Hallo bacula-users,
we are running bacula 5.2.3 on centos with an Adic Scalar 100 Autochanger. Two
times a week the tapes with volstatus full are changed with new and/or expired
tapes. New tapes are labeled via "label barcodes" and added to the scratch
pool, then "update slots" is run in bconsole.
Everytime a job starts and no appendable volumes are available in the
corresponding pool, bacula purges the oldest expired volume and requests it to
mount, although InChanger=0 is set. Our expectation would be that bacula uses a
volume from Scratch pool if no expired media is online within the corresponding
pool the job uses, but instead it requests the oldest expired volume,
regardless of its InChanger flag set to 0.
pool "CUS_MT_R-1":
+---------+------------+-----------+---------+-------------+----------+--------------+---------+------+-----------+-----------+---------------------+
| mediaid | volumename | volstatus | enabled | volbytes | volfiles |
volretention | recycle | slot | inchanger | mediatype | lastwritten |
+---------+------------+-----------+---------+-------------+----------+--------------+---------+------+-----------+-----------+---------------------+
| 236 | 003039L3 | Used | 1 | 757,822,464 | 1 |
1,800 | 1 | 4 | 0 | LTO-3 | 2012-01-19 15:05:16 |
+---------+------------+-----------+---------+-------------+----------+--------------+---------+------+-----------+-----------+---------------------+
the media 003039L3 is not online in the autochanger.
pool "Scratch":
+---------+------------+-----------+---------+-----------------+----------+--------------+---------+------+-----------+-----------+---------------------+
| mediaid | volumename | volstatus | enabled | volbytes | volfiles |
volretention | recycle | slot | inchanger | mediatype | lastwritten |
+---------+------------+-----------+---------+-----------------+----------+--------------+---------+------+-----------+-----------+---------------------+
| 99 | 003006L3 | Purged | 1 | 757,822,464 | 1 |
1,800 | 1 | 1 | 1 | LTO-3 | 2012-01-19 10:50:01 |
A expire and purge media is in the "Scratch" pool, but bacula is requesting the
offline media from pool "CUS_MT_R-1".
Here is the job message output from bacula.

If the pool "CUS_MT_R-1" is empty, bacula takes a online volume from Scratch
pool.
The question if the tape rotation handling is correct this way ?
Here the bacula configurations:
# test job - manual start
#
Job {
Name = "wntpsm2-System-Test"
Client = "wntpsm2"
Type = Backup
Level = Incremental
Storage = STOR_ADICSCALAR
Messages = Standard
Pool = CUS_MT_R-1
Priority = 10
Write Bootstrap = "/opt/bacula/working/%c_%n.bsr"
FileSet = "wntpsm2-Test"
SpoolData = yes
}
# tape pool
#
Pool {
Name = CUS_MT_R-1
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Use Volume Once = yes
Recycle Pool = Recycle
Volume Retention = 30 minutes
}
# bacula storage ressource
#

}
# bacula device ressource
#
Autochanger {

Media Type = LTO-3
Archive Device = /dev/tape/by-id/dummy
DriveIndex = 0

}
