[Pacemaker] stonithd segfault

[Pavel]

Hello everyone

Can anyone, please assist me with the following problem. In syslog I get 
the following messages:

kernel: stonithd[2029]: segfault at 0 ip 00000000004047ed sp 
00007fffe886c8c0 error 4 in stonithd[400000+17000]
pacemakerd[2025]: notice: pcmk_child_exit: Child process stonith-ng 
terminated with signal 11 (pid=2029, core=128)

Then pacemakerd tries to respawn stonith-ng, but it fails again and this 
goes infinitely.

I have found a very similar problem in the mailing list archives, but it 
was already fixed and was related to Heartbeat only, while I'm using 
Corosync.

What I have noticed is that this is somehow related to DRBD that I 
configure. With empty configuration (no RAs) or some other RAs (IPaddr2, 
...), stonithd is running without any problem.
At the same time, despite the issue, DRBD Master / Slave resource seems 
to work correctly.

Here is my configuration:

> node $id="1" fio-node1 \
>     attributes standby="off"
> node $id="2" fio-node2 \
>     attributes standby="off"
> rsc_template drbd-r ocf:linbit:drbd \
>     op start interval="0" timeout="240" \
>     op promote interval="0" timeout="90" \

>     op stop interval="0" timeout="100" \

>     cluster-infrastructure="corosync" \
>     stonith-enabled="false" \
>     last-lrm-refresh="1366018562"

and here is drbd.conf:

> include "drbd.d/global_common.conf";
> include "drbd.d/*.res";
>
> resource r1 {
>     device /dev/drbd1;
>     disk /dev/vg-bio/lv1;
>     meta-disk internal;
>     on fio-node1 {

>     }
>     on fio-node2 {
>     address 172.17.68.129:7789;
>     }
> }

You can download full configuration (cib, corosync.conf, drbd.conf, 
drbd.d/global-common.conf) here -

I'm using Pacemaker 1.1.9 with Corosync 2.3.0 and crmsh 1.2.5 all built 
from source on Ubuntu Server 12.10 x64.
Build options for the above are:
pacemaker: ./configure --with-corosync --with-cs-quorum --without-ais 
--without-heartbeat --without-cman --with-snmp
corosync: ./configure --disable-rdma --disable-testagents --disable-dbus 
--enable-snmp --enable-qdevices
crmsh: ./configure

Any help or guidance is highly appreciated. Thanks!
