Hi,
I'll add some comments here I cannot guarantee that they all apply to
2.4.x because I'm still using 2.2.x and haven't been tracking
development that closely for well over a year. That said I did have DVD
writing working and many of the errors that you report do look familiar.

Hi John, hi everyone!
I think I am getting closer to get DVD-burning to work. I would really
love to use this feature and I would be glad to help fix it.
I just checked, I had dvd+rw-tools-7.0-0.el5.3.rpm installed. As this
is is <7.04 I uninstalled the rpm and compiled / installed from this
sources:
http://fy.chalmers.se/~appro/linux/DVD+RW/tools/dvd
+rw-tools-7.1.tar.gz
Now, growisofs is version 7.1:
* growisofs by <appro AT fy.chalmers DOT se>, version 7.1
Does this version still require patching before building?
I used the Debian version that already had the patches applied.
Here is what happens now: DVD burning works AS LONG as bacula doesn't
write more than one part. After the first part a mount error occurs. I
think that bacula for some reason tries to mount the dvd after each
part, maybe to check what it just wrote or to calculate the remaining
space.
It does try to check how much space is left.
The mount failure isn't necessarily a problem doing the operating system
mount of the DVD but rather that Bacula didn't find when it expected or
maybe that it tried to open a file on the DVD in read/write mode.
As far as I understand, it is NOT safe to burn parts > 800MB to a dvd
so I left the default value of 800M in bacula-sd.conf.
I ran the SD as root (/usr/sbin/bacula-sd -d 99) so I don't think that
there really is a mount error. Maybe the debug-output is misleading?
Yes I agree. See what I wrote above.
You will find the (somewhat lengthy) debug output of DIR and SD
attached.
If ANY other information (versions, configurations, hardware etc.)
might help solve the issue, please ask. I will provide you with
anything needed asap.
I don't have time to look too closely at the moment but the following
may help.
First off I always found that I needed to comment out the following line
in the /etc/bacula/scripts/dvd-handler script.
growcmd += " -use-the-force-luke=notray"
Add a # at the start of the line to make it
# growcmd += " -use-the-force-luke=notray"
This is because linux does (did?) not re-read the disk geometry
automatically. The above line forces the DVD to be ejected after writing
and the mount reloads it causing the OS to re-read the geometry and find
the new data written to the DVD.
I actually think that this is the problem that you are seeing because
without it the OS will report unreadable blocks when doing the low level
mount command.
You may also find it useful to go through the steps in
http://bridge.oldelvet.org.uk/bacula/BaculaDVDSetup.html
If those steps are not all successful then Bacula has very little chance
or correctly writing to the DVD.

Richard
Many thanks in advance

Hi all together,
and, sorry for my english :)
I read that version 2.0.2 is running fine for DVD
Backups. I tried with 2.4 and 2.2.8 both are buggy.
Did you use a patched dvd+rw-tools? Or a 7.04 or
greater?
John
I have patched dvd+rw-tools on latest Debian. And I can confirm that both the 2.2.8 and 2.4 branch do not work.
