Greetings all,
I'm getting a seg fault from the chg-scsi program when I try to do
'amcheck' and it's driving me somewhat crazy. (Apologies in advance for
the length of this email; I figured better too much info than not
enough).
Here's what happens:
Amanda Tape Server Host Check
-----------------------------
Holding disk /mnt/bfd/amanda: 107029540 KB disk space available, that's
plenty
amcheck-server: could not get changer info: <error> could not read result
from "/usr/amanda/libexec/chg-scsi" (got signal 11)
Amanda Backup Client Hosts Check
--------------------------------
Client check: 1 host checked in 0.017 seconds, 0 problems found
(brought to you by Amanda 2.4.2p2)
The chg-scsi.debug file contains:
chg-scsi: debug 1 pid 10411 ruid 526 euid 526 start time Fri Sep 7
11:16:55 2001
ARG [0] : /usr/amanda/libexec/chg-scsi
ARG [1] : -info
The amcheck.debug file contains:
amcheck: debug 1 pid 10408 ruid 526 euid 0 start time Fri Sep 7 11:16:55

could not get changer info: <error> could not read result from

And here's the backtrace, as much as I understand these things (which is
not a hell of a lot).

I've tried building amanda with shared libraries, with static, with both,
and the result is still the same. The hardware all works, as the other
backup package I'm looking at (NetVault) works without a hitch.
If anyone has any ideas, I'd really love to hear them.
Cheers,
Chris (the stressed!)
