ok, I tried this.

(1) run the resource

Master/Slave Set: ms-sf
stateful-1:0 (ocf::heartbeat:Stateful):Master node-b
stateful-1:1 (ocf::heartbeat:Stateful):Started node-a


(2) break master resource

# rm -f /var/run/heartbeat/rsctmp/Stateful-stateful-1\:0.state

Master/Slave Set: ms-sf
stateful-1:0 (ocf::heartbeat:Stateful):Stopped
stateful-1:1 (ocf::heartbeat:Stateful):Master node-a

Failed actions:
stateful-1:0_demote_0 (node=node-b, call=7, rc=7): complete


(3) clear master resource

# crm_resource -C -r stateful-1:0 -H node-b

Master/Slave Set: ms-sf
stateful-1:0 (ocf::heartbeat:Stateful):Stopped
stateful-1:1 (ocf::heartbeat:Stateful):Master node-a


(4) get back the failcount to "0"

# crm_failcount -r stateful-1:0 -U node-b -D

Master/Slave Set: ms-sf
stateful-1:0 (ocf::heartbeat:Stateful):Master node-b
stateful-1:1 (ocf::heartbeat:Stateful):Stopped


node-b could be master again,
but stateful-1:1 on node-a stopped instead of being slave(status Started).

at this time, the failcount for stateful-1:1/node-a is counted.

# cibadmin -Q | grep fail-count
<nvpair
id="status-c53511b5-7568-426e-bbd5-f258e24aa9ac-fail-count-stateful-1:1"
name="fail-count-stateful-1:1" value="1"/>

Is it needed to be counted?

Thanks,
Junko
