Greetings,
For the past 4 weeks (and with 4 different tapes), I've been getting
the following errors while my backup is being flushed to tape:
*** A TAPE ERROR OCCURRED: [[writing file: short write]].
FAILURE AND STRANGE DUMP SUMMARY:

This to me suggests that Amanda "ran out of tape" after writing about
10131 MB, which is strange since (according to the following tapetype
definition in amanda.conf) the tape can hold well over 11000 MB.
define tapetype SEAGATE-DDS3 {
comment "Seagate STD224000N-SB Internal DDS-3 Drive"
length 11550 mbytes
filemark 0 kbytes
speed 1075 kps
}
The backup set that is experiencing these problems runs once a week and
had been working fine for over a month. The tapes that this set uses
are relatively new (about 2 months old) and were written to
successfully in the period before the "short write" problems surfaced.
Also, I have two other backup sets that run every weekday, and these
have been working without any problems at all. Moreover, one of these
well-behaved backup sets uses the same kind of tapes and the same
tapetype definition as the malfunctioning backup set. I also tried
cleaning the tapedrive, and still the problem persists.
I'd be grateful for any light that could be shed on this problem,
Thanks,
--Matt
