[01:48] <sarnold> but man they are convenient. :)
[03:23] <level15_> thanks for your help earlier today.
[03:33] <trimeta> I run a home server, which gives me the landscape-based system info whenever I log in. I like this, but I'd like to configure exactly what landscape shows, rather than just seeing the default info. Is there a way to find a sample /etc/landscape/client.conf (or even a landscape-sysinfo man page) without installing the full landscape-client package which doesn't make any sense with a single-server setup? (E.g., a setup wh
[03:34] <trimeta> Hmm, aptitude show suggests that landscape-client is more about integrating with Ubuntu's cloud infrastructure. I don't want that either; I'm happy to just ssh into my own server. I'd just like to configure what appears when I do so.
[03:42] <tedski> I'm trying to get 12.04 ready for production to migrate our systems off lucid... we use nis netgroups in ldap and i'm noticing a bug in libpam-modules (pam_access.so specifically) 1.1.3-7ubuntu3.  I read that this is fixed in > 1.1.3 but I notice quetzal still has 1.1.3.  I tried quetzal's build anyway, but to no avail.  If i bring in pam_access.so from a 1.1.1 machine (lucid has 1.1.1), it works fine.  What is my best course of action at this point?
[03:42] <tedski> should I build my own package using pam 1.1.5?
[03:42] <tedski> should I roll all systems back to lucid's working version of libpam-modules?
[03:43] <tedski> or is there a more sane way to get an updated version of libpam-modules?
[03:47] <ReekenX> tedski: First question: is mirgration really important or it can just wait?
[03:47] <tedski> it's important
[03:47] <tedski> and a coworker may or may not have already allowed a few precise boxes in prod :(
[03:48] <tedski> hence my penchant for a shitty workaround
[03:50] <ReekenX> Well I don't know maybe others have different opinion, but in your place I would just build my own package and when apt repositories will update you will receive developers build package.
[03:50] <ScottK> tedski: If you can find the exact change from upstream that fixed it, we can get a post-release update done, but in the meantime, if you've tested bringing the lucid package forward and it works in your use case, it's not insane.
[03:51] <tedski> ScottK: yeah, i haven't tested the whole package, just pam_access.so
[03:52] <tedski> ScottK: i'll see if i can find the change in the upstream release
[03:52] <tedski> ReekenX: thanks for the advice, that's what i'll do in the meantime
[04:33] <tedski> hrmm... okay... so it is fixed in Linux-PAM-1.1.5 and the fix is somewhere in here http://paste.ubuntu.com/1286316/
[04:33] <tedski> i'll poke at it a bit more tomorrow and nail down the exact fix
[04:37] <SpamapS> Man, I used to think NIS was dead
[04:37] <tedski> heh
[04:37] <SpamapS> but the number of bug reports I see about it make me think twice
[04:38] <SpamapS> I mean, it is walking dead, no doubt
[04:38] <tedski> it is
[04:38] <tedski> and this is nis migrated to ldap
[04:38] <tedski> yay for legacy
[04:40] <ScottK> tedski: Once you get it nailed down, file a bug with the patch and steps for reproducing the issue.  Then give me a ping with the bug number and I"ll look at getting it in.
[04:40] <tedski> ScottK: sweet.. thanks, will do

[08:43] <chovynz> how do I make functions and where are they stored?
[08:48] <melmoth> chovynz, what do you mean by functions ?
[08:50] <chovynz> alias wouldthiswork='find ~ -name "* *" -type f && $(($(find ~ -name "* *" -type f | wc -l -printf 1+)0))'                 what im trying to do, is list all files that have spaces, then number them. I currently have success. But I want to pass the result of the second find to a variable so I can say echo there are <variable> files that have spaces. Someone suggested I use functions instead of alias
[08:50] <melmoth> http://tldp.org/HOWTO/Bash-Prog-Intro-HOWTO-8.html
[08:52] <chovynz> melmoth: where does the function go? in bashrc or in .bash_aliases ?
[08:53] <melmoth> .bashrc i think
[08:53] <melmoth> or any file you source before calling it
[08:54] <chovynz> .bash_aliases is being sourced anyway, so could I continue to use that but with a function inside, instead of an alias?
