I've got a strange problem with LVM. My environment is four IBM x440 servers (2 CPU, 2G memory) interconnected with two fcs adapters and two switches to a FastT700 SAN storage array.

Due to circumstances we are trying to understand the FCS drivers did show our disk devices twice (once per adapter). This is a problem on our part, but vgscan should terminate with an error message instead of a segfault.

We've started out with 0.98beta2 (what came with out SuSE 7). The problem is the same with the latest tarball (1.0.7) from sistina.

#1 lore raw

Markus,

LVM 0.9 had the strncmp() call in line 148, 1.0.7 has it in line 155 which makes me believe that the output below belongs to a 0.9 run.

Please retest with 1.0.7 which avoids hitting the NULL pointer bug.

Regards,
Heinz -- The LVM Guy --

The other problem is that this is at a customer site on production machines. I can test the next time I'm there and got machine time to do some testing. This will happen as soon as the SAN support guys come back to me to solve the undelying problem (disks visible twice).

Heinz,

It looks like I'll be able to test stuff sometimes next week. Is these anything I can do to help pinpoint the problem ?

Heinz,

I'm pretty sure I've tested with 1.0.7. Look at the lines

Well, I derived the line numbers from the respective sources.

The other problem is that this is at a customer site on production machines. I can test the next time I'm there and got machine time to do some testing. This will happen as soon as the SAN support guys come back to me to solve the undelying problem (disks visible twice).

Ok.

Let's wait if it is reproducable with 1.0.7.

Can you make sure that you generate the software from scratch and fo a full install which makes sure that you really use the 1.0.7 lib as well (configure ; make ; make install) ?

Heinz,

Finally I've been able to test again. The problem, as you suspected is on my side. During my first test I didn't run 'make install'. The commands were the new ones, but the library was the old one. After installing properly the segfault went away.

Thanks for your support !

Markus
