Hi Chris,

Only certain scripts need access or even need to know this drive exists.
I deliberately do not have it in my fstab.  I use this drive as you 
would a removable flash drive.

What I am up to is trying to see if there is any clue as to why
I drop to maintenance mode every so often with a message that
fsck can not lock the drive because it is in use.  Our intrepid
heroes at Red Hat are troubleshooting this for me:

https://bugzilla.redhat.com/show_bug.cgi?id=836696

"cat /proc/mounts" in maintenance mode does not even show the drive as
mounted (it is not suppose to be).  And "lsof" shows nothing accessing
the drive (it is not mounted).

I am just digging around looking for any clue that might help them.
I just used your suggestion on "tune2fs -l /dev/mapper/lin-bak"
and posted it to the bug.

Thank you for the help,
-T
