time stray on the latest centos release: 2.6.9-11.EL
by Blair Lowe 13 Dec '06

13 Dec '06

Hi, The clock on my laptop seems to be straying dramatically from the real time even if I turn off ntpd. Could it be the clock applet itself? After I run rdate with ntpd off, it starts to stray right away. This started in the last two weeks after doing many updates. Has anyone else seen this, or even fixed it? Thanks in advance, Blair.

yum-utils-plugins and yum-utils
by Johnny Hughes 26 Nov '05

26 Nov '05

All, In an effort to better distribute files for our users, we have been working with some of the yum-utils-plugins from the yum website. Specifically, we have done some work with protectbase and fastestmirror. Here is the wiki concerning yum plugins: http://wiki.linux.duke.edu/YumPlugins We are currently testing these plugins, and they seem to work well. After a couple weeks of testing, we will move these into the main CentOS tree. Attached is the readme file for the new yum-utils-plugins RPM. If you want to test these plugins, they are currently in the dev.centos.org testing repo ... do this to test: 1. Download the file repo file and put it in /etc/yum.repos.d/ http://dev.centos.org/centos/4/CentOS-Testing.repo 2. Install yum-utils and yum-utils-plugins with this command: yum --enable=c4-testing install yum-utils yum-utils-plugins 3. Enable plugins in yum by editing the file /etc/yum.conf and adding this line: plugins=1 4. To use the protectbase plugin, edit your repos in /etc/yum.repo.d/ and add the following lines to repos you wish to protect (ie, the Official CentOS repos): protect=1 and add the following to third party (or other repos) which you want to use, but do not want to update/upgrade packages that are part of the protected repos: protect=0 see the attached readme file for an example. 5. To use the fastestmirror plugin, make sure you have the plugins=1 in /etc/yum.conf (see number 4. above) and then edit your /etc/yum.repos.d/ repos and add more than 1 mirror (as baseurl= ) for some of your repos ... see the attached readme file for some examples. Currently, the verbose setting is high for fastestmirror ... you may adjust that in /etc/yum/pluginconf.d/fastestmirror.conf. We will probably make this verbose=0 on final release. 6. There are other plugins that are not enabled by default .... you can see all the plugins in /usr/share/doc/yum-utils-0.3.1/plugins To enable a plugin that is not currently enabled, copy the .py file from it's directory to /usr/lib/yum-plugins/ and it's .conf file to /etc/yum/pluginconf.d/ (and make sure that /etc/yum.conf has a plugins=1 line in it) yum-utils is also installed. See the README in /usr/share/doc/yum- utils/ for all the commands you can do with yum-utils. ---------- Thanks, Johnny Hughes

Re: [CentOS-devel] New XFS code for the CentOS-4 Kernel from SGI

I would personally prefer if this XFS code could be merged into the CentOS Plus kernel. Having it as a separate RPM is a bit messy. If anyone is interested, I've done this and it's available as a patch to the existing kernel-2.6.9-22.0.1.106.unsupported.src.rpm via: http://home.btconnect.com/james/centos4/ BTW: what is the significance of '106' in the unsupported kernel name?

kernel-sourcecode RPM?
by Charlie Brady 22 Nov '05

22 Nov '05

I notice that CentOS 4.2 has no kernel-sourcecode RPM, unlike 4.0 and 4.1. Is that intentional or an oversight? --- Charlie

