Ok, so I tried it again, and the same issue (bacula want a tape which
is mounted, but it doesn't recognize)
I tracked the problem i turned on debug in mtx-changer, and see about
mt -f /dev/nst0 status was telling "mt: /dev/nst0: No medium found"
Then I tried mt -f with the others three devices (I have an
autochanger with /dev/nst{0,1,2,3} as tapes) and see only nst2 was
online.
I changed my config to /dev/nst2, and bacula is now working again.
But I'm confused now ! :( :(. Somebody can explain me this situation ?:
# mtx -f /dev/autochanger1 status | head -6
Storage Changer /dev/autochanger1:4 Drives, 60 Slots ( 2 Import/Export )
Data Transfer Element 0:Full (Storage Element 2 Loaded):VolumeTag =
ISOXAD02
Data Transfer Element 1:Empty
Data Transfer Element 2:Empty
Data Transfer Element 3:Empty
# lsscsi
[0:0:0:0] mediumx HP MSL6000 Series 0520 /dev/sch0
[0:0:0:1] tape HP Ultrium 3-SCSI G63W /dev/st2
[0:0:0:2] tape HP Ultrium 3-SCSI G63W /dev/st3
[0:0:0:3] storage HP NS E1200-320 593d -
[1:0:3:0] tape HP Ultrium 3-SCSI G63W /dev/st0
[1:0:4:0] tape HP Ultrium 3-SCSI G54W /dev/st1
I can guess that first Data Transfer element listed in mtx -f dev
status is the first tape found in lsscsi command output. Then Data
Transfert Element 1 will be /dev/st3 and go ...
Is this true ? Should i name my devices with some persistente name
like "/dev/tape1" ?
And more important, why are others (three) devices like "not medium found" ?
See next session (first I loaded 4 tapes):
# mtx -f /dev/autochanger1 status | head -10
Storage Changer /dev/autochanger1:4 Drives, 60 Slots ( 2 Import/Export )
Data Transfer Element 0:Full (Storage Element 2 Loaded):VolumeTag =

Data Transfer Element 1:Full (Storage Element 1 Loaded):VolumeTag =
ISOVBF04
Data Transfer Element 2:Full (Storage Element 3 Loaded):VolumeTag =
ISOVAF03
Data Transfer Element 3:Full (Storage Element 4 Loaded):VolumeTag =
ISOLAD01
# Bacula is using Data Transfer Element 0:

My question now is, should be possible using /dev/nst3 while nst2 is
being used ? They are both connected through a NSR to the MSL library.
Sorry for this large post
Where do you recommend read about this kind of issues ?
Thanks !
PD: I'll upgrade to lenny / bacula 2.4, but this is like the problem
is not with bacula directly
