I have a filesystem which I cannot repair with xfs_repair. Running
xfs_repair results in its finding and fixing the same errors, over and
over and over. Whenever I attempt to manipulate certain directories,
the filesystem shuts itself down:

I think the second and third "xfs_force_shutdown" calls came after I
unmounted, remounted, and attempted to repeat the "rm" that had failed
with the first one, without an xfs_repair attempt in the interregnum.
I tried copying it from one filesystem to a new one, using tar. It
worked fine for a while, but then I had an "unplanned" shutdown due to a
failure in the RAID devices. Since then, the same problems have arisen.
Is this a normal problem? Should I just give up and copy to a new
filesystem?
