Hi
We've been struggling with this problem for a few weeks and i'm completely out
of ideas on how to permanently solve it, so any help will be appreciated.
We have a 'Weekly' pool which comprises 5 different LTO-3 tapes: W001, W002,
... W005. One tape per whole week. This pool is configured this way:
Pool {
Name = Weekly
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Use Duration = 4 days
Volume Retention = 15 days
Recycle Oldest Volume = yes
Purge Oldest Volume = yes
Maximum Volumes = 5
}
And backup jobs follow this schedule:
Schedule {
Name = "MonthlyCycle"
Run = Level=Full Pool=Weekly 1st thu at 23:05
Run = Level=Full Pool=Weekly 2nd-5th mon at 23:05
Run = Level=Incremental Pool=Weekly 2nd-5th thu at 23:05
}
The problem is that bacula always recycle the wrong tape on Mondays. For
example, if it is supposed to use tape 'W005' this week, it will recycle and
ask for 'W001', next week's tape. Backup jobs fail and this error comes up:
23-Oct 23:05 br01 JobId 666: Start Backup JobId 666,
Job=Backup-br01.2010-10-25_23.05.00_36
23-Oct 23:05 br01 JobId 666: Using Device "LTO-3"
23-Oct 23:05 br01 JobId 666: Warning: Director wanted Volume "W001".
Current Volume "W005" not acceptable because:
1998 Volume "W005" status is Used, but should be Append, Purged or Recycle.
23-Oct 23:05 br01 JobId 666: Please mount Volume "W001" or label a new one for:
Job: Backup-br01.2010-09-20_23.05.00_36
Storage: "LTO-3" (/dev/nst0)
Pool: Semanal
Media type: LTO-3
Funny thing is that W005 is in fact the oldest volume and first on the queue to
be recycled.

So every Monday I must open bconsole and manually change back the volume status
of the next tape (in this case W001) to 'Used', so that the current tape is
correctly recycled. But I think this action could be actually provoking the
situation, but I'm not sure. I'm thinking about maybe changing 'Volume
Retention' to a longer time, 28 days for example.
Any ideas?
