Hello all;
after getting last weeks issues fixed, downgrading amanda
(now 2.5.0-20060424) as well as tar (now 1.14-2.2), Thursday and Friday
incremental dumps worked out. However, weekend dump once again didn't
to as it is supposed to. I had an eye on the amanda processes all the
weekend and it _seemed_ fine, but in the end it ain't. Some excerpts
and log dumps:
- according to amstatus, nothing has been written to tape:

- Likewise, amverify (could this input/output error be caused by a
defective drive / tape or is this just the result of the tape being
empty?):

actually calculate the size of the DLE in question?

- sendsize, again, is filled with error messages like those below, even
though the files definitely are around and usually an arbitrary
application also is capable of opening / reading them without a problem.

Again, same questions - hardware error? Tape error? Misconfiguration?
Right now, I tried to manually dump some data to the drive, ending like
this:
backup:/tmp# tar czvf /dev/nst0 /backup/PV/
[...]

tar: /dev/nst0: Cannot open: Input/output error
Ideas, enlightenments, hints, ... really much appreciated... :/
Thanks and bye,
Kristian
