Device Labels being lost in CENTOS 4.4?
by Dr R L Oswald 18 Apr '07

18 Apr '07

We have run CENTOS 3.x on a large number of machines used for technical computations, both 32/64-bit servers and 32-bit dual-boot desktops, with no issues whatsoever over a long period of time. We have since upgraded the servers to CENTOS 4.4 but a small number of dual-boot desktops which have been created recently using CENTOS 4.4/XP have very rapidly started to exhibit this symptom: The dual-booting (GRUB is the 1Y bootloader) works OK for a while but then on a subsequent reboot from Windows to CENTOS, the boot halts in GRUB with an error message that mkdevlabel could not see label "/1" i.e. the root partition. The fix we adopted was to convert the LABEL references in grub.conf and /etc/fstab to use the "traditional" real device names not the symbolic links pointed to by the LABELs. I do not think that there is any option in the installer to avoid using device labels for partitions ? Trawling on Google shows others have seen similar issues with other distros based on RHEL4 - has anyone seen this with CENTOS, know why it happens and if it can be avoided? Certainly, fixing it is tedious as you have to boot from CD, then replace the two affected files above, so any suggestion that avoids this issue would be much appreciated before we attempt to migrate our desktops to CENTOS 4.4 FYI the PCs concerned have Intel 945 motherboards and SATA drives.

Centos 4 software raid issue

i need to remove a software raid 1 form my system. I have yet to find a way that applies to 2.6x kernels. I know the information is out there. Would anyone care to give me a pointer?

XEmacs on CentOS 5
by bgschaid_lists＠ice-sf.at 18 Apr '07

18 Apr '07

Either I'm having a case of "now you see it, now you don't" or I'm just plain stupid: When upgrading one of my 4.4-machines I discovered, that XEmacs (my text editor of choice; please no religious discussions) isn't part of the distribution anymore. OK. I progressed without it (and removed the old xemacs-packages because they were not working anymore). Then I installed the rpmforge-release and some yum-extensions (fastest mirror, protect and priority). Then I went to yumex. Looked for "emacs" and voila: the xemacs packages were there. So I installed them and they worked. I went to the next machine, started to upgrade it. When I tried to install xemacs I could not find it. Going back to the first machine I could not find those xemacs packages I didn't install (xemacs-el) and I don't dare to deinstall (and then reinstall) xemacs for fear I might never find it again. Does anyone have an idea where the package could be from (I have appended the header from "rpm -qi xemacs"? I think I remember, that when I installed it it said "base" Could it have to do with the fastest-mirror-plugin? Is there a way to find out which mirror yum is actually using? Name : xemacs Relocations: (not relocatable) Version : 21.4.15 Vendor: CentOS Release : 10.EL.1 Build Date: Fri 18 Feb 2005 06:16:19 AM CET Install Date: Mon 16 Apr 2007 05:25:46 PM CEST Build Host: x8664-build Group : Applications/Editors Source RPM: xemacs-21.4.15-10.EL.1.src.rpm Size : 8276569 License: GPL Signature : DSA/SHA1, Sat 05 Mar 2005 05:52:52 PM CET, Key ID a53d0bab443e1821 URL : http://www.xemacs.org/ Summary : A different version of Emacs.

Custom CentOS5 DVD
by Paul 18 Apr '07

18 Apr '07

Hello, Does anyone have an up-to-date page describing, step by step, how to make a customized CentOS5 DVD? I noticed that CentOS5 already comes with ~240MB of updates. So for starters, I'd like to create a new DVD with all the current updates. (And I have other custom scripts I need to install on top of that). I've googled around and tried various suggestions on the net: http://sipx-wiki.calivia.com/index.php/A_Kickstart_CD_for_sipX_on_CentOS http://cablemodem.fibertel.com.ar/lateral/stories/38.html However, I have not been able to find step by step instructions for CentOS5. For example, genhdlist has been deprecated. Also, the centos-release-5.0.0 rpm grabs a new GPG key from the net, even though an identical one is already on the DVD. This creates problems on custom DVD's I've created thus far; I'd like to have an unattended install that doesn't require a network connection. Thanks very much in advance for your help, -- Paul

