This does seem to imply that md0 exists on the combination of hdc6 and
hda6. So if it is formatted, you should be able to mount it. Have you
tried to mount /dev/md0? Possibly it won't be ext2, so try anything else
that might be the type...reiserfs, xfs, ext3. If none of those, then you
should be able to format it and mount it. Similar for md1 through md3,
all apparently set up as raid1. Beware there have been some
incompatibilities that are being worked on for raid1 and several of the
non-ext2 filesystems.
