[12:07] <uncledeath> Hi folks, I have a strange problem. I am upgrading my home server (Core2Duo E6600, 4GB DDR2, 2x 500GB SATA HDD). A few days ago I set it up with software raid and lvm and it worked fine until it started freezing on any IO related stuff. I have 0,1% CPU usage and loads greater than 10! If any disk operation occurs my system is inresponsive, it takes 5 minutes to log onto it.
[12:07] <uncledeath>  I am reinstalling my system for the 10-th time and still no success. Now it is stuck on "setting mdadm"
[12:08] <uncledeath> I can see that /proc/mdadm is showing resync
[12:08] <uncledeath> and what is strange is the fact, that if resync is the only disk job it works fast (calculated 1 hour for 500GB) but as soon as any other disk operation is in progress resync goes down to 5Kb/s and other disk operations are also 5-10 K/s
[12:09] <uncledeath> when that happens system is totally unresponsive, avarage load is more than 10 (core2duo) and cpu usage is less than 1%
[12:10] <uncledeath> I tried ubuntu server 12.10 64b, 12.10 32b and 12.04 32b
[12:10] <uncledeath> still the same
[12:11] <uncledeath> At this point installer gets stuck at configuring mdadm for long time
[12:12] <uncledeath> anyone?
[12:13] <uncledeath> I limited my raid to 20G and as soon as resync is complete system works again but it isn't as fast as it used to be a few days ago
[13:14] <railsraider> anyone using collectd?
[14:14] <pmatulis> hmmm, http://paste.ubuntu.com/1467219/
[15:03] <uncledeath> my ubuntu server installer takes forever at "configuring mdadm". CPU almost idle, system load very high and everything unresponsive. Any ideas?
[15:17] <pmatulis> uncledeath: during bootup you mean?
[18:37] <allSeeingEye> anyone here have the LPIC certs?
[19:02] <allSeeingEye> anyone in here think having LPIC certs are helpful to have on your resume?
[19:24] <pmatulis> allSeeingEye: certainly helpful, but by how much depends on the reader of the resume
[19:26] <pmatulis> allSeeingEye: when i help hire, it demonstrates to me the candidate has an eagerness/motivation to actually go through the process.  so to me, it's less a technical and more a personal merit
[19:28] <pmatulis> allSeeingEye: however, LPI3 is fairly technically-worthy i believe
[19:32] <LuizAngioletti> how do I find out which package provided a certain file?
[19:33] <TheLordOfTime> LuizAngioletti, sudo apt-get install apt-file
[19:33] <TheLordOfTime> sudo apt-file update
[19:33] <TheLordOfTime> apt-file search [file]
[19:33] <LuizAngioletti> TheLordOfTime: Thanks
[19:33] <TheLordOfTime> i think that's the full string of things.
[19:33] <TheLordOfTime> at least ofr updating apt-file, and installing it
[19:34] <TheLordOfTime> i rarely use apt-file so...
[19:34]  * TheLordOfTime isn't 100% certain
[19:36] <LuizAngioletti> TheLordOfTime: what do you use than?
[19:36] <LuizAngioletti> dpkg
[19:36] <LuizAngioletti> ?
[19:36] <LuizAngioletti> *then
[19:37] <pmatulis> looks good to me but no need to use sudo with 'apt-file update'.  i recommend a cron job for updating
[19:39] <LuizAngioletti> I know that for rpm packages there is some rpm-ish string to find file affiliations to packages... isn't there something dpkg-ish for that?
[19:43] <pmatulis> what is file affiliations?
[19:45] <TheLordOfTime> LuizAngioletti, usually i don't bother to care, because most of the core stuff I need i know where it came from, and only in very rare cases do i use apt-file
[19:45] <TheLordOfTime> (usually for package debugging)
[19:45] <LuizAngioletti> pmatulis: which package provides wich file.
[19:45] <TheLordOfTime> LuizAngioletti, what were you looking for?
[19:46] <LuizAngioletti> there is a binary called "daemon" under /usr/bin
[19:46] <LuizAngioletti> I want to know what it does. =)
[19:47] <LuizAngioletti> and maybe where I can find more info about it... it seems to be a wrapper for some operations, like 'start-stop' services...
[19:47] <LuizAngioletti> (I encountered reference to it in a script I'm reading)
[19:52] <pmatulis> LuizAngioletti: dpkg -S file
[19:52] <LuizAngioletti> pmatulis: that simply returns the name of the package, not something like package<version>.deb
[19:53] <LuizAngioletti> You see? I want to get what .deb gave me that file.
[19:53] <TheLordOfTime> LuizAngioletti, then use apt-file'
[19:53] <TheLordOfTime> which i just told you to do?
[19:53] <TheLordOfTime> apt-file search daemon
[19:53] <LuizAngioletti> I just found out what 'daemon' does, but now I'm curious about that now. =)
[19:53] <TheLordOfTime> and find the path in its output and then the first word(s) on the line are what package it comes from.
[19:54] <LuizAngioletti> TheLordOfTime: It helped me already. =)
[19:58] <allSeeingEye> pmatulis: do you have any LPI certs?
[19:58] <pmatulis> allSeeingEye: yes, levels 1 & 2
[19:59] <allSeeingEye> pmatulis: I'm working on 1. Did you use the practice exams at penguintutor.com to help?
[20:00] <allSeeingEye> I'm actually quite surprised at some of the questions. I've been managing linux systems for a few years now and it seems rather difficult to pass the practice exams @ penguintutor. I wonder how close they are to the actual exam.
[20:00] <pmatulis> allSeeingEye: no, just online info based on the outline given on the LPI site.  for me, 1 and 2 were pretty basic.  but you can be tripped up by inane questions
[20:01] <allSeeingEye> I'm hoping there aren't questions that have a potential of several answers, and you get it wrong b/c you don't answer it the way they want.
[20:01] <pmatulis> like multiple choice questions where each answer differs by a '.' or a '-'
[20:02] <allSeeingEye> are questions mostly multiple choice & true/false?
[20:02] <pmatulis> they are all multiple choice for 1 and 2 iirc.  things change though.  it was a few years ago
[20:03] <allSeeingEye> yeah
[20:06] <LuizAngioletti> I've done 101;]
[20:07] <LuizAngioletti> a few months back.
[20:07] <allSeeingEye> how was it LuizAngiloetti?
[20:07] <LuizAngioletti> Still multiple choice... and still some insane questions.
[20:07] <allSeeingEye> do you recall how many questions?
[20:08] <LuizAngioletti> I think that is described in the lpi.org page, isn't it?
[20:08] <allSeeingEye> probably, going to check
[20:41] <Feri_> Hi. Sometimes I need make a copy from a hard drive onto a new one. To do that I boot Knoppix live, make partitions in a new disk, format them, and copy all files with rsync. I can make the new disk bootable, but in the fstab I must change UUID lines manually. Is there a method what can do that automatically? Eg. change /dev/sda1 to UUID=...?
