[Pacemaker] should STONITH be a clone resource?

[Mia Lueng]

Hi All:
     I use a sbd device to be a STONITH device. Should I configure it
as a clone resource that running on all node?  I have seen a lot of
manuals to show it only be configured on a single node.   Here is my
configure:


# crm configure show
node hatest01
node hatest02
node hatest03
primitive sbd_stonith stonith:external/sbd \
	operations $id="sbd_stonith-operations" \
	op monitor interval="15" timeout="15" start-delay="15" \
	params sbd_device="/dev/vdb"
clone stonith_sbd sbd_stonith \
	meta clone-max="3" target-role="Started"
property $id="cib-bootstrap-options" \
	dc-version="1.1.2-2e096a41a5f9e184a1c1537c82c6da1093698eb5" \
	cluster-infrastructure="openais" \
	expected-quorum-votes="3" \
	no-quorum-policy="stop" \
	stonith-enabled="true"
op_defaults $id="op_defaults-options" \
	record-pending="false"


   Is it right?
