XFS error cannot mount RAID

XFS error cannot mount RAID

I have a AMCC RAID 5 which has been verified without error but cannot mount on 
a SUSE 10.1 OS. Inconsistency on the volume may have occurred during an 
abrupt power shutdown. Not sure if it would be prudent to run XFS_Repair at 
this stage since XFS_check returned info indicating inconsistencies exist.

Please assist in any way you can, thanks.

Well I know from experience that xfs_repair may bite, unfortunately,
and that 3Ware RAID-5 really is touchy about power... BBU really is a
must.
Anyway, here is what to do :
1) if possible, use xfs_dump to backup the whole filesystem as is on
some other device, tape, disk, whatever you have available.
2) run xfs_repair -n /dev/sdXX >> /tmp/testfile and send "testfile" to
the list.

good luck!
