Problem:

While restarting the clusterware on one cluster node I got this error:

[root@fzppon06vs1n~]# crsctl start cluster

Analysis:

When checking the clusterware alertlog I can find the log stopped on this line:

2019-10-07 12:15:45.495 [EVMD(23031)]CRS-8500: Oracle Clusterware EVMD process is starting with operating system process ID 23031
I’ve checked the time between both cluster nodes and it was in sync.
Tried to stop the clusterware forcefully and start it up:

[root@fzppon06vs1n~]# crsctl stop crs -f

Looks there is a problem with stopping cssd and ctssd services as well.

Solution:

Restarted the node and the clusterware came up properly without errors:

[root@fzppon06vs1n ~]# sync;sync;sync; init 6

Analyzing such problem was challenging as there were no errors reported in the clusterware logs when the clusterware was hung during its start up. So far, restarting the RAC node is one of the silver bullet troubleshooting techniques for many of non-sense clusterware behaviors 😉
