Dear support group,

Sorry for bothering you, with what I think is a simple question, but I can't figure out what is going wrong.

At this moment I have version 11 of Bacula and the Bacula Administation Tool running on a Fedora 35 Server. As backup drive I am using a Quantum Superloader 3 with an internal HP LTO-4 drive connected to the onboard SCSI port.

So far I've got almost everything configured and up and running.
Up to the part the Superloader has to start working. Every time it quits with the famous "bacula-sd JobId 548: 3991 Bad autochanger "loaded? drive 0" command: ERR=Child exited with code 1. Results=cannot open SCSI device '/dev/sg7' - Permission denied". So I've read the manual and started Googling around, but I couldn't find anything that solves my problem.


The superloader is known in the system as /dev/sch0 and also as /dev/sg7.

Both are owned by bacula and in the group bacula and have read write and execute permissions.

The mtx-changer and mtx-changer.config have the same permissions

The drive has the same permissions, but when I remove the autochanger part in the config, it runs flawless.

So, I returned the autochanger in the config, and run the autochanger test from btape. No problems, everything works fine, so I concluded, there is nothing wrong with the config file.

When I execute load/unload and slots commands as root in a terminal window, the loader performs the asked operations. But when I ask for a slot update from bconsole as well as BAT, the message returned is "3306 Issuing autochanger "slots" command.

Device "Superloader3" has 0 slots."

It doesn't matter if I do this as normal user or as root, still the same error.

I even tried to run the storage deamon as root, but that doesn't work either.


I think I am missing something very small, but I can't figure out what I am missing.

Can you help me out?

Best regards,

Ronald de Haan
