Sure... also to the list, as I guess it might be interesting to
others, too...
This is one of several disk-based virtual autochangers:
backup@gnom:~> cat /baculadata1/filestorage01/disk-changer.conf
maxslot=700
maxdrive=4
From the SD conf:
Autochanger {
Name = File01
Device = File01a
Device = File01b
Device = File01c
Device = File01d
Device = File01e
Changer Command = "/opt/bacula/etc/disk-changer %c %o %S %a %d"
Changer Device = /baculadata1/filestorage01/disk-changer.conf
}
Device {
Name = File01a # a to e
Media Type = File01
Device Type = File
Random Access = Yes
Archive Device = /baculadata1/filestorage01/drive0 # 0 to 4
Drive Index = 0 # 0 to 4
Label Media = Yes
Autoselect = Yes # No for File01e / Drive 4
Maximum Spool Size = 10G # spool sizes as needed.
Maximum Job Spool Size = 10G # Sounds nonsense for disk,
# but I'm using slow external ones here...
Spool Directory = /baculaspool
Autochanger = Yes
}
From the DIR conf:
Storage {
Name = FileCh
Address = gnom
SDPort = 9103
Password = "sure"
Device = File01
Media Type = File01
Autochanger = Yes
Maximum Concurrent Jobs = 8
}
Pool {
Name = Whatever
Pool Type = Backup
Recycle = Yes
Auto Prune = Yes
Volume Retention = 3 months # as needed
Storage = FileCh
Maximum Volume Jobs = 1 # rather important IMO
Maximum Volume Bytes = 3G # no. of volumes * this size
# determined experimentally... 2.1 TB is *more* than the disks
# capacity, but on average, I've got one volume half full per job
Volume Use Duration = 6h
Catalog Files = Yes
Scratch Pool = DiskScr # This is a device-specific scratch pool
Recycle Pool = DiskScr
Next Pool = DLTLong # migration to tape
}
Status storage output snippets:
Autochanger "File01" with devices:
"File01a" (/baculadata1/filestorage01/drive0)
"File01b" (/baculadata1/filestorage01/drive1)
"File01c" (/baculadata1/filestorage01/drive2)
"File01d" (/baculadata1/filestorage01/drive3)
"File01e" (/baculadata1/filestorage01/drive4)
...
Device "File01a" (/baculadata1/filestorage01/drive0) is not open.
Slot 591 is loaded in drive 0.
Device "File01b" (/baculadata1/filestorage01/drive1) is not open.
Slot 523 is loaded in drive 1.
Device "File01c" (/baculadata1/filestorage01/drive2) is not open.
Slot 78 is loaded in drive 2.
Device "File01d" (/baculadata1/filestorage01/drive3) is not open.
Slot 474 is loaded in drive 3.
Device "File01e" (/baculadata1/filestorage01/drive4) is not open.
Drive 4 status unknown.
And I excluded disk volumes from query 15...
Does that help?
