Re: Amanda's response to malfunction of tape library

What you expected is what happens when amanda has "no place" to put
the dumps. Your combination of holding disk total space available
and the percentage reserved for degraded mode (a config option defaulting
to 100% but which must have been set lower in your config) left
enough space available to do the normal dumps. If things had
continued and you reached the reserved percentage, then incrementals
only would have been done.
Thanks, Jon, I should have noticed that. I have a total of 600G holding
space, and last time this sort of thing happened (some time last year),
I adjusted my config a bit and set reserve to 15%. In the frenzy of
running around helping people get their equipment up after our power
outage, and dealing with my confused tape library, I forgot that I had
made that adjustment.

¿amshutdown?
Not among my "am" command line utilities. Not on the web anywhere
according to google either {google(amshutdown amanda)}.
I'm figuring I will probably implement NUT
(http://eu1.networkupstools.org/). But I will still need to know whether
there is a clean and recommended way to tell Amanda to terminate
operations immediately (accepting that ufsdumps will probably just hang).
Separate from that, I will have to figure out how to tell my library to
prepare for loss of power. I can do that from the front panel, but I'll
have to find out whether mtx or sonytape tool can do it from the command
line. It essentially involves rewinding and ejecting the tape and then
putting the arm in a neutral position.
Interestingly, on Saturday the 21st the campus will experience a series
of rolling power outages as they test the new (~16.5MW CoGeneration)
Central Heating Plant. We may just shut down for the day. At least we
know in advance, and I'll get overtime to babysit the servers. 8-)