[08:57] <melmoth> try :)
[08:57] <chovynz> lol
[09:08] <chovynz> melmoth: -bash: /home/nathaniel/.bash_aliases: line 1: syntax error near unexpected token `(' -bash: /home/nathaniel/.bash_aliases: line 1: `spacef() {'      what am i doing wrong? http://paste.ubuntu.com/1286580/
[09:08] <chovynz> oops
[09:09] <melmoth> works here
[09:10] <chovynz> how do you get it to work?
[09:10] <melmoth> i mean i just pasted the function ina file, sourced it and launched spacef
[09:10] <chovynz> whats the output?
[09:11] <melmoth> http://pastebin.ubuntu.com/1286581/
[09:11] <melmoth> it s still running :)
[09:11] <melmoth> i m not sure about what the find is doing
[09:11] <melmoth> but i can call the function all right
[09:12] <melmoth> well, it show the number of file but $spacef is not correctly set
[09:12] <melmoth> it s actually.. not set at all
[09:12] <chovynz> the find is trying to find all files with a space in it,
[09:12] <chovynz> how do i set it lol
[09:13] <melmoth> http://pastebin.ubuntu.com/1286585/
[09:14] <chovynz> ah
[09:15] <chovynz> $me=dumby. echo chovynz is $me
[09:18] <chovynz> melmoth: i would kiss you even if you were a hedgehog
[09:18] <chovynz> thank you very much

[10:48] <pitti> hello everyone
[10:48] <pitti> I've got a question aboutu charms again
[10:48] <pitti> I checked out jibel's jhbuild charm and was making some edits to it, in particular hooks/install
[10:49] <pitti> (locally, nothing committed to LP)
[10:49] <pitti> I run this as "juju deploy --repository ~/ubuntu/charms local:jhbuild jhbuild-test"
[10:49] <pitti> shoudl this use the actual files in ~/ubuntu/charms/quantal/jhbuild/* ?
[10:50] <pitti> because every time I do this, the thing that lands in the newly created VMs is the old version without my changes
[10:59] <pitti> what does seem to help is to run upgrade-charm afterwards
[10:59] <pitti> I even bumped revision, but it still seems to deploy revision 1
[10:59] <pitti> is that cached somewhere?
[11:04] <melmoth> pitti, i think you need to increment your charm revision file
[11:04] <pitti> that's what I tried after the first failed attempt
[11:04] <pitti> but after bumping it still deployed versino 1
[11:04] <pitti> I now destroyed teh whole env and re-bootstrapping
[11:05] <pitti> melmoth: where in the stack does it cache the old revisions?
[11:05] <melmoth> i have no idea
[11:05]  * melmoth is a juju n00b
[11:05] <pitti> ok, thanks
[11:06] <pitti> destroying env & re-bootstrap helped
[11:07] <pitti> but that can't be the final answer

[13:38] <ubsrv> hi, trying to install a packet using ppa geting this probleme , http://pastebin.com/YJFSsWuV
[13:39] <TLoT> is that a private PPA?
[13:40] <TLoT> i'm assuming so since the team its connected to doesnt show for normal people
[13:40] <ubsrv> its open bravo comunity edition for ubuntu servers
[13:41] <TLoT> ubsrv: you sure that ppa link is right?
[13:41] <TLoT> the format returns a 404 when i convert it to its LP link
[13:41] <ubsrv> yes right !
[13:42] <subman> I'm installing Ubuntu Server for the first time and it seems to have stalled after successfully configuring the network.  No error, just a purple screen.
[13:43] <tedski> ubsrv: according to open bravo's documentation... you're using the wrong ppa
[13:43] <TLoT> ubsrv: nnnope.  https://launchpad.net/~openbravoisv fails.  try using ppa:openbravo-isv/ppa instead
[13:43] <tedski> add-apt-repository ppa:openbravo-isv/ppa
[13:43] <TLoT> and you're probably using the wrong ppa if you're using the wrong link
[13:43] <TLoT> which i said already, your link was likely wrong.
[13:43] <tedski> that's from http://wiki.openbravo.com/wiki/Installation/Ubuntu

[17:17] <alysur> hey
[17:17] <alysur> Can someone point me to a channel to help with website troubles running LAMP on ubuntu server?
[17:24] <TheInfinity> heyho
[17:25] <TheInfinity> i have a 64bit system with a cups printing server (via samba). i just upgraded from 10.04 to 12.04. now my 32bit printer driver does not work any more.
