Late last week, amanda started to consistently produce reports such as
the following:
----- Forwarded message from backup <[EMAIL PROTECTED]> -----
*** THE DUMPS DID NOT FINISH PROPERLY!
*** A TAPE ERROR OCCURRED: [[writing filemark: Input/output error]].
*** PERFORMED ALL DUMPS TO HOLDING DISK.
THESE DUMPS WERE TO DISK. Flush them onto tape Daily01 or a new tape.
Tonight's dumps should go onto 1 tape: Daily02.

So, first off, the big question: Why is amanda first claiming that it
ran out of tape, then saying that only 27.3% of the tape was used?
Second, the taper stats read "N/A N/A" for all drives that were dumped.
This would seem to indicate that nothing was actually written to the
tape, wouldn't it? And, based on that, am I correct to infer that it
would be better to amflush last night's dumps onto the same tape instead
of advancing to the next one as instructed by the report?
And, finally, how do I actually debug and fix this?
Thanks, and more information is available on request, of course, just
tell me what would be useful.
