[Bacula-users] Fwd: RE: Automatic Volume creation

Hi,

I have Bacula running with an IBM TL3400. As the tapes are bar coded

Bacula can read the library and add the tapes to it's catalogue. I can

than move then to the backup pools. My issue is the tapes have not had a

volume written to the front of the tape using the label command they

fail to mount with the following bconsole status.

Device "Drive-3" (/dev/nst2) open but no Bacula volume is currently

mounted.

    Device is BLOCKED waiting for mount of volume "CBP10020",

       Pool:        snapshot-pool

       Media type:  LTO-3

    Slot 11 is loaded in drive 2.

    Total Bytes Read=0 Blocks Read=0 Bytes/block=0

    Positioned at File=0 Block=0

Tape CBP10020 is in /dev/nst2 but is blank. How do I get Bacula to

automatically initialise the tape and write the volume label. My storage

definition is as follows:-

From what I know all you need is one command to label all the tapes with their barcode. Or as the manual reads:

If your autochanger has barcode labels, you can label all the Volumes in your autochanger one after another
by using the label barcodes command. For each tape in the changer containing a barcode, Bacula will
mount the tape and then label it with the same name as the barcode. An appropriate Media record will
also be created in the catalog. Any barcode that begins with the same characters as specified on the
”CleaningPrefix=xxx” command, will be treated as a cleaning tape, and will not be labeled.

I sort of assumed that AutomaticMount would do it. I am reluctant to use

LabelMedia because I am not sure it will use that label on the bar code

rather than issuing a new one. Can anyone confirm that behaviour of

LabelMedia when used with a bar coded auto-changer?

I don't think you'll need LabelMedia as that would indeed label the tapes with a label as specified by the LabelFormat directive you'd put in there with it. The command above should achieve what you want.

More on autochangers in Chapter 31 of the manual :)

Bacula was set up to periodically read the auto-changer catalogue. As a result media records existed for the unlabeled tapes. Tapes with a media record are overlooked by “label barcodes”. The other issue I had was when I tried it threatened to label all the tapes and assign them to one pool. It did not explicitly mention that is would ignore tapes with an existing media record. I will now think about the automatic read of the tape library and change it to sweep new tapes into the scratch pool.

Thanks Rob
