Greetings,

We are using CentOS 4.4 along with the RHEL 4 compatible kernel modules
(downloadable here:
http://mirror.centos.org/centos/4.4/centosplus/x86_64/RPMS/).

According to the CentOS mailing list, the person at SGI who had been
backporting the xfs code for RHEL4/CentOS4 has left the company.

Are there any plans to continue this work?  It seems like we are getting
bit by this bug: http://oss.sgi.com/bugzilla/show_bug.cgi?id=410 but it
doesn't look like the fix has been backported to the RHEL4 kernel
module.

Hot topic today; see my reply on the centos list and other recent
threads on this list :)  I am planning to update the rpm package to
include some bugfixes soon, but it may not help your problems.

I had been tracking the sles9 xfs codebase as a fairly stable,
bugfix-only xfs codebase for this era of kernels; at this point I don't
-think- the extent changes you mentioned are in the sles9 codebase...
sgi guys?


If you are referring to Mandy's incore extent changes,
I don't see them in sles9 or sles10.

Having a quick look she has about 5 Mods.

Quite a bit of changes there for xfs_bmap.c and xfs_inode.c.
