Re: [Bacula-users] DVD Backup Version 2.0.2 OK?

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?

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. 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?

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.

Many thanks in advance

Nils

This is the debug output from the director:

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.
