Following the hint on:
https://gitlab.bacula.org/bacula-community-edition/bacula-community/-/issues/2683
i (re)post here, seeking feedback.
Situation: bacula 9.4 (debian buster), using RDX cassette/disks for backup,
using the wonderful 'vchanger' virtual autochanger script.
Following the vchanger doc:
https://vchanger.sourceforge.io/
https://sourceforge.net/projects/vchanger/files/vchangerHowto.html/download
it is needed to create a virtual changer device for every 'media' in the
'media pool'; so my SD configuration is:
Autochanger {
Name = RDXAutochanger
Description = "RDX Virtual Autochanger on ODPVE2"
Device = RDXStorage0
Device = RDXStorage1
Device = RDXStorage2
Changer Command = "/usr/bin/vchanger %c %o %S %a %d"
Changer Device = "/etc/vchanger/ODPVE2RDX.conf"
}
Device {
Name = RDXStorage0
Description = "RDX 0 File Storage on ODPVE2"
Drive Index = 0
Device Type = File
Media Type = RDX
RemovableMedia = no
RandomAccess = yes
Maximum Concurrent Jobs = 1
Archive Device = "/var/spool/vchanger/ODPVE2RDX/0"
}
Device {
Name = RDXStorage1
Description = "RDX 1 File Storage on ODPVE2"
Drive Index = 1
Device Type = File
Media Type = RDX
RemovableMedia = no
RandomAccess = yes
Maximum Concurrent Jobs = 1
Archive Device = "/var/spool/vchanger/ODPVE2RDX/1"
}
Device {
Name = RDXStorage2
Description = "RDX 2 File Storage on ODPVE2"
Drive Index = 2
Device Type = File
Media Type = RDX
RemovableMedia = no
RandomAccess = yes
Maximum Concurrent Jobs = 1
Archive Device = "/var/spool/vchanger/ODPVE2RDX/2"
}
every 'media' in 'media pool' have some volumes in the pool, more or less
like inserting in an (real) autochanger a set of tapes.
So when i insert a cartdrige, i get:
root@odpve2:~# bconsole

note the 'inchanger' and 'slot' property.
In this way, alla works as expected BUT if ALL volumes in a 'media' are
unavailable (typically because of some incorrect cycling of 'media'; we
cannot kill every collegues that insert the wrong cartdrige, because will
run quickly out of collegues ;-) bacula try to mount 'available' volumes
even on non-mounted 'media', eg, for volumes without the inchanger=1 property.
Some logs:
07-Mar 23:00 lnfbacula-dir JobId 18015: There are no more Jobs associated with
Volume "ODPVE2RDX_0000_0006". Marking it purged.

so, bacula find a volume in pool that can purge, purge it, and try to mount
it even if it is not 'inchanger', cannot access it, and put the volume in
'Error' state.
I've solve this for now with a simple script that lookup for volumes that
are in Error state with expiresin=0, and (if the related 'media' is mounted)
i reenable purging it.
But is strange...
