Hi Thibault,
From what I recall of my bacula install, it is better to set the
Changer Device to a linked device that is updated on boot, as /dev/sg3
might be the autochanger but in a reboot could become a drive and the
autochanger move to /dev/sg2 (for example). I use the following script
run after reboot to set the autochager properly:
#! /bin/bash
# Find the autochanger device and create the /dev/changer link
for i in /dev/sg{0..4}# the range might be different for you!
do
if (tapeinfo -f $i|grep "Medium Changer"); then
logger -t rclocal "Will create changer link to $i"
if readlink /dev/changer; then
unlink /dev/changer
logger -t rclocal "Removed an existing /dev/changer link"
fi
ln -s $i /dev/changer
fi
done
Regards,
Iñaki

Hello Bacula Users community,
I need advices/best practicies about configuration of an Autochanger
I've read the documentation on bacula website, and it works like a charm,
except one point
First of all,
- bacula-dir / bacula-sd / bacula-fd version 7.4.4 / SQLite -- running on a
Debian 9 virtualized server
- Autochanger is a DELL PowerVault TL1000 with an LTO 6 drive -- Firmware up to
date
- tapes have a code39 barcode
- server / autochanger is on a remote location, I don't have physical access to
it
----
Storage {
Name = Changer_TL1000
Password = "hellothere"
Address = servername
SDPort = 9103
Device = TL1000
Media Type = LTO-6
Heartbeat Interval = 60
Autochanger = yes
Maximum Concurrent Jobs = 20
}
Autochanger {
Name = Changer_TL1000
Device = TL1000
Changer Command = "/etc/bacula/scripts/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg3
}
Device {
Name = TL1000
Archive Device = /dev/nst0
Media Type = LTO-6
LabelMedia = yes
Random Access = yes
AutomaticMount = yes
RemovableMedia = Yes
AlwaysOpen = yes
AutoChanger = yes
Check Labels = yes
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
Spool Directory = /opt/bacula/spool
Maximum Spool Size = 50GB
Maximum Network Buffer Size = 65536
Maximum job Spool Size = 15GB
}
The problem occurs when I want to label a tape. It does not seems to label the tape, but
instead the "drive".
There's something I must have misunderstood in the config.
For example, the drive was loaded with tape called VGOBQ001.
I've asked my local contact to set a new tape into the drive, and label it with the
bconsole "label" command, what he did (label : VGOBM002)
When I "list volume" on bconsole, I can see the volume VGOBM002 has been
successfully created.
He left VGOBM002 tape in the drive. Today's backup starts, and needs VGOBQ001.
Bacula unloads the drive, and loads the correct tape.
Here's the log
JobId 23: 3307 Issuing autochanger "unload slot 1, drive 0" command for vol
VGOBQ001.
JobId 23: 3304 Issuing autochanger "load slot 3, drive 0" command for vol
VGOBQ001.
JobId 23: 3305 Autochanger "load slot 3, drive 0", status is OK for vol
VGOBQ001.
JobId 23: Error: The Volume= on device=VGOBM002 appears to be unlabeled. #What
the hell ?
JobId 23: Volume "VGOBQ001" previously written, moving to end of data.
JobId 23: Ready to append to end of Volume "VGOBQ001" at file=3160.
Then the job starts with the correct VGOBQ001 tape.
The problem is the Error line, how can my volume has no label, but my device
has one ?
Did i miss something in the config ?
Thank you for your support,
Thibault
