Post Bacula tape loading problem 
Hello,

We are running Bacula 5.0.1 on a 64-bit Ubuntu 10.04 server connected to a Dell TL2000 tape library with two LTO-4 drives. Before our Bacula jobs run each we load the proper tapes (from running the list nextvol command) into a slot in the library’s magazine. Then we run the update status slots command to update the Bacula database with the current tape/slot information.

The problem we are experiencing is that when the job starts in the evening it usually does not load the tape from the slot. As a result we have to manually mount the tape and then the backup job runs normally. However, on some nights Bacula does load the tape from the slot but this is the exception and not the rule.

Can anyone give me some ideas on how to troubleshoot this problem and get Bacula to automatically load the tape from the slot without any manual intervention? Thanks.

Jack Cobb

Does Bacula issue any mtx-changer commands (to try to load the tape)?

Do they do anything or do they fail?

The log might show that.

Martin,

John Drescher e-mailed that the unmount command (which we had been using
after each job) causes the drive to enter into a blocked state such that
manual intervention is required afterward to load the drive again. John
suggested using the release command instead and I have found that doing so
does not block the drive and thus should solve our problem.

Jack
