Hello,

Again: Did you tested your tape drive with btape utility? For me it is a misconfigured storage device.

best regards

Hello,

The recommendation for Bacula versions are:

director = storage daemon >= file daemon

It seems you have your director and storage daemon running 5.2.5 version and client running 5.2.10. Also, is your system 32 or 64 bits?

Best regards,
Ana

Hi Everyone,

I have issue writing to my tapes.

I have an HP tape library connected to ubuntu 12.04 with bacula 5.2.5
installed.
when I am running a full backup job on any client or with any tape (tapes
are new, so its not tape issue)
the job stops in the middle after the SD wrote about 20GB than mark the
tape as FULL and throw those errors:

   Changer Device  = /dev/sg3
   Changer Command = "/etc/bacula/scripts/mtx-changer %c %o %S %a %d"
}

the backup succeed but with two new volumes(tapes), but it should succeed
with one tape
the tape is LTO5 1.5T capacity so I don't understand why it stops around
20GB and also can't position to the end of data for previously written
tape.
I cleaned the drive several times but it still occurs, any idea what the
cause? hardware issue? software issue?

Kind Regards,
Roi,
