IF the right tape is already loaded.
Sounds weird, but its true. Now, I'm going to back up one amanda
snapshot at a time and see if I can find what snapshot broke it.
Basicly, if the tape it wants is in fact loaded into the drive, then
amcheck nor amdump (& probably amflush too) cannot find it. Here is
the mail from an amcheck run at 4pm, and I had the correct tape for
tonight already loaded when cron ran amcheck again, returning this:

So, I rerun amcheck, it finds the tape in slot 3 just like its
supposed to.
Curious george here smells a rat, so I reran it twice more, getting
this:

I can repeat this till I've worn out the tapes it appears.
Next, since I've got these src dirs with amanda already built:
amanda-2.4.4p2-20040129 amanda-2.4.5b1-20040323.tar.gz
amanda-2.4.4p2-20040129.tar.gz amanda-2.4.5b1-20040326

amanda-2.4.5b1-20040323
I'm going to reinstall older ones till it works. Starting with 0316.
That failed, then I have a gap as I was out of town, so the next one
back is 0213, and it also failed. Next back is 0202. And that one
failed to read the tape already left loaded by a previous run. Now
to try 2.4.4p2-20040129... And it also fails & thats as far back as
I can go with whats on hand.
I'm seeing a pattern here, but its spotty. Going back to the latest
snapshot for now, and to play with the chg-scsi.conf sleep time
value, currently at 20 seconds, tried 60 which appears to be a total
failure. Been using 30 for years. This was being a problem before I
put in the newer changer, but I was blaming the changer then because
a cleaning tape run would fix it for a short time. This one is not
telling me its dirty by way of the front panel.
This is enough for one night, any ideas from anyone, or some help from
Thomas Hepper, who was the last to walk around in that code that I
know of, would be nice.
