Hi,
I'm new to bacula.
I looked in the manual and the mailing list but didn't find a solution.
I'm using bacula 1.36.3 on a debian sarge system. Connected to the
system is a exabyte 221L with one IBM LTO-1 drive.
I got jobs scheduled which run fine. When there is no tape in the
drive it loads the tape. But sometimes when a job starts it keeps
waiting for a tape in the drive (there isn't one) and fails after a
while saying:
<message>

open device /dev/nst0. ERR=dev.c:289 stored: unable to open device

job.c:1665 Bad response to Append Data command. Wanted 3000 OK data
, got 3903 Error append data
</message>
It didn't issue the 'mtx-changer loaded' and 'mtx-changer loaded'
commands, which, i think, it should have.
Anyone an idea why this is done?
That might be because you're runing a linux kernel 2.6. The tape access
there ahs changed quite a bit compared to 2.4 and standard unix
behaviour which can result in the SD not being able to access tape
drives without a tape loaded - just what you observe.
If that's the reason for your problem an upgrade to 1.38.5 might be your
best solution. I don't know if there are debian packages available, but
apart from that, an upgrade will improve some functionality and result
in better stability in many cases.

Hi,
I compiled 1.38.5 and installed it in a directory. I changed
bacula-sd.conf so that it used the new tapechanger resource. I still
have the same problem. I must be doing something wrong, but don't know
what. Do you?
The first job starts and when finished it unloads the tape (with
runafterjob command)-->backup OK
The next job starts loads the same tape and when fininshed it unloads
the tape-->backup OK
The next job starts loads the same tape and when fininshed it unloads
the tape-->backup OK
The Catalog job starts and outputs the following messages. This time i
got to mount the tape myself (tape VR0801L1 is in changer slot 8).
After manually loading the tape (with mtx) and mounting the device, the
backup is continuing and is OK. The only problem is 'why do i have to
load and mount the tape'.
