chg-disk question
Greetings; I had to do an emergency main disk change over the last 2 days, and used rsync to copy everything to a new drive. It wasn't quite that easy cuz my dvd copy of F10 I was going to use to re-install grub from turned out to have had an early mortality, not the first time that spindle of 100 dvd's has bit me. So I had to go have a friend pull it and burn me a new copy, a several hour delay. Those red label HP dvd-r's aren't exactly top of the line IMO. Anyway, as I was editing my amanda.conf to let it use enough tapes to complete a level 0 tonight, I noted this a few lines away: tpchanger chg-disk # deprecated, use amanda_changer now. #amanda_changer chg-disk It seems to be working, but I wonder when it was that I added that comment? Which is it supposed to be for future compatibility? Thanks. -- Cheers, Gene There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Check amanda.conf(5) -- they're two completely different config parameters.

Maybe, but there is nowhere near enough info in that to allow the un-assisted
configuration of all that define amanda_changer {}. I saw someplace where
I should create a set of slot# directories in the /usr/local/var/amanda tree,
but there are none, its never been setup. My man-pages, installed with the
2.6.2-20091112 snapshot yesterday, are apparently _way_ behind in terms of
tutorial value. And yet its working. Where are the docs to let us take
advantage of these new features.
If this needs to be configured, it would be very very nice if amcheck nagged
us about it. As it is, it reports no errors. Except after changing runtapes
from 1 to 3 for tonight's run, I get this:

Please excuse my bad mood, I am about to go to the funeral home stare at
the urn a long time employee named Doug Butcher's ashes are in for several
hours make small talk with all his friends then head for the Moose at
about 6Pm for a Broken Circle ceremony finger food there. He made it to
44. Working for us at WDTV was pretty close to the only job he ever had.
His whole family has a history of shortened lives, his only sibling, younger
sister Letha has been gone for about 8 years already. Both his parents
passed in their early 40's too, heart failure too. Even pacemakers didn't
help extend him much, although he was implanted about 6 years ago so maybe he
got some free time. Neither Letha nor Doug had any progeny or partners.

I'm not sure what new features you're talking about -- from what I
can tell, you had a disk failure and did a recovery, checked your
config file and saw something that didn't look familiar (but was in
fact familiar), and deleted a space between runtapes and 3.
There's no such thing as define amanda_changer.
What are you trying to do?

Ok, I now see where I saw the mention of it, in the new example/amanda.conf,
it says:
==
tapedev tape:/dev/YOUR-TAPE-DEVICE-HERE # tape changer or device to
use
# To use vtapes, create some slotN directories (slot0, slot1, etc.) under
# /var/amanda/vtapes and use this tapedev:
## tapedev chg-disk:/var/amanda/vtapes
==
Now, I can do the above, and I also assume I can move them to
/usr.local/var/amanda, (and that this does not effect my present location for
the vtapes themselves, which is a separate 1 terrabyte drive mounted to
/amandatapes, ) where amanda keeps some other records also, but then what do
I do with the tpchanger setting? You say its unrelated? It is not used in
the new amanda.conf except inside a definition, but mine is not inside a
define {}.
That original advice did come from this list, but my corpus of old messages
doesn't reach back that far as it was at least a year ago, maybe even 2.
No actions are planned yet tonight though.
Thanks Dustin.
