missed your reply on this one.... I'd almost given up on this one.....
>Why do you need to do this?
I have an app which occassionally throws errors suggesting the fs is at fault.
But in most cases, I'm not sure whether it's the fs or the raid underneath thats
causing it.
So I usually run xfs_repair with the -n switch.
Did you have an oops or a filesystem shutdown? i.e. anything in
syslog of note?
not recently, but in the past had some unclean shutdowns and on one instance I
did a umount -l on the raid set when it refused to unmount gracefully.
But I had re-raided the server since.

Did you have an oops or a filesystem shutdown? i.e. anything in
syslog of note?
