I am running a 2.6.26 kernel on debian lenny having a 6 TB data
partition under xfs, 2.6 TB are in use now.
xfs fs is exported via nfs from that box.
after 12 weeks of popper service suddenly nfs performance was a disaster
and the box was stuttering, system load was about 10.
There was no indication for a hardware problem. HW Raid status was *OK*
/var/log/messages lists several thousand lines like:
Aug 6 21:12:03 nfsserver kernel: [7660448.840139] Filesystem "sdb1":
corrupt dinode 4806258, (btree extents). Unmount and run xfs_repair.
(allways the same dinode #)
after stopping nfsd and unmounting the fs
both xfs_check and xfs_repaier did not detect any corruption!
back in service i got the same problem and log lines.
So what is wrong here?
There might be a fs issue and the fs utilitys are not able to detect it ?
I did a metadata dump of that fs and could post it, would this help to
determine what is going wrong here?
