Hello Kern,
Thanks for your answer.
But I don’t think what’s you’re pointing is related to my case as I‘ve only one
autochanger.
To give more detail on my configuration:
· I make a daily incremental backup on different servers (Pool Default)
· Every weekend I make a full backup of the servers (Pool_Full_Week)
· I make a monthly full backup of servers (Pool_Full_Month)
Here are my pools definitions in bacula-dir.conf:
# Default pool definition
Pool {
Name = Default
Pool Type = Backup
Recycle = yes # Bacula can automatically recycle Volumes
AutoPrune = yes # Prune expired volumes
Volume Retention = 30 days # one month
Cleaning Prefix = "CLN"
RecyclePool = Scratch
}
# Full pool Month definition
Pool {
Name = Pool_Full_Month
Pool Type = Backup
Recycle = yes # Bacula can automatically recycle Volumes
AutoPrune = yes # Prune expired volumes
Volume Retention = 7 years # one year
Cleaning Prefix = "CLN"
RecyclePool = Scratch
}
# Full pool Week definition
Pool {
Name = Pool_Full_Week
Pool Type = Backup
Recycle = yes # Bacula can automatically recycle Volumes
AutoPrune = yes # Prune expired volumes
Volume Retention = 1 years # one year
Cleaning Prefix = "CLN"
RecyclePool = Scratch
}
# Scratch pool definition
Pool {
Name = Scratch
Pool Type = Backup
Cleaning Prefix = "CLN"
}
Here is my Storage definition in bacula-dir.conf:
Storage {
Name = Autochanger
Address = 192.168.27.7 # name or IP address of the server that hosts the daemon
storage
SDPort = 9103
Password = ""
Device = "Autochanger" # the same as defined in bacula-sd.conf
Media Type = LTO-5
}
Here is my bacula-sd.conf:
Autochanger {
Name = Autochanger
Device = Drive-1
Changer Command = "/etc/bacula/scripts/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg2
}
Device {
Name = Drive-1 #
Drive Index = 0
Media Type = LTO-5
Archive Device = /dev/nst0
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
Autochanger = yes;
LabelMedia = no;
}
I don’t get why bacula tries to use tape that are not in the autochanger,
beside the fact that there are a lot of usable tapes in it that are in the
Scratch pool…
Thanks for your help,
Gael Guilmin

Hello,
Probably 95% of all such problems are due to configurations where the MediaType
is not properly set.
- If you are using any form of autochanger, each autochanger must have a
*unique* MediaType.
- Each Device configuration in the SD must have a unique MediaType for each
different ArchiveDevice definition. Said the other way around, each
ArchiveDevice definition must have its own unique MediaType.
The .conf files you list are incomplete, so it is not possible to analyze them,
but when I see: MediaType = File, that raises a red flag that indicates that
there may be other Storage devices with the same MediaType, and if that is the
case, sooner or later, you will find that Bacula is very confused.
In the next Bacula version, I will probably modify the SD and possibly the Dir
to require unique MediaTypes, then this problem will be resolved.
I don't usually supply "support" because I don't have the time, but this
particular problem interests me from the standpoint that I would like to
prevent it, but with no console/job output showing the failures and incomplete
DIR and SD confs I cannot do any more.
Best regards,
Kern

I’m also running into this issue.
In my case, I’ve setup a disk-based auto-changer (vchanger) with two pools:
Full and Weekly. Each pool has multiple drives with 8 volumes on each drive.
The script that mounts the disk also issues an “update slots” command in
bconsole, and I can verify that bacula sees the correct volumes as “InChanger”.
When I swap out disks (weekly), Bacula continues to look for volumes that were
append-able, but on the previous disk (and not currently marked as “InChanger”)
and refuses to write to the append-able volumes on the new disk that are marked
as “InChanger”. It marks all the previous volumes it cannot access as “Error”,
and only then will it begin writing to the currently loaded volumes.
This line from the “Recycling Algorithm” led me to believe that it would use a
volume that was InChanger first: "If the request is for an Autochanger device,
look only for Volumes in the Autochanger (i.e. with InChanger set and that have
the correct Storage device).”
But it seems I’m missing something. I’ve included relevant bits from my
bacula-dir.conf file if anyone can see what I’m doing wrong. I’m getting this
on two systems, one running Bacula 5.2.12 and one running 7.0.4.
My other option is to split these all into separate pools, but that’s going to
make scheduling much harder.
Thanks in advance!

Hello,
I'm facing an issue with Bacula (5.2.12) on a Ubuntu server (12.04.4 LTS): I
don't know why, but the server, after finishing writing on a tape, tries to use
a tape that is not in the autochanger, despite the fact that there are plenty
of online and usable tape in the Scratch pool...
Any idea?
Best regards,
Gael
