[ClusterLabs] Resource failure-timeout does not reset when resource fails to connect to both nodes

[Sam Gardner]

I have a simple resource defined:

[root at ha-d1 ~]# pcs resource show dmz1
 Resource: dmz1 (class=ocf provider=internal type=ip-address)
  Attributes: address=172.16.10.192 monitor_link=true
  Meta Attrs: migration-threshold=3 failure-timeout=30s
  Operations: monitor interval=7s (dmz1-monitor-interval-7s)

This is a custom resource which provides an ethernet alias to one of the interfaces on our system.

I can unplug the cable on either node and failover occurs as expected, and 30s after re-plugging it I can repeat the exercise on the opposite node and failover will happen as expected.

However, if I unplug the cable from both nodes, the failcount goes up, and the 30s failure-timeout does not reset the failcounts, meaning that pacemaker never tries to start the failed resource again.

Full list of resources:

 Resource Group: network
     inif       (off::internal:ip.sh):       Started ha-d1.dev.com
     outif      (off::internal:ip.sh):       Started ha-d2.dev.com
     dmz1       (off::internal:ip.sh):       Stopped
 Master/Slave Set: DRBDMaster [DRBDSlave]
     Masters: [ ha-d1.dev.com ]
     Slaves: [ ha-d2.dev.com ]
 Resource Group: filesystem
     DRBDFS     (ocf::heartbeat:Filesystem):    Stopped
 Resource Group: application
     service_failover   (off::internal:service_failover):    Stopped

Failcounts for dmz1
 ha-d1.dev.com: 4
 ha-d2.dev.com: 4

Is there any way to automatically recover from this scenario, other than setting an obnoxiously high migration-threshold?
