	I have a two node cluster based on cman+pacemaker running on ubuntu 12.04.

	Last weekend my active node was shutdown, even while I was stonith 
disabled. In my config I have:

primitive stonith_sbd stonith:external/sbd \
sbd_device="/dev/disk/by-id/wwn-0x60002ac0000000000000003500006f6d-part1" \
         meta target-role="Started"
property $id="cib-bootstrap-options" \
         dc-version="1.1.6-9971ebba4494012a93c03b40a2c58ec0eb60f50c" \
         cluster-infrastructure="cman" \
         expected-quorum-votes="2" \
         no-quorum-policy="ignore" \
         stonith-enabled="false" \
         last-lrm-refresh="1384411940" \
rsc_defaults $id="rsc-options" \

	But my node was halted after the message:

Nov 16 12:20:47 myotis51 sbd: [1377]: WARN: Latency: No liveness for 4 s 
exceeds threshold of 3 s (
healthy servants: 0)

	Should I stop sbd daemon even if I have stonith-enabled=false?
