Just wanted to chime in with a "me too". Our main filserver runs over a
6 disk software raid5 on U160 drives and I've had a few corruptions
causing it to go down. The filesystems were created around Nov. 2002 and
I was bitten by the "clean umount may corrupt root FS" bug around that
time. Two or three times since, I've had to xfs_repair the filesystem
which has resulted in moving the contents of the FS to lost+found/128/.
It's an AMD SMP box utilizing the 760MPX chipset. After an xfs_repair,
mount, umount and subsequent check, the filesystem appears clean. I've
thought about re-mkfs'ing the filesystems in case there is some left
over cruft that might be causing it. I'm open to ideas.
