Bug 2934
by admin 11 Oct '08

11 Oct '08

I'm attempting to build a PHP 5.2.5 package for CentOS 5.2 (x86_64) using a Fedora SRPM. Satisified all dependencies and looked like it was going to build, but barfed at the end with a known apr/apxs issue - CentOS bug 2934. A workaround suggested in bug report didn't work, but produced a related but different error (I've updated the bug report). There is supposed to be a yum package in testing that fixes this issue. Where can I access the testing repo, or this package? Thanks Mick

CentOS Release Timeline (Graphical Display)
by Alain Reguera Delgado 09 Oct '08

09 Oct '08

Hi Guys, Following Dag's idea (May I Dag ?) of create a CentOS timeline graphical table ... here is a variation of it made last month. Maybe it could be used on http://wiki.centos.org/FAQ/General#head-fe8a0be91ee3e7dea812e8694491e1dde5b… as ilustration. It is a svg file with markers that could be included into our Artwork Building Environment to have it on different languages. Actually the "You are here" pointer is modified manually. Some way to automate this would be cool (IMO). See: http://wiki.centos.org/AlainRegueraDelgado?action=AttachFile&do=get&target=… http://wiki.centos.org/AlainRegueraDelgado?action=AttachFile&do=get&target=… What do you think ? Cheers, al.

Re: xfs volume can not be mounted with uuid or label, only scsi device name /dev/sdb (solved)
by John Shen 08 Oct '08

08 Oct '08

james, thank you so much for your help. indeed, the problem is that /etc/blkid/blkid.tab still has the old ext3 entry. i changed TYPE to xfs and updated the uuid for /dev/sdb, and now it mounts fine with UUID. since i prefer UUID anyway, i did not test label, but assume it was the same issue. yes, we do use the entire device, which never had problems with other fs types, which mount seem to update blkid.tab automatically. still not sure why it did not do so for xfs, but as long as it works, i am happy. cn=John Shen,title=Sys.

Works fine for me: # xfs_admin -lu /dev/sdb label = "/test" UUID = 9aa81fbd-3f6d-4d3d-a40f-2a5483f8fe5c # mount LABEL=/test /mnt/tmp # df /mnt/tmp Filesystem 1K-blocks Used Available Use% Mounted on /dev/sdb 11584 64 11520 1% /mnt/tmp # mount | grep /mnt/tmp /dev/sdb on /mnt/tmp type xfs (rw) # umount /mnt/tmp # mount UUID=9aa81fbd-3f6d-4d3d-a40f-2a5483f8fe5c /mnt/tmp # df /mnt/tmp Filesystem 1K-blocks Used Available Use% Mounted on /dev/sdb 11584 64 11520 1% /mnt/tmp # mount | grep /mnt/tmp /dev/sdb on /mnt/tmp type xfs (rw) i.e. the above is an XFS file system on the whole of /dev/sdb - which I can mount fine via its LABEL or UUID ... However, it appears that this only works if there is an entry for this file system in /etc/blkid/blkid.tab (that mount creates/updates) If I umount the file system, and then remove the line for /dev/sdb in /etc/blkid/blkid.tab - I then can't mount by LABEL or UUID - unless I previously mount by device ... This appears to be the case for ext3 as well as xfs ... Using a partition, then all works as expected.

That was how I got the LABEL and UUID: [root ~]# /usr/sbin/xfs_admin -lu /dev/sdb label = "/mysql2" UUID = 2560a02a-239b-4ac5-affe-cf71f8e87150 cn=John Shen,title=Sys.

HPC Channel in CentOS
by Tsai Li Ming 06 Oct '08

06 Oct '08

Hi Will CentOS be considering to roll out their own hpc channel, since Red Hat has announced it[1]? The SRPMS will be out soon. Since Platform OCS is 100% based on Project Kusu[2], I will be able to assist to help CentOS to have their own hpc channel. Due to the specialized nature of HPC, my team will be ready to help out in the CentOS forums or mailing lists. -Liming Team Lead Project Kusu [1]http://www.redhat.com/about/news/prarchive/2008/Linux_HPC_Platform.html [2]http://www.hpccommunity.org/index.php?pageid=Kusu

sorry for the confusion, i did use the uppercase in fstab. # neither of the following works # UUID=2560a02a-239b-4ac5-affe-cf71f8e87150 /var/lib/mysql xfs noatime 0 0 #LABEL=/mysql2 /var/lib/mysql xfs noatime 0 0 # only this works /dev/sdb /var/lib/mysql xfs noatime 0 0 cn=John Shen,title=Sys.

I think you need to use uppercase for LABEL= and UUID= James Pearson

Is there an ETA on an updated kmod-xfs for the latest kernel? Looks like the package is still for the .10.el5 kernel. Thanks! J.

update w.r.t VM's for forums / portals testing
by Karanbir Singh 05 Oct '08

05 Oct '08

hi Guys, We were hoping to use a series of VM's hosted at flexiscale.com for doing this testing. However, it was just sheer bad luck for us that they decided to do some maintenance work starting the 26th Sept, which are still ongoing. But I am hopeful that they will be done by Monday the 6th. Fallout for us is that while this maint work is going at their end, we cant create any new VM's. This was totally not planned from our side, even the initial announcement that came through only said work would start on the 26th and be done in time for business hours 29th Sept. But it seems that they were unable to finish the work, and its still ongoing. If there is still no progress with the issue on Monday, we can setup a Xen instance and go via that route, at a different setup. -- Karanbir Singh : http://www.karan.org/ : 2522219@icq
