I too am trying to get DVD burning working, following Richard
Mortimer's "tricks and tips" page.
I've been able to get a job of about 65 MB to write to DVD OK. The
problem I'm having is
with a job that's about 9 GB. As you can see I set the SpoolDirectory
to /tmp/backup,
but I don't have 9 GB free in there. My reading of the
MaximumPartSize setting is that it's
supposed to finish one "part", then write it to DVD, then delete it
from the spool directory
before writing the next "part". That's not happening - more and more
"parts" are created
in the spool directory and it fills up (at least, I let it get very
close before cancelling the job because
it's in /tmp). If I cancel the job after about five or six parts have
been created, the storage
daemon writes the _last_ part to the DVD and deletes it, leaving the
others in the spool
directory.
As you can see I tried the MaximumSpoolSize and MaximumJobSpoolSize
settings as well,
but they didn't do anything and I now have them commented out. I
don't have spooling turned
on anywhere else (or in the director).
I turned on debugging of the storage daemon. It seems it is not that
the daemon is trying
and failing to write a part to the DVD - it is not even trying. So
I've been wondering if
my understanding of MaximumPartSize is wrong.
