Very slow on I/O?
by David King 22 Aug '06

22 Aug '06

I seem to be having a problem with CentOS releases 4.2 and 4.3. On a fresh install (on two very different pieces of hardware, one Dell PowerEdge server and one Compaq Presario), the system seems to be extremely slow. It happens primarily during any hard disk I/O. It's slow enough that my mouse skips slowly instead of moving smoothly, and I am unable to type. It seems to freeze for milliseconds at a time, which makes typing difficult because while it is frozen it seems to not accept keystrokes (that is, if I type the letter 'f' twelve times, only four of them may appear, depending on timing). It may be unrelated, but the clock seems to go more slowly during I/O as well (i.e. during times of I/O the clock runs behind more and more). If I were to extract a large tarball, I would have to wait for the while thing to finish before I could interact with the system at all A simple recompile of the kernel from kernel.org sources (which, as you can imagine, takes quite a long time) fixes the problem entirely, though. So is there something that differs wildly regarding the I/O scheduler between the stock CentOS kernel and the stock kernel from kernel.org? It would really be more convenient to be able to keep our kernel up- to-date automatically using the built-in packaging tools, so I hope that someone has seen the problem and has a work-around

The Readme file for the centos iso files says to get the docs for md5sum and CD burning from linusiso.org The linuxiso.org site has been down for many days. Is there an alternate site where these docs can be accessed? Charles L. Sliger, Information Systems Engineer, chaz(a)bctonline.com "No matter where you go, there you are..."

CentOSPlus kernel - Request for input
by Johnny Hughes 22 Aug '06

22 Aug '06

OK, I am building the new CentOSPlus kernel for i386/x86_64. It is based on the 2.6.9-42.EL kernel that will be part of CentOS-4.4. Currently it has all the features of the older plus kernels and all the items turned on by the upstream provider in their main kernel ... except that XFS is being removed from this kernel (and added by a standalone module that has newer sgi code for xfs). I am not going to add patches to the kernel, but I will entertain requests to turn on features that are included and require users to have to recompile their kernels (that don't require adding patches). If you currently have to change the config file and recompile the kernel, tell me the config items you are turning on and I will see if I can roll them into the new CentOSPlus kernel. I need all the input in the next few days ... so don't put it off :) Thanks, Johnny Hughes

syslogd/klogd problem on CentOS4.3
by Jeff Liu 22 Aug '06

22 Aug '06

Hi all, I have installed a CentOS4.3 box and migrated some application from FC1 to the new box, everything else runs perfectly except syslogd/klogd. /etc/rc.d/init.d/syslog starts without any problem, but there is nothing logged into /var/log/messages, even I restart the service. However, I tried to shut the service down and run "syslogd -m 0 &" and "klogd -x &" as root from shell, it works good. I have spent a lot of time, but still can not figure out why it does not work when starts by init as a daemon. Anybody had the same issue before? Any suggestion is highly appreciated. Thanks, Jeff L

[OT] RedHat's licence, CentOS rebuild
by Alain Reguera 22 Aug '06

22 Aug '06

Hello, I've been talking with some friends about the Redhat's SRPMs release issue. I've been reading the trademarks and some points of GPL. But get some confusion around the questions: Is redhat forced to release the sources of its product? Is redhat forced, due GPL licence, to make the sources of its product available to others (including those who don't buy the distro), and permit changes whenever the trademark guidelines were respected? There is some legal arguments that force the redhat's sources to be released. Is redhat's sources released by its kindness or because there is some legal document that enforced that. In a past post, I read that even if redhat close the distro, it has to release the sources to the client how buy the distro, so he/she would rebuild it and release a new one based on it as totally free. So, will CentOS have to buy the redhat distro to rebuild it and release it for free to the community in a close case ? Have we some guarantee that redhat will not close the srpms and the rebuilding will be safe ?. What does CentOS mean with: CentOS has no relationship with Red Hat(r), Inc. or RHEL. What happen with those countries that are not allowed to use redhat, can they use CentOS ? does redhat want this ? is this permitted by some legal argument. I'll really appreciate your comments about this, feel like I am in a neuronal crusade with this topic. my Regards to you and your Time Al.

using windbind to connect to AD
by James Marcinek 22 Aug '06

22 Aug '06

Hello, After a couple of years using Samba as a DC I figured I would start working it the other way around. I'm using CentOS, the latest and tried to use the GUI manager. I am sort of confused as there are acutally 2 windows. I filled out both and supplied the name of the AD administrator. Do I just put the AD domain in there with .realm after it? (eg testdomain.com.realm)? I tried with and without I then tried to login with an AD user, but used his username only (eg user1) but it didn't work. I am assuming that with this type of authentication, I will be able to login with user's from the AD directory... Has anyone worked with this setup before? Thanks, James
