vtltape segfault with gitversion including commit from March 28

ap2010
Hi Mark,

I have updated the git version up until 30 march and now I get a segfault when running bacula, at the moment when it wants to read from the tape drive. This did not happen a few days ago.

Here is the vtlcmd 11 verbose output in messages:

And here is the error from bacula:

Hope this gives some clues?

And, before I forget, happy Easter ;-)

Happy Easter..

Any chance for a 'gdb /usr/bin/vtltape /path/to/core'
gdb> bt
gdb> quit

Also a copy of device.conf

I'll look at  this on Tuesday.

Cheers

Re: vtltape segfault with gitversion including commit from March 28

ap2010
Hi Mark,

I had loads of problems trying to locate the core dump file, which was nowhere to be found.

In the end, as a last resort I did a make clean on the git source, recompile and install, and did the same for the kernel module
(make clean; make; make install) and it works again nw.

I assume that the kernel module (which was installed) didn't match the latest vtltape binary for some reason.

So, note to myself, whenever weird things happen with mhvtl, recompile and install from scratch, including the kernel module.

Kind regards,

Albert

Happy Easter..

Any chance for a 'gdb /usr/bin/vtltape /path/to/core'
gdb> bt
gdb> quit

Also a copy of device.conf

I'll look at  this on Tuesday.

Hi Mark,

I have updated the git version up until 30 march and now I get a segfault when running bacula, at the moment when it wants to read from the tape drive. This did not happen a few days ago.

Here is the vtlcmd 11 verbose output in messages:

I can't see where any of the kernel module changes would have brought this unstuck..

However, the vtlcart.so & vtlscsi.so changes may have.

Re: core file.
Did you check the 'ulimit -c' value. Most Linux distributions default to '0' or no core file.

A 'ulimit -c unlimited' before starting any daemons (from the same shell) is normally required.

The main thing is that the problem has gone away :)

Hi Mark,

I checked the ulimit which was unlimited, just for fun I will try the explicit ulimit -c unlimited tonight to see if that works.
I assume the make process was muddled at some stage and did not recompile one of the dependencies, who knows.

Cheers,

Albert
