[Pacemaker] Weired resource-stickiness behavior

Thanks, Andrew, I applied infinity resource stickiness. However, the sst
resource is still switched to the node which is online back from failure.
And I found sth in the log:

Jun 13 11:46:29 node3 pengine[27813]:  warning: unpack_rsc_op: Processing
failed op monitor for ip_ssn on node2: not running (7)
Jun 13 11:46:29 node3 pengine[27813]:    error: native_create_actions:
Resource fs_ssn (ocf::Filesystem) is active on 2 nodes attempting recovery
Jun 13 11:46:29 node3 pengine[27813]:  warning: native_create_actions: See
http://clusterlabs.org/wiki/FAQ#Resource_is_Too_Active for more information.

Is this log showing that pacemaker tries to restart all the resource when
the failed node is back again?
