[ClusterLabs] VIP monitoring failing with Timed Out error

[Pritam Kharat]

Hi Dejan

It is giving following info. Then I tried *crm resource restart sc_vip* too
but no trace found. Anything which I need to do more apart from this ?

root at sc-node-1:/var/lib/heartbeat# crm resource trace sc_vip stop
INFO: restart sc_vip to get the trace
