Hi Brian,
I am using 2.4.2 on CentOS 5.2
I found out that issuing "update slots" can solve the issue.
It looks like even if bacula itself chose the right volume, loaded it
from the right slot into the right drive, it sometimes seems to forget
what it just loaded. When that happens, I do "update slots" and after
some seconds bacula starts writing to the already loaded tape.
Sometimes it takes an unload, reload, update slots to fix things.
But this is just my impression. It would take more detailed
investigation to tell what "really" happened. I turned debugging on so
maybe next time I'll be able to narrow down the issue.
I really don't think that this is a general problem because in this
case the mailing list would be flooded with bugreports. Maybe its some
kind of rare communication problem between bacula and mtx / mt or
something similar.
Regards, Nils

Maybe a stupid question, but did you try issuing a mount command on the
right drive?
