ok, that's clear

taper: retrying lore:/local/home/moshkow.0 on new tape: [writing file: No space left on device]

This is taper again.

I tried that same DLE that failed on the last tape (retrying lore:/local...).

With so little info from the OS I can't really tell what happened, so I'll
print the same guess again.  But actually I don't really know if I got to a
different amanda tape or not, I can't even tell you the name of the tape.
So you will have to investigate to determine what is happening.

so maybe this isn't a error message but just a hint...

Jon here again...
Anyway that is what I interpret taper's messages as saying.  And if I were
investigating those are the only ones you showed us that I would care about.

Now the questions are things like "is your tape bigger than 310GB" so it should
not have run out?

no, it's 200GB uncompressed, so 310GB is a reasonable value for running out of tape

 Should amanda have been able to find another tape, if yes,
why didn't it?  If no, why did it try?

yes, it should have tried and it did suceed:

USAGE BY TAPE:
  Label           Time      Size      %    Nb
  volume008       8:24  296941.8  149.2    39
  volume009       2:41   37701.0   18.9     4

so it switched to tape 9 and even wrote some data.
These were the last log entries (concerning taper):

----------------------------snap----------------------------------------
Could this "Broken pipe" have come from me killing the taper process after it got stuck? What a pity there's no timestamp...

Next time i will look into the log *before* i kill some process.

thanks a lot for your hints Jon,
Kai
