Excellent. Good to know you are sorted.

Just to clarify, I do mean DVD-RAM . A ROM would be Read Only (hence the O)

It's different to DVD-RW & DVD+RW and there is a bit of discussion on a Wikipedia page : DVD-RAM - Wikipedia
To get it all to work, we had to make a mksysb image on a local disk and then use mkdvd appropriately. Oddly it eventually calls readcd with the write flag set, but you probably won't need to worry about that. It did need a chunk of free space in the rootvg too, just over twice the size of the mksysb image. I also had to adjust the LV creating algorithm in mkdvd (I think) because it estimated too small and we were continually running out of space in the temporary LVs it creates.


Is there anything else we can try to help with?

Ignoring that rootvg also creates files needed to boot a system... (1 Reply)

BACKUP_DELVOLSET(8)					       AFS Command Reference					       BACKUP_DELVOLSET(8)

NAME
backup_delvolset - Deletes one or more volume sets from the Backup Database SYNOPSIS
backup delvolset -name <volume set name>+ [-localauth] [-cell <cell name>] [-help] backup delvols -n <volume set name>+ [-l] [-c <cell name>] [-h] DESCRIPTION
The backup delvolset command deletes each volume set named by the -name argument, and the volume entries each contains, from the Backup Database. The backup listvolsets command lists the volume sets (and their volume entries) currently defined in the Backup Database. CAUTIONS
Deleting a temporary volume set is possible only within the interactive session in which it was created. Exiting the interactive session also destroys the temporary volume set automatically. OPTIONS
-name <volume set name>+ Names each volume set to delete. -localauth Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The backup command interpreter presents it to the Backup Server, Volume Server and VL Server during mutual authentication. Do not combine this flag with the -cell argument. For more details, see backup(8). -cell <cell name> Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see backup(8). -help Prints the online help for this command. All other valid options are ignored. EXAMPLES
The following command deletes the volume set called user and all volume entries in it: % backup delvolset user PRIVILEGE REQUIRED
The issuer must be listed in the /etc/openafs/server/UserList file on every machine where the Backup Server is running, or must be logged onto a server machine as the local superuser "root" if the -localauth flag is included. SEE ALSO
