Hi,
I am using Pacemaker-1.1.
- pacemaker f722cf1ff9 (2012 Oct10)
- corosync dc7002195a (2012 Oct11)
If monitor (_on-fail is stop_) of a master resource fails, the resource
repeats restart in other node.
[test case]
1. use StatefulRA which set on-fail="stop" of Master's monitor.
[configuration of master-slave resource]
ms msAP prmAP \
meta master-max="1" master-node-max="1" \
clone-max="2" clone-node-max="1"
primitive prmAP ocf:pacemaker:Stateful \
:
op monitor role="Master" interval="10s" timeout="20s" on-fail="stop" \
:
# crm_mon -rfA1

2 Nodes configured, unknown expected votes
4 Resources configured.
Online: [ vm5 vm6 ]
Full list of resources:
Master/Slave Set: msAP [prmAP]
Masters: [ vm5 ]
Slaves: [ vm6 ]
Clone Set: clnPingd [prmPingd]
Started: [ vm5 vm6 ]
Node Attributes:
* Node vm5:
+ default_ping_set : 100
+ master-prmAP : 10
* Node vm6:
+ default_ping_set : 100
+ master-prmAP : 5
Migration summary:
* Node vm5:
* Node vm6:
2. let the master resource on vm5 fail,
# echo a >> /var/run/Stateful-prmAP.state
then the master-slave resource repeats restart on vm6.
the state of the following (a)~(c) is repeated.
