bacula-sd blocks the drive so bscan cannot get the access.
umount normally release the tape and then the tape will be unloaded to
the related slot.
bacula must not run at all if bscan is working. You need only a running
database engine.
As I remember if you run a bscan with a couple of tapes (the written
tape order should be the same as for writing as I remember the jobs
which overlaps from one to another tape possible will not be correct
written to the database, but I'm unsure) the first tape must be
loaded by the changer so you can use mtx to load the first tape and
then use mt to check the status.
After loading bscan should run. It is a good idea to run bscan in
very verbose mode and write the log to a compressed file because
it will become very large uncompressed like

bscan . 2>&1 |gzip >logfile.gz

In another terminal session you can check the file with zless logfile.gz,
but i think following will not work so you can check file from time to
time by restarting zless and jump to the end with >.

I hope my 2-cents are not false informations. It's a longer time
that I used bscan (a couple of month?).

Cheers,
Pierre

Oh, mayhap something has changed, I haven't run bscan since, um, last 
decade?  But I have been caught by the drive locking from time to time  :-)

Not weird, the Bacula SD locks the drive when told to mount a tape, so 
it needs to be unlocked for anything else to use it.


As bscan is stand-alone, not something that drives the SD, it needs the 
tape unlocked.


Having Bacula umount the tape also means that the Bacula scheduler can't 
come along and bugger things up.

[Bacula-users] bscan cannot open my tapes - help!

2020-05-29 Thread Nico De Ranter 
Hi all,

2 months ago my postgres database got corrupted. As a result I am not able
to dump the database anymore.  All other functionality still worked, only
the backup of the Bacula catalog failed every time.  As I could not fix the
Postgresql issue I decided to reinstall the database from 2 months ago and
then use bscan to scan all tapes since.  Unfortunately when I try to run
bscan it asks me to load a certain tape, however that tape is already
loaded and 'status slots' shows the right tape is available in the jukebox
and loaded in the drive.  bscan just sits there and doesn't seem to be
doing anything.   How can I convince bscan to start reading the tapes?

Bacula version:  9.0.6
OS version: Ubuntu 18.04.4 LTS
Tape device: Quantum Superload 3 with LTO-6 drive

What I tried:
- dropped the old bacula database, recovered the latest usable database
from tape and installed it
- verified using bat that bacula is still running and I can see all data
(up to 2 months ago ofcourse)
- created a .bsr file containing a list of the volumes I want to scan
- bacula-dir, bacula-sd and bacula-fd are running on the server

when I start bscan as follows:

bscan -s -m -c /etc/bacula/bacula-sd.conf -v -b bscan-recover.bsr /dev/nst0

It says:

bscan: butil.c:292-0 Using device: "/dev/nst0" for reading.
29-May 13:43 bscan JobId 0: No slot defined in catalog (slot=0) for Volume
"MG3119L6" on "Superloader-Drive" (/dev/nst0).
29-May 13:43 bscan JobId 0: Cartridge change or "update slots" may be
required.

According to the console the tape is available and mounted

*status slots
Automatically selected Storage: Jukebox
Connecting to Storage daemon Jukebox at backup.office:9103 ...
3306 Issuing autochanger "slots" command.
Device "Superloader" has 8 slots.
Connecting to Storage daemon Jukebox at backup.office:9103 ...

What am I missing?
