If I run sbd --help I see the option is there in SLES 11 SP4.  When I
put SBD_OPTS="-P" in both nodes (and restart openais in both) I get
these errors constantly (every 6 seconds or so):

Sep  7 22:28:41 sles11a kernel: [ 1434.159558] sbd[8628]: segfault at
ffffffffffffff44 ip 00007fc43cdff9bb sp 00007ffe5b429270 error 5 in
libcrmcommon.so.3.5.0[7fc43cdd0000+54000]

I tried using "-W -P" as well but still the same error.  If I remove the
SBD option, restart openais, the errors stop so no doubt whatsover that
the -P options is causing the issue.

This is on two virtual machines using the i6300esb module for watchdog
(qemu providing the virtual watchdog) running a simple two node cluster
(active/passive) as simple as it gets with two primitives:  Filesystem
(ext3) and sbd-stonith.

If anyone from SUSE here could recreate it that would be great.

Thanks,
