Hi,
we had recently a hard disk failure in a Hardware Raid5 setup.
I thought this should give us no worries, but.... ( we had some more
disk failures over the last year in similar setups with no problems at
all).
Kernel is 2.4.20 CVS (SGI XFS snapshot 2.4.20-2003-01-14_00:43_UTC, with
quota and ACL's)
DELL PE 2550, 2 GB of RAM.
In the logs:

Please umount the filesystem, and rectify the problem(s)
The FS is about 1.6 TB, shared via NFS to about 50 Clients.
I tried to run xfs_repair -n, but without success:
hostxxx:~# xfs_repair -n /dev/sdb1
Phase 1 - find and verify superblock...
superblock read failed, offset 0, size 524288, ag 4294967295, rval 0
fatal error -- Input/output error
In the logs:

and so on (up to sector 255)
is there any chance to repair this?
thanks
Christian
