Hi Bill,
I did find that script and used it as my inspiration. There were a few
issues I had when running it however. Firstly, it doesn't recognise
UUIDs in the format /mnt/vchanger/<uuid> which causes issues.
The script I wrote was designed to be run via udev on a hot insert /
remove of drives. This allows the script to run as soon as a disk is
started. It also uses /dev/disk/by-uuid to match UUIDs found in the
vchanger config.
The other difference is that I set InChanger=(0|1) instead of disabling
the volume. In theory, this will cause bacula to send a "Need
intervention" email instead of failing (but I'm yet to try this).
