SOLVED - Merge storage groups.

Feel free to ignore this, its more so search engines can find what I
never located.

So I had two hard drives in my mythbox backend used for storage groups.
The 500GB was fine, the 1TB was starting to show many smart errors,
kernel errors in dmesg, and frontends would wedge trying to access some
recordings.

So I bought a 2TB and fitted it, moved all the dodgy drive recordings I
could, and all is well, I had 2.5TB of space...
which was a bit of a waste, so I wanted to move all recordings from the
500GB over to the new drive, and retask the 500 for backuppc storage.

This was dead-simple, just a matter of waiting for the backend to not be
recording anything to that storage group, then move all the files across.
Seriously, I thought there would be a lot of database updates required,
but that was all it took.

Then in the mythtv-setup command I had to remove /myth3 and leave
/myth1 (names are historic from when I had 3x 30GB drives for storage)
and update nfs exports and sundry housekeeping.

Why are you nfs exporting? Myth doesn't need it.

Just because I can - I already use NFS to get the videos directory
mounted on frontends. You're right, its not necessary for myth.
