Hi Amihai

this looks like a very weird error.  Could you execute the btape command again but with debug level 1000 ? I.e.

btape -d1000 --verbose /dev/IBMtape0n

The output of this would be very helpful when trying to track down your issue.

Kind Regards
Sebastian Sura

I try to write an eof mark on one of the problematic tapes.
I try with one tape:
/mt -f /dev/IBMtape0n eod/
/mt -f /dev/IBMtape0n weof/

now I try to check with btape but gets an error:

/btape  /dev/IBMtape0n/
/*status
 Bareos status: file=0 block=0
 Device status: BOT ONLINE file=-1 block=0
Device status: TAPE BOT ONLINE. ERR=
*eod
btape: stored/btape.cc:627-0 backends/generic_tape_device.cc:207 ioctl MTIOCGET error on "tapedrive-0" (/dev/IBMtape0n). ERR=Success./

Is there any bug in the *generic_tape_device.cc* code ?
Thanks, Amihai

        I have set in the Pool:

        Maximum Volume Jobs = 0
        or
        Maximum Volume Jobs = 100

        But when a backup starts on the tape device, I get the messages:

        Max Volume jobs=1 exceeded. Marking Volume "000017L9" as Used.
        Max Volume jobs=1 exceeded. Marking Volume "000016L9" as Used.

        How can this be solved?
