I have a simple resource defined:
[root@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?
