Well, they are initially created on drive-0, but it does not matter which drive the volumes in the "slots" are created on. Once created, a volume from any slot can be loaded into any available drive. The Bacula Storage Daemon decides which drive of a multi-drive changer to load a slot's volume into. It appears that Bacula does not do any kind of "load balancing", (for lack of a better term), but simply chooses the lowest available drive index. In other words, drive-1 will only be used if drive-0 already has a volume loaded and that volume is opened for reading or writing. For example, let's say drive-1 is empty and drive-0 has the volume from slot-4 loaded, but that volume is not currently being used by any active job. If you run a job and Bacula determines that it needs the volume from slot-2, then it will not load slot-2 into the empty drive-1. Instead it will unload the volume in drive-0 back into slot-4, then load the needed volume in slot-2 into drive-0. Bottom line: You must run two jobs concurrently to make use of drive-1. For the disk-based virtual changer, the only reason to have more than one virtual drive is if you want to run multiple jobs concurrently. > ------------------------------------------------------------------------- Take Surveys.
