[Bacula-users] appending to a full tape?

2010-04-27 Thread IEM - network operating center (IOhannes m zmoelnig) 
hi all.

i'm running bacula 2.4.4 in a debian/etch environment (i know that it is
a bit outdated; but there is even one debian/sarge host that i cannot
really update...)

bacula is doing a nightly backup (full every 3 months or so, diff
every week, and incr every night) onto an autochanger (Quantum
SuperLoader3, btw)


due to some scsi resets, 2 of my daily pool tapes have been flagged as
Full even though they are virtually empty (e.g. 4% fill state).


my tape pool has settled nicely, to use (almost) all tapes in the
changer, and having to add a new tape just because two empty tapes are
flagged as full seems to be a waste of ressources.

since the tape in question are part of the incremental strategy, i'd
rather not purge them.

is there a way to manually force a tape to be appendable again?

in bat i see that i could change the volum status to anything, even
Append, but i want to make sure that this is a good idea.


thanks in advance.

No worries, 2.4.4 is also the one in Lenny :)

And it seems to me that is about the most stable version ATM
(although the Branch-5.0 GIT seems to be rapidly fixing the remaining
bugs). So for this once Debian long sta(b)le policy is for the good!

Strange, I would expect them to be marked Error (but I have not run
2.4.4 for long)...

You may want to look at:
http://www.bacula.org/5.0.x-manuals/en/problems/problems/Tips_Suggestions.html#SECTION0036
(or http://tinyurl.com/33jhblm if your MUA breaks the link)

There may be issue with number of files written (which would lead to
tape being marked as error again when bacula tries to write next job
to it)
