I'd upgrade xfsprogs before doing anything else.

Bad inode cluster on disk. You need to run xfs_repair on the
filesystem.

I'd suggest running "xfs_repair -n" to see whether that's the only
error and whether it's likely to be able to repair without making a
mess. If you don't have backups, you might want to mount -o
ro,norecovery and take a backup before trying to repair properly.
If you're really paranoid, take a metadump of the filesystem,
restore themetadump to a file and see if repair can fix the image
file first.

Cheers,

Dave.
