Dear Listers,
I have a general question concerning the vtapes mechanisms and vtape length.
I configured an amanda server ("minerva", amanda-2.4.5-2, SuSE 10.0) with
"chg-disk" and 14 slots.
In the beginning there are a lot of "lev 0 failed", obviously, because I am
dealing with >100G data and each slot has only 18G (to fit on tape later
on).
But where does the "lev 0 FAILED [out of tape]" comes from?. I thought that
amanda would calculate properly the relation between data and tapelength.
Thank you for any enlightenment of my poor spirit.
BTW: Great wiki and docs, thanks to all who spent effort, really helpful!
Cheers
Uwe
Additional info
--------------------
The report:
These dumps were to tape slot3.
*** A TAPE ERROR OCCURRED: [[writing file: No space left on device]].
Some dumps may have been left in the holding disk.
Run amflush to flush them to tape.
The next tape Amanda expects to use is: a new tape.
The next new tape already labelled is: slot4.
