Hello Dan,
No this is not a bug, but rather a missunderstanding of the user. As is
documented in the manual, the MediaType directive is a key element in a
Bacula Storage daemon. Bacula by design assumes that if the director
requests a volume with media type X, that that volume can be loaded on any
device that accepts media type X. If you have two "incompatible" devices
(e.g. two autoloaders, or a fixed drive and an autoloader) where you don't
want to manually move volumes from one autoloader to another or the fixed
drive, then you must use different media type.
Best regards,
Kern
