Hi,
i think all of you are right, but...
lets state a few things amanda does:
1.) you amlabel your tapes for use, and amanda put's them with
a date of 0 in its tapelist.
2.) the date of 0 in tapelist means: this tape has never been written
a backup to, it is a so called "new tape".
3.) amanda will accept a new tape at any point of the dump-cycle,
the numbering or position in tapelist does not care.
Tapes with date 0 will always stay at bottom of tapelist, in the
order they where labled in.
4.) when amada has writen the first backup to a new tape, it gets moved
with the correct date to the top of tapelist.
5.) at the point amanda has written a backup-image to as many as tapecyle
tapes, she will start to ask for the tapes she had used, in the order of
first date, second position, in the tapelist.

I thought amanda would just read from the bottom of the list.

Nope, amanda goes by date first.  List position is only significant
when 2 or more tapes have the same last-used date.


When it
was done with tape 009, 010 was at the bottom of the list and was used.
Now 010 is done, and 011 is at the bottom of the list.  Why isn't it
just taking that, instead of "trying to read my mind"? :-)

Just a guess, but I'd say it's because "0" is not a valid date, so
those lines are being ignored completely.


Those lines are what results when you amlabel a tape.  If your
surmisation was correct, amanda would never use any tapes.
