Hello Richard,
Here you have the device entry:
#
# A DVD device
#
Device {
Name = "DVD-Writer"
Media Type = DVD
Archive Device = /dev/hdc
LabelMedia = yes; # lets Bacula label unlabeled media
Random Access = Yes;
AutomaticMount = yes; # when device opened, read it
RemovableMedia = yes;
AlwaysOpen = no;
MaximumPartSize = 800M;
RequiresMount = yes;
MountPoint = /media/disk;
MountCommand = "sudo /bin/mount -t iso9660 -o ro %a %m";
UnmountCommand = "sudo /bin/umount %m";
SpoolDirectory = /disks/wks188d1/temp;
WritePartCommand = "/etc/bacula/dvd-handler %a write %e %v"
FreeSpaceCommand = "/etc/bacula/dvd-handler %a free"
}
But the mount and unmount commands from the bconsole works well with
DVD's. I've just tested mounting and unmounting a DVD from bacula and it
worked.
Thanks for your help!
