(Sorry, I couldn't resist.)
So, I have to confess that I've used AMANDA in other settings for a long time
without knowing how to address this particular issue correctly (i.e., in a way
that doesn't require periodic intervention). What I've found via web searches
always seems to indicate a simple math error, but when I compare the config
comments and manpage to my running config, it seems like I shouldn't run into
this.
What I'm looking for is a four-week cycle, with backups running 7d/w. (I'm
backing up, over the Internet, a free colo granted to me by my old company, and
don't want to be a pest w/r/t bandwidth by pulling down fulls every week.) I
initially labeled 20 tapes because my cycle was originally going to be two
weeks, but added 20 more later, when I altered my plan. So, 40 tapes. I've now
fallen off the end of the cycle, and AMANDA won't reuse what she's got:
*** A TAPE ERROR OCCURRED: [No writable valid tape found].
Some dumps may have been left in the holding disk.
Run amflush again to flush them to tape.
The next tape Amanda expects to use is: a new tape.
When I check the /etc/amanda/<config>/amflush.1 logfile, it appears to step
through all the tapes, reading the labels:
...
slot 1: read label `NOISEPLANT-1', date `20090609'
slot 2: read label `NOISEPLANT-2', date `20090611'
...
slot 40: read label `NOISEPLANT-40', date `20090506'
and then throws this, which itself contains the whole "tape-label-read list" in
square brackets:
driver: result time 2.791 from taper: TAPE-ERROR [slot 1: read label
`NOISEPLANT-1', date `20090609'
slot 2: read label `NOISEPLANT-2', date `20090611'
...
slot 40: read label `NOISEPLANT-40', date `20090506'
]
I'm really sorry to be the nth person to ask this, but I think my setup
reflects the answers I've read to many similar, previously-addressed questions
(in that (runspercycle * runtapes) < tapecycle). So: Is something else at
issue? Any clues as to what I am doing wrong? Context follows:
