How are you ensuring that your devices retain persistent naming?
Please check the following once bacula and mtx changer list agree on tape
location:
While no jobs are running and using bconsole, mount one tape to each of your
tape drives until all of your drives are completely loaded. Verify that the
tapes in the drives are as expected in bconsole.
Example from my bconsole:
Used Volume status:
Reserved volume: 077099L5 on tape device "LTO5-6" (/dev/tape-admin6)
Reader=0 writers=0 reserves=1 volinuse=1
Reserved volume: 156751L5 on tape device "LTO5-3" (/dev/tape-admin3)
Reader=0 writers=1 reserves=0 volinuse=1
Reserved volume: 156759L5 on tape device "LTO5-2" (/dev/tape-admin2)
Reader=0 writers=1 reserves=0 volinuse=1
Using the OS mtx command status, do the tapes and drives match up with
bconsole's output?
Example from my mtx output:
# mtx -f /dev/changer-admin status
Storage Changer /dev/changer-admin:7 Drives, 320 Slots ( 10 Import/Export )
Data Transfer Element 0:Empty
Data Transfer Element 1:Empty
Data Transfer Element 2:Full (Storage Element 220 Loaded):VolumeTag = 156759L5
Data Transfer Element 3:Full (Storage Element 212 Loaded):VolumeTag = 156751L5
Data Transfer Element 4:Empty
Data Transfer Element 5:Empty
Data Transfer Element 6:Full (Storage Element 180 Loaded):VolumeTag = 077099L5
<clipped>
As you can see, my output aligns with on both sides. Please let us know what
your results are.

Subject: Re: [Bacula-users] bacula can't make use of multi drives
bumping this thread because I have another issue I am unable to resolve.
I am running:
bacula 7.0.5 compiled from source
3 pools.
Multiple jobs per pool.
10 tape drives
1 autochanger for those 10 drives.
1600 slots
running concurrent jobs works.
I have 41 volumes(tapes) in the virtual changer with 10 drives.
Bacula is getting confused very quickly on which volume is in which slot when
comparing whats in the bacula database,
as shown by select query, compared to the output of mtx-changer —list all
command. See below.
So as these volumes get more and more out of sync my jobs get hung with waiting
to mount volume which cascades to exceeding max jobs
as the running jobs start to queue. I’m wondering if this is a bug due to the
number of slots.
The fix is to release all 10 drives, run update slots. But I am having to do
this daily now. Unacceptable.
When I was setting this up I started with only 10 virtual tapes or volumes and
things ran smoothly.
Now I have added a 31 more tapes to prevent jobs from failing, if all the
tapes in a pool become full, and the problem has been exacerbated by
the increasing the number volumes.
It seems bacula is unable to handle this many slots and as it moves a volume
back to the slot from whence it came to pull another for a different job
and it puts the tape(volume) back into a different slot but gets confused and
Slot in the database is now wrong for this particular volume.
Does anyone have any experience with this? And is there a possible
configuration fix?
My max concurrent jobs is 20 for SD and max concurrent jobs per tapedrive is
1. This to keep jobs from interleaving data when they are writing concurrently.
I will be happy to submit configuration files if that is helpful.
Thanks
Volumes in red are the volumes bacula is now out of sync with. Every one of
these volumes is currently in a tape-drive. I have edited the output below for
simplicity in comparing mtx-changer command vs mysql select query.
Select VolumeName,Slot from Media order by slot; slot out put from
mtx changer --list all

Subject: Re: [Bacula-users] bacula can't make use of multi drives
OK, I was able to get this working.
One of the major factors was upgrading my version of bacula from 5.2.6 to 7.0.5.
It appears there is a bug in 5.2.6 in which bacula gets confused with regards
to which tape(volume) is in which drive and/or slot.
with 5.2.6, with my config files working, after backups ran for a few days the
slots no longer matched in bacula with what mtx-changer listall
told me from command line and I was getting lots of errors and backups hanging.
After upgrading to 7.0.5 I no longer had this problem and my backups are
running smoothly on 10 different drives using 3 different pools.
All is good for me here using multi drive configuration.
Thanks to Ana for extensive help to get this working.

Thanks for your reply.
My autochanger device definition in bacula-sd.conf is as follows. I removed
unrelated changer commands in Drive resource directives as you suggested, maybe
those direcives mess up bacula, I will see what happens.
Autochanger {
Name = AYKAutochanger
Device = Drive-1
Device = Drive-2
Device = Drive-3
Device = Drive-4
Changer Command = "/usr/libexec/bacula/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg9
}

In your Drives definitions, you don´t need to have Changer Device nor Changer

Thank you so much for your help with this.
I’m running test jobs now with the new setting and I’m 4 jobs from same pool

Again, your help is much appreciated.

Hi Jared,
Try setting
Maximum Concurrent Jobs = 1
in each device definition. This will spread your 4 jobs in 4 drives of your
autochanger device.
Device {
Name = Drive0
Drive Index = 0

# Enable the Alert command only if you have the mtx package loaded
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
SpoolDirectory = /etc/bacula/spool
Maximum Concurrent Jobs = 1
}

Ok, I’ve done some reconfiguring. Will paste my new configuration files below
as well as bconsole output from show pools, list volumes, status storage and
querying volumes per job. I am running 4 concurrent jobs to the same pool and
the writes are still interleaving data to the same volume.
I stopped and started bacula-sd, dir and fd, ran update slots scan before
kicking off these jobs. Status storage shows the new device names and things
are working, aside from the single tape being written to by all 4 jobs.
Still not sure where I’m going wrong with bacula and writing to multiple
volumes at the same time from the same pool. Currently the only way I’ve
achieved this with mixed results, i.e. success and failures, is with ‘prefer
mounted volumes = no.

# in the FROM field, which is by default the same email as they're being

# you'll have to set the FROM address manually, to a single address.
# for example, a 'no-re...@mydomain.com<mailto:no-re...@mydomain.com>', is
better since that tends to

Subject: Re: [Bacula-users] bacula can't make use of multi drives
Hi Jared,
In your bacula-sd.conf, you have defined an autochanger device:
Name = Autochanger
Device = Drive-1, Drive-2, Drive-3, Drive-4, Drive-5, Drive-6, Drive-7,
Drive-8, Drive-9, Drive-10
...
}
But, in your bacula-sd.conf, you don't use it. Instead, you have a storage
definition for each of your tape devices, like the bellow one for the Drive-1:
Storage {
Name = Tape1
Address = backup # N.B. Use a fully qualified name here, not
localhost
SDPort = 9103
Password = “PASSWORD" # password for SD
Device = Drive-1
Media Type = LTO
Autochanger = yes # enable for autochanger device
Maximum Concurrent Jobs = 20
}
This way, you are not using an autochanger nor a group of devices, but stand
alone tape drives.
If you want to use the autochanger, in your bacula-dir.conf, you should have
just one storage definition for your autochanger, like (note that the Device
name in your bacula-dir.conf is the same as the Autochanger Name in your
bacula-sd.conf):
Storage {
Name =
Autochanger-sd
Address = backup # N.B. Use a fully qualified name here, not
localhost
SDPort = 9103
Password = “PASSWORD" # password for SD
Device =
Autochanger
Media Type = LTO
Autochanger = yes # enable for autochanger device
Maximum Concurrent Jobs = 20
}
Also, could you please confirm if the bellow definitions in your pools are
really working?
Pool {
Name = Default
Pool Type = Backup
Storage = Tape7, Tape8, Tape9, Tape10
...
}
Is it really possible to have more than one storage in the storage directive
definition above? Because I really think that the storage directive accepts
just one storage entry definition. And if you have defined an autochanger in
your bacula-dir.conf, so this should be something like:
Pool {
Name = Default
Pool Type = Backup
Storage = Autochanger-sd
...
}
Best regards,
Ana

For the sake of sharing information I am going to reply to this thread since I
am working on the same type of setup and experiencing similar issues.
I removed the setting ‘prefer mounted volumes = no' and separated my jobs into
3 different pools. All my jobs are running smoothly now, no failures. The
prefer mounted volumes was the issue.
Now I am experiencing interleaving on a single volume/tape drive with multiple
jobs scheduled at the same time, in the same pool, as opposed to bacula using
different volumes and different drives for jobs scheduled at the same time for
the same pool.
Here is my issue:
I have 10 jobs that kick off at the same time every day. Each job takes
anywhere from 10 minutes to 2 hours. The pool behind these jobs has 4 tape
drives and 4 volumes(virtual tapes) assigned to it. The 10 jobs all kick off
at the same time and they all write to the same volume, apparently(assuming)
interleaving the data. See my paste below, Ive bolded start times, end times,
pools and tapes. One can see these jobs all completed near each other and ran
for over an hour. All to the same tape/volume, tape3 and volume AAAACF5F6A .
I assume if I had the "prefer mounted volume=no" for these jobs they would use
all 4 drives in the pool and write to separate volumes as opposed to
interleaving to a single drive and volume. But based on the manual, reported
problems and experienced problems with ‘prefer mounted volumes = no’ I hesitate
to use that.
My question:
Is there another way to get multiple jobs scheduled at the same time to run
concurrently using different drives and volumes, as assigned to the pool,
versus all writing at the same time and interleaving the data to a single drive
and volume even though the pool has 4 drives/volumes assigned to it? Or is
prefer mounted volumes = no the only way to solve this?
any help is greatly appreciated

Subject: Re: [Bacula-users] bacula can't make use of multi drives
I think that the only problem with setting "Prefer Mounted Volumes = no" is
that it will result in a lot of moving of a volume back and forth between
drives. While it might not be a bug, since it works as advertised, it CAN be a
problem. For tape, it will really slow things down because it takes a
substantial time to move a tape out of one drive and into another. For disk
virtual autochangers, though, the moving between "drives" is simply closing a
disk file and then re-opening it, meaning that the delay is very negligible.
Mr. Fisher: It's not just that. Eventually "Prefer Mounted Volumes = no" messes
up the autochanger during a random backup and you have to restart storage
daemon and sometimes powercycle the tape library.
If there is some other issue, like a race condition that I am not aware of,
then that would indeed be a bug in my book. But I have used
PreferMountedVolumes=no for disk virtual autochanger without (so far)
encountering any such problems, just the swapping between drives. And for disk
virtual autochangers, I don't see that as a problem in and of itself.
I don't know if it is already fixed or if this error happens for all
autochangers. But last Bacula System Community Storage whitepapers goes in the
same way. Having 2 pools is still safer and more reliable way to do multiple
volumes writing.

It's not a bug, but just the way it's designed.
"Prefer Mounted Volumes=no" it's a directive that could allow to write multiple
volumes within the same pool at the same time, however this is a little buggy
and not recommended at this time.

then that would indeed be a bug in my book. But I have used
PreferMountedVolumes=no for disk virtual autochanger without (so far)
encountering any such problems, just the swapping between drives. And for disk
virtual autochangers, I don't see that as a problem in and of itself.
