I have NetWorker on Linux using an Adic FastStor DLT jukebox with a single
DLT7000 drive. NetWorker will move the tapes between the drive and the slots
just fine when I tell it to, however when it reaches the end of a tape
during a backup, it won't move it out of the drive and load the next one.
What version of Linux and Networker?
Kernel version is 2.6 and Networker 4.1.4 build 562.

Annoying. Is anything logged when this happens? Is the tape drive
still "open" by a nsrmmd process (check with fuser or lsof)? Does the
tape at least appear to rewind, or does it do nothing?
I can't tell if the drive is still open because I've already unmounted it to
continue my backups, but here is a snippet of the log:
(warning) /dev/nst0 writing: No space left on device, at file 106 record 5732

I'm assuming that the tape is rewound based soley on the fact that when I
unmounted it, the jukebox didn't have to rewinde it before placing it back
into a slot.

I have "Auto media management" set to yes in the jukebox config window,
which sounds like it should do what I'm asking for, but it doesn't.
It doesn't have anything to do with what you're describing. optional
verification, followed by rewinding, ejecting, unloading, and reloading
should all be normal activities that don't have to be "enabled".

Anyone have any ideas?
If you have a tape in the drive, but moved forward, does asking
networker to unload still work, or is it only during a backup that it
fails?
If I unmount a tape which has been partially used, it will eject it and
place it back into a slot. It only seems to be during a backup, when the
current tape is filled, that the drive doesn't automatically unmount and
eject the tape and move to the next one.
It may be worth noting that I configured the jukebox as a "Standard SCSI
Jukebox" at scsidev < at > 0.1.0 with the tape drive itself at /dev/nst0. I was
able to "excercise" it according to the manual and was also able to label 5
tapes (all I had loaded at the time) from slots 1-5.
Thanks,
Roy
