[Bacula-users] automount with single non-autoloader drive

[Martin S. <ms...@ha...>]

has someone managed to use automatic mount and unmount just by configuring
the storage daemon the 'right' way with a bacula 2.0.3 (maybe on Debian
Linux)?

The goal is that the media change shall be sufficient for the normal 
backup to work. No manual intervention at all shall be needed.

The closest I get is that tape gets ejected automatically when a new or
specific tape is needed. When I then insert the right tape, it gets
recognized at the next poll interval, which I have set to 3 minutes, but it
doesn't get mounted. Bacula then says that there is a tape in the drive 
and the
drive is open, but it is not recognized: 'open but no Bacula volume is
currently mounted.'

Why does the 'Automatic Mount' not work when the device is opened at a poll?

Or, is it a known bug?

I've tested with several tape drives of several brands but all were DAT.
I've also tested on several servers but only with bacula 2.0.3. An I don't
have a changer.

I know that there were approaches using simulated changers with bacula 1.38,
but I'd prefer something less limiting...

My conf for the device:

Device {
Name = DDS-2 #
Media Type = DDS-2
Archive Device = /dev/nst0
Automatic Mount = yes; # when device opened, read it
Label Media = yes; # lets Bacula label unlabeled media
Always Open = yes;
Removable Media = yes;
Random Access = no;
#Maximum Changer Wait = 3d # 3 days in seconds
#Changer Command = "/etc/bacula/scripts/ak-mtx-changer %c %o %S %a %d"
#Changer Device = /dev/nst0
Offline On Unmount = Yes; # keep this too
Volume Poll Interval = 3m
#Close on Poll= Yes
Maximum Open Wait = 3d
#Auto Changer = yes
# Enable the Alert command only if you have the mtx package loaded
#Alert Command = "sh -c 'tapeinfo -f /dev/nst0 |grep TapeAlert|cat'"
#If you have smartctl, enable this, it has more info than tapeinfo
## Alert Command = "sh -c 'smartctl -H -l error %c'"
}
