Once you get it unmounted (check that other processes are not using it,
you may need to switch to init level 2 or even 1...
Anyway, once it is unmounted, you should use:
xfs_check /dev/md5
and then try
xfs_repair /dev/md5
If you need to reboot to umount the volume, you may need to mount it
once and then umount it to make sure that the journal (log) is replayed
before doing the xfs_repair.
You can see some scripts I have that do this "automatically" for my
servers using rebooting into LILO to even handle the "/" mount at
