Hi Josh,
I have upgraded to bacula 2.2.5 and I'm still having the same problems.
It seems like drive-1 in the vchanger is never used. Have you ever seen it
used, and if so, what kind of configuration do I need; I followed the
instruction in the HowTo document (Rev 0.7.4 2006-12-12). I tried many
configurations but I still can't get it to run more than one job. If I start
a second job it will fail.
What I'm trying to accomplish is the following: I created an LVM disk using
2x500GB disks. I created a vchanger with 2 virtual disks to backup to the
LVM. Originally I created the vchangers with multiple 500GB disks, but I
changed to use the LVM; that setup didn't work either. Even with one
vchanger per 500GB disk, I still couldn't start more than one job at a time.
I can the relevant parts of my conf files if that helps.
I would like to run concurrent jobs to backup to different volumes on the
LVM disk. Bacula doesn't seem to be able to do that. Every time I start more
than one job, each one after the first fails.
Here is a sample console output illustrating this problem:

I don't believe bacula's volume reservation worked well with multiple
drive autochangers before version 2.2.0. If you are using a pre-2.2.0
release, then that is likely why bacula is not selecting another drive
on the autochanger, even though it is loaded with a usable volume. For a
single vchanger to be able to run multiple concurrent jobs (one on each
virtual drive), you need bacula 2.2.0 or greater.
