[Bacula-users] Cannot use DVD for backup's, several errors. Help!

Robert Dhaene Thu, 01 Jun 2006 08:53:19 -0700

Hello all,

I am having a lot of trouble setting up Bacula to use DVD+RW’s for its backup media. Unfortunately I do not have the money for a home tape system, so I decided to go with DVD+RW’s. Here is what is going on. When I attempt to run a backup job the console requests that I mount a media volume (chdata1-0001, is the default setting for the first label per my config files listed below). Since it a blank DVD+RW I am unable to mount it. Also, I am unable to label it manually. This makes sense since you mount file systems not a drive. I am running Bacula version 1.38.9 with dvd+rw-tools version 5.21.4.10.8 patched with the provided Bacula source patch file. I am running Gentoo Linux Distribution. In my system log file I am receiving some interesting errors:

May 31 13:18:46 chdata1 Unable to identify CD-ROM format.

May 31 13:18:47 chdata1 Unable to identify CD-ROM format.

My DVD Writer does support the media I am using, and it has been formatted using dvd+rw-tools. I have also attempted to use DVD-R and DVD+R with the same result. The exact requests I receive in Bacula are as follows:

01-Jun 11:31 chdata1-dir: No prior Full backup Job record found.

01-Jun 11:31 chdata1-dir: No prior or suitable Full backup found. Doing FULL backup.

01-Jun 11:31 chdata1-dir: Start Backup JobId 8, Job=Client1.2006-06-01_11.31.22

01-Jun 11:31 chdata1-dir: Created new Volume "chdata1-0001" in catalog.

01-Jun 11:31 chdata1-sd: Please mount Volume "chdata1-0001" on Storage Device "DVD Writer" (/dev/cdrom) for Job Client1.2006-06-01_11.31.22

I then issue command:

*mount

Automatically selected Storage: DVD

3001 OK mount. Device="DVD Writer" (/dev/cdrom)

With this result:

*messages

01-Jun 11:32 chdata1-sd: Please mount Volume "chdata1-0001" on Storage Device "DVD Writer" (/dev/cdrom) for Job Client1.2006-06-01_11.31.22

Any help is greatly appreciated. I am now at a loss after a week of reading online. I am somewhat new to *nix, not to computers at all. I would consider myself on a scale of 1-10 on knowledge at a 4 with *nix with always more to learn :] .

Thanks. Below are config and log files.
