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] I am reinstalling my system for the 10-th time and still no success. Now it is stuck on "setting mdadm" [12:08] I can see that /proc/mdadm is showing resync [12:08] 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] when that happens system is totally unresponsive, avarage load is more than 10 (core2duo) and cpu usage is less than 1% [12:10] I tried ubuntu server 12.10 64b, 12.10 32b and 12.04 32b [12:10] still the same [12:11] At this point installer gets stuck at configuring mdadm for long time [12:12] anyone? [12:13] 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] anyone using collectd? === Ursinha-afk is now known as Ursinha [14:14] hmmm, http://paste.ubuntu.com/1467219/ [15:03] my ubuntu server installer takes forever at "configuring mdadm". CPU almost idle, system load very high and everything unresponsive. Any ideas? [15:17] uncledeath: during bootup you mean? === Taftse is now known as Taftse|NL [18:37] anyone here have the LPIC certs? [19:02] anyone in here think having LPIC certs are helpful to have on your resume? [19:24] allSeeingEye: certainly helpful, but by how much depends on the reader of the resume [19:26] 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] allSeeingEye: however, LPI3 is fairly technically-worthy i believe [19:32] how do I find out which package provided a certain file? [19:33] LuizAngioletti, sudo apt-get install apt-file [19:33] sudo apt-file update [19:33] apt-file search [file] [19:33] TheLordOfTime: Thanks [19:33] i think that's the full string of things. [19:33] at least ofr updating apt-file, and installing it [19:34] i rarely use apt-file so... [19:34] * TheLordOfTime isn't 100% certain [19:36] TheLordOfTime: what do you use than? [19:36] dpkg [19:36] ? [19:36] *then [19:37] looks good to me but no need to use sudo with 'apt-file update'. i recommend a cron job for updating [19:39] 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] what is file affiliations? [19:45] 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] (usually for package debugging) [19:45] pmatulis: which package provides wich file. [19:45] LuizAngioletti, what were you looking for? [19:46] there is a binary called "daemon" under /usr/bin [19:46] I want to know what it does. =) [19:47] and maybe where I can find more info about it... it seems to be a wrapper for some operations, like 'start-stop' services... === cpg|away is now known as cpg [19:47] (I encountered reference to it in a script I'm reading) [19:52] LuizAngioletti: dpkg -S file [19:52] pmatulis: that simply returns the name of the package, not something like package.deb [19:53] You see? I want to get what .deb gave me that file. [19:53] LuizAngioletti, then use apt-file' [19:53] which i just told you to do? [19:53] apt-file search daemon [19:53] I just found out what 'daemon' does, but now I'm curious about that now. =) [19:53] and find the path in its output and then the first word(s) on the line are what package it comes from. [19:54] TheLordOfTime: It helped me already. =) [19:58] pmatulis: do you have any LPI certs? [19:58] allSeeingEye: yes, levels 1 & 2 [19:59] pmatulis: I'm working on 1. Did you use the practice exams at penguintutor.com to help? [20:00] 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] 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] 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] like multiple choice questions where each answer differs by a '.' or a '-' [20:02] are questions mostly multiple choice & true/false? [20:02] they are all multiple choice for 1 and 2 iirc. things change though. it was a few years ago [20:03] yeah [20:06] I've done 101;] [20:07] a few months back. [20:07] how was it LuizAngiloetti? [20:07] Still multiple choice... and still some insane questions. [20:07] do you recall how many questions? [20:08] I think that is described in the lpi.org page, isn't it? [20:08] probably, going to check === cpg is now known as cpg|away === JanC_ is now known as JanC === cpg|away is now known as cpg [20:41] 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=...? === guampa_ is now known as guampa === cpg is now known as cpg|away === fear is now known as Guest57020 === Guest57020 is now known as fihuer === cpg|away is now known as cpg
