I've implemented a solution posed in this thread, details of which were
clarified by Mike. I've now tested it and it seems to work as advertised.
I'm largely satisfied with the results. So I'll briefly describe in this
final post on the topic the steps I followed to implement the solution.
I used (slightly dated) information found at
http://ubuntuforums.org/showthread.php?s=f0b20f9e8542e9996088a02a2beb03be&t=168221
to get data that would allow me to create a udev rule for each of the
drives I'm using. This was necessary, in my case, for a few reasons: 1) I
will not have more than 1 drive plugged into the system at one time; 2)
the distro I use, Mythbuntu, is set to auto-mount attached USB storage;
and 3) the mount points for these drives need to be consistent and unique
for this solution to work on my system. 1) and 2) can lead to the
possibility of two of my drives sharing a mount point which, while not a
show-stopping outcome, could lead to some confusion at the least. Caveat:
this solution may not be applicable to other scenarios, e.g., those in
which a single USB drive is used or in the case of distros that are not
configured to auto-mount attached USB drives.
So, using information gotten from the supplied link I got data that
allowed me to create a udev rule for each of my drives. Then, I created
unique mount points and corresponding fstab entries for each drive based
on the udev rules I created. Incidentally, I put these mount points under
the disused (at least by Ubuntu and variants) /mnt directory, so as not to
confuse these with auto-mount entries the system is configured to place
under the /media directory. Next, I created a single folder on each
mounted drive. Then, I added that folder, along with the rest of the path
to it, as a storage group under Mythtv setup. Finally, I moved a recording
to one such folder on a newly-mounted drive as a test--success! I was able
to view the recording so long as the drive was connected. When the drive
is not connected and I try to view the recording the system simply tells
me it can't find the recording.
Now, each time I plug one of my drives into the system it gets mounted at
the specified mount point. I can view recordings stored on each drive or
move over to them more recordings for long-term storage. Overall I'm happy
with the result. The only minor inconvenience is the need to unmount the
drives when I'm finished viewing/archiving, so as to be able to power off
the drive.
Thanks,
James
