If it's mirrored, or part of any RAID1 or higher configuration, you can
swap out the failed disk and rebuild the mirror.  If it is a single,
unmirrored disk ... sorry, but if it's failed, you're SOL.

Check the disk with smartmontools or similar before you assume it's bad,
and check your kernel logs for write failures.  Is it possible it's just
thrashing?
