Dear Sirs.
For our 250 GBytes RAID array backup on a FBSD 4.3 Server we use
AMANDA 2.4.2p1. The tape changer is a HP SureStore 40x6i, which has
a 6 cartridges magazine.
I configured AMANDA that way to use the first time 8 magazines, each
holding 5 tapes and one cleaning tape. For all filesystems GNU tar
(GTAR) is used so I do not fall into problems when dumping images
bigger than one tape.
The first time this runs well, AMANDA saved all the images out to
two or three tapes (like the multi volume mechanism when using a
simple tar -M backing up a big filesystem ...). Now we changed
several parameters (due to the lacking docimentation how to use
GTAR we have had to recalibrate all parameters to the right size
and want to start from the begining).
amlabel labels each used cartridge used by AMANDA and in the manner
of using dump as the backup/save tool this means that each run is
made to tapes with increasing numbers.
At this moment, our magazines are filled up with cartridges each
labeled with the same label, means mag one is completely labeled
throughout each cartridge with LABEL00, the second mag's tapes
LABEL01 ... that means now, whenever GNU tar/AMANDA reaches the
end of the first tape to continiue on the next one, it finds
the same labeld tape in each slot, greps through the whole magazine
and tells that it is out of tape. Well, I'm not very familiar how
AMANDA/GTAR signs up each tape to keep in track with each one,
but I want it to have 'clean' tapes because I think gtar is
not continuing a LABEL00-tape on a second, like LABEL00:1, instead
it needs LABEL01 - tape, or I'm wrong?
How can I delete each label a fast way? ERASE is not a good idea
(using mt) due the fact it takes a long time for each tape to be
cleaned and delabeled ...
