Hello,
Frequently, bacula jobs stall on a 'waiting for a mount request'.
However, when I do mount the requested tape, it still doesn't run.
Wondering what I'm doing wrong here. Any ideas?
I've just been discussing this with HP, Overland and on the -dev list.
It's come up on this list a few times before, across several brands and
technology of tape drive.
It's _also_ come up on a couple of lists for other backup packages.
Use tapeinfo to check the drive's /dev/sg* and see what it responds with
Odds are good that your tape drive has "prevent media removal" set. Try
using "mt -f /dev/nst[drive] unlock", then mt eject and see if the tape
is released or if you get a i/o error.
A few tape devs have tried to blame scsi reservations but I don't
believe bacula uses reservations _and_ I also suspect that if it was the
case then 'mt fsf' wouldn't work.
I'm beginning to believe there's some generic problem with the way that
most tape drives respond to locking/unlocking requests.
(Interestingly: after using tapeinfo, the PMR seems to have been
unlocked.....)
Thanks for your time.
