Hi,
I have DVD's working almost well in my setup. The problem is that I can
not reuse a DVD volume because bacula mounts the DVD (to ensure that it
is the right dvd to write to?) before writing, and it does not umount it
again before the actual writing. My device is unable to write if it is
mounted, it complains with these messages:
Error trying to open /dev/hdc exclusively ... retrying in 1 second.
Error trying to open /dev/hdc exclusively ... retrying in 1 second.
Error trying to open /dev/hdc exclusively ... retrying in 1 second.
Error trying to open /dev/hdc exclusively ... retrying in 1 second.
[...]
And the writing finally fails.
This way, I can only do one backup per DVD volume, which is a strong
limitation.
I added this line to the beginning of the write() method in the
dvd-handler to fix this situation:
os.system("sudo /bin/umount /dev/hdc")
And now it appends data to existing DVD volumes just nice.
I imagine that this is not the best place to put this command (besides
it's an ugly hack that only works at this machine), but it solves the
problem a lets us use bacula with complete functionality in production
for DVD's also.
May I enter a bug in the tracking system for this issue?
Thanks.