[17:25] <TheInfinity> what would be the best way to get it back working (and btw - why did just force install work before - and now it fails?)
[17:26] <RoyK> it fails if there are dependencies that can't be resolved
[17:26] <RoyK> please pastebin errors
[17:27] <TheInfinity> RoyK: just force install results into a dependency problem and into non working filters
[17:28] <TheInfinity> which is trange, in 10.04 everything was ok, also the filters (/usr/lib/cups/filter/
[17:31] <alysur> there can be problems upgrading versions, what method did you use?
[17:31] <TheInfinity> do-system-upgrade
[17:32] <RoyK> or do-release-upgrade
[17:32] <TheInfinity> yea i meant this ;)
[17:32] <TheInfinity> http://pastebin.com/GSTDBruY
[17:33] <alysur> ok good
[17:34] <alysur> lol thats about all i know about upgrading with minimal problems
[17:34] <alysur> still learning what i can.
[17:35] <TheInfinity> alysur: eben zimbra was no problem. upgrade was really, really smoth (when i remember dapper ... huh!). but this printer driver ... huh. -.-
[17:35] <TheInfinity> *even
[17:35] <alysur> anyone able to point me to a channel more appropriate for php parsing problems?
[17:36] <alysur> I often just backup necesary files and then do fresh installs of ubuntu and then reload the data i need back onto the machine, i view it as a safer method
[17:36] <RoyK> TheInfinity: I'd say file a bug, but please set LC_ALL=C before filing it, since not all people understands German ;)
[17:36] <alysur> might just be paranoid though +P
[17:37] <alysur> ich verstehe nicht
[17:38] <TheInfinity> RoyK: the deb is a i386 deb ... which is the problem at all. the main problem is - what's the right way to use 32bit printer drivers in 64bit systems?
[17:38] <sarnold> warum nicht? :)
[17:38] <RoyK> TheInfinity: there seems to be conflicts between libs
[17:39] <alysur> running a 64bit version?
[17:39]  * TheInfinity runs a 64 bit server, yea
[17:39] <alysur> I had problems that i was directed to make sure i downloaded the 32bit libraries
[17:39] <RoyK> does anyone run 32bit OSes anymore? ;)
[17:39] <TheInfinity> RoyK: ... at a server? ;=
[17:39] <alysur> i do, on 32 bit systems =P
[17:39] <RoyK> well, not much choice
[17:40]  * RoyK only has a couple of ARM machines on 32bit
[17:40] <alysur> not a server, that was a desktop enviornment, but i remember having troubles running 32bit applications on a 64bit version
[17:41] <RoyK> alysur: afaics this isn't a 32/64bit problem, but a problem with older libs installed than what's needed
[17:42] <alysur> alrighty, i never did get the 32bit apps running . not really relavent here though
[17:42] <TheInfinity> ok that's scary. first time i tried apt-get -f install's only sollution was to uninstall my driver package. now - i do not think i changed anything - it provides an solution which installs several i386 libs
[17:42] <TheInfinity> wtf Oo
[17:42] <TheInfinity> i dont like different behaviour at same request.
[17:42] <sarnold> TheInfinity: there were a few hours yesterday with busted mirrors; did you perhaps get the "remove" option during those hours?
[17:43] <TheInfinity> sarnold: everything yesterday
[17:43] <TheInfinity> *today
[17:43] <TheInfinity> in the last 6 houres
[17:43] <sarnold> ah, then ignore me again ;)
[17:43] <alysur> ill be back in a short bit here
[17:43] <TheInfinity> sarnold: but thanks, such "minor" issues often have quite unhealthy results :)
[17:44] <sarnold> TheInfinity: yes, I spent half an hour investigating my own local system before questioning the mirrors... hehe.
[17:50] <RoyK> http://www.ubuntu.com/ <-- :D
[17:57] <TheInfinity> wow
[17:57] <TheInfinity> this seems to work
[17:57] <TheInfinity> i have _no_ idea how ubuntu decides that this specific cups filters have to be run in 32bit mode
[17:58] <sarnold> TheInfinity: was the filter produced by xerox or something, and just provided as a binary blob?
