I am new in cluster.

We are running SAP Application in HA Cluster (have 2 nodes in cluster) using pacemaker. Node1 if it runs as a master always restart for a few times. After we check pacemaker logs, we found resource IP float (Virtual IP) failed in node1. May I know What is the rootcause for this problem and how to mitigate this issue ??.

  • The logs should have more clues hinting to the root cause. The `crm_mon` output should show the failures with a timestamp. Check the logs around that time. – Dok Apr 19 '22 at 17:49
  • I already check the logs, but the clue from the logs only this : ```2022-04-29T20:43:18.863881+07:00 erpswdeapapp1 pacemaker-execd[3016]: notice: rsc_ip_float_monitor_10000[9741] error output [ /usr/lib/ocf/resource.d/heartbeat/IPaddr2: fork: retry: Resource temporarily unavailable ]```. Why resource temporarily unavailable ??, do you have any experience about this ??. – M. Fachrizal Utama Apr 30 '22 at 09:51
