[Vchanger-users] bacula requesting nonexistent slots

[Steven A. F. <ste...@gm...>]

I've had a working setup for years, but suddenly I'm getting errors:

Fatal error: 3992 Bad autochanger "load Volume v1_0005_0197 Slot 412, Drive 0": ERR=Child exited with code 1.
Results=cannot load drive 0 from invalid slot 412

bacula indeed thinks the volume is in slot 412, according to the "list media" command:

  1,501 | v1_0005_0197 | Append    |       1 | 23,539,407,831 |        5 |    3,628,800 |       1 |  412 |         1 | File      |       1 |        0 | 2023-08-09 00:54:13 | 3,511,018 |

I tried doing "vchanger /etc/vchanger/v1.conf REFRESH" which I thought would update bacula's inventory of the slots, but that doesn't seem effective.

If I ask vchanger what it has, using "vchanger /etc/vchanger/v1.conf LIST", I get:

198:v1_0005_0197

so vchanger thinks the volume is in slot 198.

I was able to get bacula to correct its slots via "update slots", and things are working again, but I'd like to understand how the slots/volumes might have gotten out of sync.  Any thoughts on that would be appreciated.

Also, is the "update slots" command the right way to recover?
