Hello,

Just recently upgraded to 2.6.0-test5-mm3 and am experiencing some
corruption issues on an XFS filesystem. I've been tracking the mm series
through the 2.6.0-test kernels and this is the first I've seen.

I use rsync to backup a volume on a software raid device to another raid
set created from device mapper. The target is a 2 drive setup connected
to a PDC20276 which is defined as a raid0 in the Promise BIOS. There's
no ata-raid in 2.6 yet, so I use dm which works fine.

An rsync from the software raid to the Promise set results in FS
corruption on an XFS filesystem. The rsync will usually complete, but I
am unable to use the filesystem afterward. I have a backup fstab that
needs to be copied and it results in "Operation not permitted", strace'd
output attached.

If I umount the filesystem and run xfs_repair on it, it will proceed
till the end where it rebuilds directory inode 256 - this is the only
item needing repair. This happens every time. I can then mount it and
copy my file with no problem. This corruption is consistent and so far
has happened each time I use rsync to backup since going to -mm3. I've
tried patching in a CVS pull of the xfs filesystem from 9/20/2003 and
have the same results.

Any ideas? Let me know if you need more information or would like me to
try something. Thanks,

-Walt
