Hi All, 

When a node joined while start of the resource takes time, start of the
resource is carried out twice. 

Step 1) Put sleep in start of the Dummy resource.(/usr/lib/ocf/resource.d/heartbeat/Dummy)
 (snip)
dummy_start() {
 sleep 60
 dummy_monitor
 if [ $? =  $OCF_SUCCESS ]; then
(snip)

Step 2) Start one node and send crm file. 
--------------------
### Cluster Option ###
property no-quorum-policy="ignore" \ 
stonith-enabled="false" \ crmd-transition-delay="2s" 

### Resource Defaults ###
rsc_defaults resource-stickiness="INFINITY" \ 
migration-threshold="1" 

### Group Configuration ###
group grpDummy \
 prmDummy1 \
 prmDummy2 

### Primitive Configuration ###
primitive prmDummy1 ocf:heartbeat:Dummy \
 op start interval="0s" timeout="120s" on-fail="restart" \
 op monitor interval="10s" timeout="60s" on-fail="restart" \
 op stop interval="0s" timeout="60s" on-fail="block" 
primitive prmDummy2 ocf:heartbeat:Dummy \
 op start interval="0s" timeout="120s" on-fail="restart"\
 op monitor interval="10s" timeout="60s" on-fail="restart" \
 op stop interval="0s" timeout="60s" on-fail="block" 

### Resource Location ###
location rsc_location-grpDummy-1 grpDummy \
 rule 200: #uname eq vm1 \
 rule 100: #uname eq vm2

-------------------- 
Step 3) When start of prmDummy1 was carried out, Start the second node. 
Start of prmDummy1 is carried out twice.

 [root at vm1 ~]# grep Initiating /var/log/ha-log
Jun  6 23:55:15 rh72-01 crmd[2921]:  notice: Initiating start operation prmDummy1_start_0 locally on vm1
Jun  6 23:56:17 rh72-01 crmd[2921]:  notice: Initiating start operation prmDummy1_start_0 locally on vm1 

While completion of start is unknown, it is not preferable for start to be carried out twice. 
When a node joined, it seems to be caused by the fact that information of thepractice of start which is not completed is deleted.


I registered these contents with Bugzilla.

I attach the file which I collected in crm_report to Bugzilla.
