| |
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,
