On a Bacula server running openSUSE 11.4 and Bacula 5.0.2
I have replaced the previous LTO-1 drive by an LTO-2 one.
The LTO-2 drive can read and write LTO-1 tapes, and so I
naively assumed I should be able to continue using my old
tapes without further ado.
Not so. When I mounted the current backup tape in the new
drive, Bacula insisted:
Cannot find any appendable volumes.
Please use the "label" command to create a new Volume for:
Storage: "LTO-2" (/dev/nst0)
Pool: Daily
Media type: LTO-2
The mounted tape was in pool "Daily" and state "Append", but
still Bacula refused to use it. The only difference was that
it had media type "LTO-1" and Bacula requested "LTO-2".
I then purged and relabeled it, losing all the backups on
it. Purging alone did not help, but after relabeling, Bacula
listed it as media type "LTO-2" (even though it is of course
still an LTO-1 tape) and willingly wrote the waiting backup
to it.
- Am I right to assume that it was the difference in the
media type which caused Bacula to refuse that tape?
- What is the rationale behind that behaviour?
- What would happen if I tried to restore with the LTO-2
drive one of my old backups written with the LTO-1 drive?
Would Bacula refuse that too?
- If I connect two LTO drives of different levels to the
same Bacula server, is there a way to use the same tape
alternatingly in both drives as supported by the
hardware? (*without* losing the data on it, that is)
Thanks,
Tilman
