Hi Michael,
You might try setting the enabled field to '0' for all volumes which are - or
should be - inaccessible (not in library), and therefore should not be
considered by Bacula as viable.
I had to implement this on my system a couple years back, and it has been
working fine ever since: http://revpol.com/node/146
I wrote that script to work out this same problem I was having when vchanger
drives were not in the drive caddy, and hence the file volumes on them were
not available.
You will surely have to adapt it, or probably just pick a few things from it
for your specific system because it is highly vchanger v0.8.6 centric. :)
Having said that, it is typically best to let Bacula manage what volumes it
wants, when it wants them, but in my situation, each hard drive I use with
vchanger has about 70 10GB volumes so I am not severely limiting Bacula, just
guiding it a little and giving it a nudge. e.g.: I do not touch retention
times, nor do I manually force purges etc. :)

I have used the various job "max ... time settings" for things like this in
the past.
