amrmtape Segmentation Fault

[steves]

I installed from Core 4 disks, 2.4.5. Everytime I try to remove the labels from a tape, I get this error:

/usr/sbin/amrmtape: line 146: 5954 Segmentation fault amadmin${SUF} ${Config} export >${TmpSrc}

Any ideas?

Thanks in advance.

please give more information. Is the Amanda configuration working?
What was the complete amrmtape command used?

Yes the configuration seems to be working and I am reusing tapes until I am comfortable with setup.
I am using: amrmtape DailySet1 DailySet101
It seems to be working, at least partly because, I can relabel tapes after it's run.
Just crashes.

I'll be happy to provide other information if you need it. Thanks for your quick response.

run "sh -x amrmtape DailySet1 DailySet101" and supply the output.

If it's ok, list the content amanda.conf.

Thanks!

Hi Steves,

Are you using 2.4.5p1? Is it possible to upgrade to 2.5.0p2? It is difficult
to debug the problem without knowing which source base you are using.

If you have gdb, can you get the stack trace from the core file? If there
is no core file, please set the following ulimits and re-run the amrmtape
command.

ulimit -c unlimited
ulimit -n unlimited
ulimit -u unlimited

Thanks,
Paddy

[steves]

Hi Paddy,

We tried setting ulimit, -c unlimited worked but the other two -n & -u did not. We also were not able to get core files enabled. I don't want to spend too much time on an older code base. It's probably best to upgrade.
So..we are working on an upgrade to 2.5.0p2. It's built and I'll be working on migrating the configuration again tomorrow. Thank you for your support.

Steve

[steves]

I have upgraded to 2.5.0p2 and the amrmtape problem has cleared.

I have a new configuration issue for the client on the tape server. I'll start a new thread for this. Thank you.

Steve