Jigdoes of CentOS 4.4 and 5.0 i386/x86_64 CD/DVD available.
by Maciej Zenczykowski 18 Apr '07

18 Apr '07

I've gone through the trouble (after some 10 rounds I finally have something I'm happy with) and generated jigdo/template files for CentOS 5.0 iso's (CD/DVD i386/x86_64) (and CentOS 4.4 while I was at it: CD/DVD/ServerCD SRPMS/i386/x86_64). (and I started on this before the thread about creating the DVD's from the CD's started ;-) ) They are available at: http://tcs.uj.edu.pl/~buildcentos/centos-jigdo/ (I skipped the LiveCD since jigdo offers no size improvement here -- already for the ServerCD the template file is 125 MBs because of the different .img files inside the iso) These jigdo/template files should allow you to generate any of the listed cd/dvd isos from the publically available http://mirror.centos.org mirror site (which is DNS-aliased to something close to you). Jigdo will also allow using a local source of files (ie. an existing CD, etc...) You will need to install jigdo-file and jigdo-lite. It is available: - in package jigdo from dag's repository (rpmforge) for CentOS 4 (and others) - in package jigdo-file for debian/ubuntu (just apt-get it) - from the source website (both sources, and windows binaries, and statically linked linux binaries) http://atterer.net/jigdo/ Once installed usage is (...should be...) trivial: jigdo-lite --noask http://tcs.uj.edu.pl/~buildcentos/centos-jigdo/%.jigdo which will generate the requested (replace the % with what you want, see the http://tcs.uj.edu.pl/~buildcentos/centos-jigdo/ listing) iso file in the directory in which you run it. [If you have a local source of files you can skip the --noask and provide it when asked] Next step: get this included on the centos mirrors ;-) [hint hint] Afterwards: it would be nice to drop the iso files from the mirrors in their entirety and generate them on-the-fly using the JTE extensions package. Should be significant space-savings. [requires perl cgi in the hosting webserver, but should be very safe since it's all read-only access] Even later: it would be awesome if we could generate the jigdo/template during mkisofs (requires using a patched mkisofs). This would skip the slightly painful jigdo generation step (painful - because I have to download a local mirror of both the files and the CD/DVD images, much less painful to do it directly on the centos source/build system/mirrors) Both later steps are 95% there (the JTE jigit website/extensions/mkisofs patches/etc) and mostly require putting together rpms for EL4/5. (I'm going to be trying to put together a mkisofs-jte rpm which doesn't override the normal mkisofs rpm, but instead provides two files - /usr/bin/mkisofs-jte and it's manpage) This should also allow more customized images (like the rolled up updates) without increasing mirror space usage. Jigdo (combined with hardlinking identical files, which I believe is already done) should enable drastic reductions in centos HDD footprint. Comments? Cheers, Maciej Zenczykowski

mirror rsync problem?
by John R Pierce 18 Apr '07

18 Apr '07

I've got an intranet mirror of centos, been updating it periodically, recently my updates started failing... I've tried several different mirrors as sources, but each time, the update fails at some random point with this error... rsync: read error: Connection timed out (145) rsync error: error in rsync protocol data stream (code 12) at io.c(614) [receiver=2.6.8] rsync: connection unexpectedly closed (1605001 bytes received so far) [generator] rsync error: error in rsync protocol data stream (code 12) at io.c(463) [generator=2.6.8] per a bit of googling, it appears this may be a generic 2.6.8 error, as explained here... http://www.mail-archive.com/rsync@lists.samba.org/msg16205.html for what its worth, my local mirror server is actually a Sun ultrasparc running Solaris 10, with its built in rsync 2.6.8, which appears to be the same version as is running on the centos mirror servers.

I am installing CentOS5 on a dell Lattitude D610. dmesg: recognizes the the wireless Intel 2915: ipw2200: Detected Intel Pro/Wireless 2915ABG Network Connection I have googled for ipw2915 and centos5 OR rhel5, can't find instructions for installing the firmware. Should the firmware be installed from the CDs? Any suggestion? -- Thanks http://www.911networks.com When the network has to work
