Hi All, we've run into a problem with the xfs component in the centosplus kernel (2.6.9-34.106.unsupportedsmp) where synchronous writes sometimes fail with EAGAIN. It's causing headaches for DB2 installs and for our database research group. There is a fix reported at:

http://marc.theaimsgroup.com/?l=linux-xfs&m=110808122904352&w=2

...that's supposed to take care of things. If there is any way these patches could be included in a future centosplus kernel, we would greatly appreciate it. We are enjoying the performance lift from xfs on many systems, and hate to throw it away to get a database to work.

Also, are there plans to produce a centosplus kernel that corresponds to the newest RHEL errata kernel (2.6.9-34.0.1.EL)?

Cheers and thanks,

David,

There is a centosplus kernel that has that errata ... it is version: kernel-2.6.9-34.107.plus.c4

However ... if the only thing you need from the centosplus kernel is the xfs ... you should use the normal (non-centosplus) kernel and the kernel-xfs-module that matches it from here:

http://dev.centos.org/centos/4/testing/i386/RPMS/

or

http://dev.centos.org/centos/4/testing/x86_64/RPMS/

(That code is from SGI and has all the latest patches.)

Thanks, Johnny Hughes
