I had amanda up and
running only to discover that the machine acting as host didn't have enough HD
capacity to run Amanda smoothly. The project layed low for several weeks until I
got hold of a new and bigger machine.
Installed RedHat 9.0
on it and installed amanda and mtx
started configuring
everything as I remember doing it the last time, but now I've run into
problems (So I obviously couldn't remember it :-)
a mtx -f /dev/sg2
status gives me the following:
# mtx -f /dev/sg2
status

I can load and
unload tapes with mtx -f /dev/sg2 load/unload without
problems.

My changer.conf
placed at "/var/lib/amanda/BackUp/changer.conf" looks like
this:
firstslot=1
lastslot=19
cleanslot=18
AUTOCLEAN=0
autocleancount=99999

offlinestatus=1
OFFLINE_BEFORE_UNLOAD=0
All this taken from
the old machine which was working, now to the problems:
amcheck BackUp
gives:
Amanda Tape Server
Host Check
-----------------------------
Holding disk /backup: 163180648
KB disk space available, using 163149928 KB
amcheck-server: could not get
changer info: cannot determine first slot
#./chg-zd-mtx -info
displays:
<none> changerfile must be specified in
amanda.conf
amlabel
reports:
# amlabel BackUp

amlabel: could not load slot "current": cannot determine
first slot
Do anyone have a
clue where I have forgotten something?
