Reproducible: Always

Steps to Reproduce:
1. Start drbd and cman
2. make sure drbd is primary
3. Start /etc/init.d/clvmd start

Actual Results:  
The trace posted above in that process and in lvm.
vgscan seems to trigger the problem



I've already recompiled clvmd to be sure, same thing happens.
Works on 2.6.26.

[Comment 1 Mike Auty (RETIRED) 2008-10-18 22:34:19 UTC]

Hi, could you please specify exactly which version of clvmd you have installed?  You can find this by looking at the output of "emerge -pv clvm" (I assume you're actually refering to the package sys-fs/clvm?).

[Comment 2 nuitari 2008-10-19 00:00:48 UTC]

sys-fs/clvm-2.02.33

With the compile fix in http://bugs.gentoo.org/show_bug.cgi?id=231559

GCC is 4.3.2
I have sys-kernel/linux-headers-2.6.26 (which I guess might matter too)

[Comment 3 Robin Johnson 2009-12-26 01:38:46 UTC]

clvm is long merged into lvm.
