Re: [Bacula-users] bextract - How To Eject and Load Next Volume?

[Maria M. <parody@u.washington.edu>]

You've probably already tried this, but I have had a problem 
occasionally before of getting the device busy error when trying to use 
mt-st, and just stopping the bacula daemons has gotten rid of it.  Worth 
a shot, anyhow, if you haven't tried already.  Doesn't answer the rest 
of your question, though.