[17:58] <TheInfinity> and i habe also no idea why ubuntu offered me this time the 32bit lib solution
[17:59] <TheInfinity> sarnold: binary blob, it's a dell printer which seems to be a relabled fuji xerox
[17:59] <sarnold> hahaha
[17:59] <sarnold> how's that for confusing? :()
[17:59] <sarnold> :)
[18:00] <TheInfinity> i have _no_ idea what dell, xerox and fuji had in mind when they developed this. i hope nothing. i'm afraid it's pure sadism -.-
[18:13] <patdk-wk> well, dell doesn't make anything, it's all rebranded stuff
[18:14] <patdk-wk> well, I guess the do make their motherboards, or have them made for them
[18:22] <RoyK> patdk-wk: Dell has bought a few companies over the time, and thus are making their own things more and more
[18:22] <RoyK> such as EqualLogic SANs
[18:22] <patdk-wk> ya, that is the only oneI can think of
[18:22] <RoyK> which I have begun to get a rather bad feeling about
[18:22] <RoyK> no checksumming, just trusting drives' ECC
[18:22] <RoyK> bad indeed
[18:23] <RoyK> the chance for a checksum collision on most drives are low, said to be 1:10^14 or 1:10^15, in practice perhaps 1:10^12
[18:24] <RoyK> still a high number, unless you have a truckload of drives
[18:24] <RoyK> better use something sane like ZFS :þ
[18:49] <l0p3n> Hello! I am trying to load ubuntu-server iso from grub but I am failing. Could someone please take a look at the commands I'm using and tell me what I'm doing wrong?  http://pastebin.com/4NTFqexJ
[18:55] <sarnold> l0p3n: perhaps a forgotten 'insmod fat'?
[18:55] <sarnold> l0p3n: you also have hyphens before noprompt and noeject -- is that intentional? (unlikely to be related)
[19:00] <TheInfinity> thanks for everything, especially @ RoyK :)
[19:01] <RoyK> :)
[19:07] <l0p3n> sarnold: Oh I see that now. But I did use --noeject and --noprompt in grub. And I have also tried using insmod fat.
[19:09] <l0p3n> sarnold: When I followed the steps in the tutorial using an Ubuntu-desktop image I had no problems booting the image. I just can't understand why I can't do the same thing with a ubuntu-server-image :/
[20:37] <Sentynel> hi folks, just upgraded my ec2 server to 12.10 and it won't boot. I suspect grub is broken; the server starts up but fails EC2's reachability check, and nothing is getting written to /var/log/boot* or anything. I've got the root volume mounted to another ec2 server and chrooted in, but running grub-install fails saying "path /boot/grub is not readable by grub on boot."
[20:38] <Sentynel> I also tried just running update-grub, which ran with no complaints but didn't make any difference
[20:38] <Sentynel> any suggestions?
[20:48] <hallyn> Sentynel: is /boot a different drive?  did you mount it?  any errors upon mounting?  any drives full by chance?
[20:49] <Sentynel> hallyn: no, single volume. I mounted it and chrooted in. there's plenty of space on the drive.
[20:49] <RoyK> call amazon
[21:11] <patdk-lap> hmm, the drive was setup at sector 2048 or higher right?
[21:11] <Sentynel> whatever the amazon defaults are
[21:11] <patdk-lap> I know many people where having issues cause grub breaks the 32k limit now
[21:11] <Sentynel> it's worked fine for the last year and two upgrades
[21:11] <patdk-lap> yes, but you said you upgraded
[21:11] <Sentynel> hrm
[21:11] <patdk-lap> and upgrade from what install would matter
[21:11] <Sentynel> it was originally 11.04
[21:12] <patdk-lap> so it should be, but I can't confirm
[21:28] <chovynz> I have a bunch of music on my server, what can I use to get them served? currently I can access them via http, but that's clunky. What program (on both ends), one that serves, and one that controls or can make their own playlist independantly of other computers?

[22:04] <paco1> im creating a dns test server with ubuntu server 12.04. I have problems with the new resolvconf configuration. In fact, with ubuntu server 10.04, with the same configs dns files, all works fine
[22:09] <paco1> and i think the problem is resolvconf
[22:10] <paco1> i don't know really how to setup it, meanwhile there are a lot of documentations
[22:13] <paco1> for exemple, what is the difference between dns-search and dns-nameservers in /etc/network/interfaces and search and namserver in /etc/resolvconf/resolv.conf.d/base?
