After repairing the volume, I was still unable to mount the volume. Turns out the journal was corrupt. Again, I don’t get how this can happen. I was able to issue the following command:
% /System/Library/Filesystems/hfs.fs/hfs.util -N /dev/disk1s2
Turned off the journaling bit for /dev/disk1s2
I then re-ran the fsck option and then remount the volume. It complained again that the volume was corrupt, but this time let me mount the volume. I am now syncing the data over to a new set of drives so that I can re-purpose these drives.