New XFS code for the CentOS-4 Kernel from SGI
by Johnny Hughes 22 Nov '05

22 Nov '05

The new XFS file system code from SGI is now available on the CentOS-4 Developer's testing site. You can install the dev-testing repo from here: http://dev.centos.org/centos/4/ And putting the CentOS-Testing.repo file in your /etc/yum.repo.d/ directory. You can then install the new xfs module on the standard centos i686 or x86_64 kernels. You have to pick the proper kernel that you are running. ------------------------------------------------------------------- Here is the command that would install the XFS module and the minimum required XFS tools: yum install dmapi xfsprogs xfsdump kernel-module-xfs-`uname -r`-0.1-1 -------------------------------------------------------------------- This will install the just released XFS code from SGI. BUT ... this code is still not 100% working with 4K stacks (which all EL 4 and FC 3/4/5 kernels currently use). A note from SGI on this code: ################################################################# # # # NOTICE # # This xfs module rpm has been provided for testing purposes # # only. It is believed to be functional, but it has not been # # heavily tested. In particular, you may have issues with the # # 4KSTACKS option on RHEL4 ia32 kernels, depending on your IO # # hardware, layering, nfs usage, etc. # # # # Please do NOT report any problems with this module, or with # # the kernel when this module is loaded, to Red Hat. # # You may report issues to the linux-xfs(a)oss.sgi.com list. # # (Please also report successes!) # # # ################################################################# You may also report successes and failures to the CentOS-Devel list. I installed this and ran 15 full tests with Bonnie++ on the XFS partition without any errors. I was using a PATA drive and a pIII 800 Mhz PC. ------------------------------------------------------ NOTE: This will not run currently with the CentOS Plus kernel, as XFS is already compiled as a module on that kernel. After some testing here (if all goes well), a new CentOS Plus kernel w/out XFS will be compiled and this code will also be moved (with instructions) to the CentOSPLus repo. ------------------------------------------------------- NOTE: After completing the install of the XFS code, you should edit /etc/yum.repos.d/CentOS-Testing.repo and set the line: enabled=1 TO enabled=0 to turn off the testing repository for CentOS-4 until you want to upgrade items from it again. This repo will get other Alpha/Pre Release type code in it and you would not want to accidentally overwrite stable CentOS packages during updates. --------------------------------------------------- Thanks, Johnny Hughes CentOS-4 Lead Developer

RHEL4 2.6.9-22EL xfs module src.rpm for testing
by Eric Sandeen 18 Nov '05

18 Nov '05

Hey, let's give it a whirl. No promises, but please do let me know how it works out. I've also sent this out to the linux-xfs list. ftp://oss.sgi.com/projects/xfs/testing/RHEL4/ ################################################################# # # # NOTICE # # This xfs module rpm has been provided for testing purposes # # only. It is believed to be functional, but it has not been # # heavily tested. In particular, you may have issues with the # # 4KSTACKS option on RHEL4 ia32 kernels, depending on your IO # # hardware, layering, nfs usage, etc. # # # # Please do NOT report any problems with this module, or with # # the kernel when this module is loaded, to Red Hat. # # You may report issues to the linux-xfs(a)oss.sgi.com list. # # (Please also report successes!) # # # ################################################################# To rebuild, do something like this: rpmbuild --rebuild --target i686 --define "kernel_topdir /lib/modules/2.6.9-22.EL/build" kernel-module-xfs-2.6.9-22.EL-0.1-1.src.rpm where the --target should match your architecture (actually not needed for x86_64 or ia64, it just affects the rpm name), and the kernel_topdir is /lib/modules/`uname -r`/build for the RHEL4 kernel you wish to build against. I have tested this xfs codebase a little bit with the xfs qa tests from xfs-cmds cvs with the 2.6.9-22.ELsmp kernel on ia32. It should work on other architectures and flavors (bigmem, non-smp, etc), and it may work with other RHEL4 kernel versions, but no guarantees on that. -Eric

A patched kdepim package(for CentOS 4.2) for CJK user
by dlion 01 Nov '05

01 Nov '05

Hi, all I have build a patched kdepim package for CJK user. More specifically, Knode is patched to support locale-dependent groupname encoding. CJK means Chinese, Japanese and Korean. They all need multi-byte charset(MBCS). A RFC requires that all newsgroup groupnames are encoded in UTF-8. Most newsreaders under UNIX are designed this way. But due to Microsoft products' feature(or call it bug), locale-dependent groupname encoding is the de facto standard in some CJK area. This package changes knode's behavior from UTF-8 to locale-dependent encoding, and will be helpful to CJK users. Non-CJK users probably will not need this package. And this package replaces the official kdepim package. Therefore, I think this package should go to centosplus directory. The knode patch is not written by me. I only build this kdepim package. It is from a chinese Linux distribution called Magic Linux. You can get the original patch from http://www.magiclinux.org/dev/old-1.2/cd1/SRPMS/kdepim-3.3.2-1mgc.src.rpm The original package is GPLed. So this patch is available under GPL. I, and some other users, have tested this patch, and it works. I hope this package can be merged into the CentOS repository(centosplus directory). And, I do not have a stable and secure space to store this package, I request a space(for example, a ftp account or a web space) at least 15M bytes large, so I can upload the SRPM.
