Hi everyone. This is my first post to this list.
I think I found a bug in Bacula 2.2.8 after I spent a couple of days
struggling with two autochangers before regressing to 2.2.7, which
solved my problems.
Recently I rebuilt my director and main storage daemon box after a RAID
array died on the old one. I setup a new box (HP DL380 G4) with CentOS
5, x86_64, and 8G RAM. I also added a second Quantum PX502 autochanger.
I downloaded the 2.2.8 source RPM and built it using this commandline:
rpmbuild --rebuild --define nobuild_gconsole=1 --define build_mysql=1
--define build_centos5=1
The RPM built fine, and everything seemed to be working fine.. I used
the binaries to restore the old catalog from tape (some of you may have
seen me and my fun with MySQL index building in the IRC channel as
MapspaM).
Anyway, after getting things running again as they were with the old
configurations, I wanted to start using my new, second autochanger,
which is on /dev/sg0 and /dev/nst0 (the old one ended up on /dev/sg2
and /dev/nst1). Things got ugly at this point.
(In case you're wondering, my config files are at the bottom)
Any time I would try to run a backup job on the new Storage resource,
bacula-sd would disappear.
I tried a few more things including running seperate SD's and such.
Something about this new storage resource (In the attached configs as
LTO3-2) was broken.
I finally ran a seperate bacula-sd with
bacula-sd -f -d99 -c /etc/bacula/bacula-sd2.conf -u bacula -g bacula
And ran my backup job against it, which caused this output:
19-Feb 16:33 snap2-sd: ABORTING due to ERROR in dev.c:724
dev.c:723 Bad call to rewind. Device "PX502-2-Drive-1" (/dev/nst0) not open
Kaboom! bacula-sd, snap2-sd got signal 11 - Segmentation violation. Attempting
traceback.
The traceback failed due to "Permission Denied". I'm sorry but I
accidentally let the other debug messages scroll off my terminal, though
they looked normal. I can re-run the test after my backups for this week
finish if the debug output before/after that would be helpful. The
problems are very reproduceable, so it won't be hard.
Here are the configs. A few notes:
* I removed all the clients and jobs that didn't cause issues from the
configs.
* The segfault happened whether I was running with a seperate bacula-sd
or not, so bacula-sd.conf, and bacula-sd2.conf both had the problem. It
would seem though, that bacula-sd2.conf has something in it that
isolates this issue.
* When I was running bacula-sd2.conf, LTO3-2 had the port number changed
to 9104 to connect to the second sd, and the PX502-2 and its associated
resources were commented out of bacula-sd.conf.
* Of course, this could be the result of something in my catalog too,
I'm aware of that.
I'm hoping I can work with you all to figure out why 2.2.8 segfaults,
and 2.2.7 does not. I'm at your disposal and quite experienced with C/C
++ development, though not bacula's internals. Please just tell me what
other information and procedures would be helpful to you all to
debug/reproduce this.
