Hello list!
I am running bacula 2.4.2 from fschwarz's EL5 rpms on CentOS 5.2
I am having a hard time getting bacula to write backups to DVD. I have
narrowed it down to the following:
After burning a part to DVD, bacula mounts the volume to determine the
used space and pass the result to growisofs.
This mount fails and the used space is not determined correctly (I guess).
My mount command (from storage definition) is:
"/usr/bin/sudo /bin/mount -t iso9660 -o ro %a %m"
I can mount and unmount the dvd-writer as user bacula with
"/usr/bin/sudo /bin/mount -t iso9660 -o ro /dev/dvdwriter-hda
/mnt/bacula-dvd" without any problems.
The same error occurs when I do not use "/etc/init.d/bacula-dir start"
to start the sd but instead run "/usr/sbin/bacula-sd -d 99" as root.
I really can't see why bacula should NOT be able to mount the device. I
cannot reproduce this error on a shell as user "bacula". Plus the exact
same error happens when I run the sd as root. Maybe the output is
misleading?
I am quite stuck here. Any help would be greatly appreciated!
Thanks in advance
Nils
My configuration (If any other info would help, please ask):
This is my dvd-tools version:
dvd+rw-tools-7.0-0.el5.3
I read that dvd+rw tools have to have a bacula-patch incorporated. I
don't know if my version does so and to be honest I don't know how to
find out...
I don't know if it matters but I am using "Platinum 16x DVD-R 4.7GB"
media (I have tried DVD+R media as well, no luck).
This is the storage definition:
Device {
Name = "DVDWriter"
Media Type = DVD
Device Type = DVD
Archive Device = /dev/dvdwriter-hda
LabelMedia = yes; # lets Bacula label unlabeled media
Random Access = Yes;
AutomaticMount = yes; # when device opened, read it
RemovableMedia = yes;
AlwaysOpen = no;
MaximumPartSize = 50M; # decreased partsize to reproduce error
more quickly (should be 800M)
RequiresMount = yes;
MountPoint = /mnt/bacula-dvd;
MountCommand = "/usr/bin/sudo /bin/mount -t iso9660 -o ro %a %m"
UnmountCommand = "/usr/bin/sudo /bin/umount %m"
SpoolDirectory = /tmp/backup;
WritePartCommand = "/usr/lib/bacula/dvd-handler %a write %e %v"
FreeSpaceCommand = "/usr/lib/bacula/dvd-handler %a free"
}
This is the job's output:
