[Pacemaker] killing corosync leaves crmd, stonithd, lrmd, cib and attrd to hog up the cpu

[ihjaz Mohamed]

Hi All,

As part of some robustness test for my cluster, I tried killing the corosync process using kill -9 <pid>. After this I see that the pacemakerd service is stopped but the processes crmd, stonithd, lrmd, cib and attrd are still running and are hogging up the cpu.

Is there a way to cleanup these processes ? OR Do I need to kill them one by one before respawning the corosync?
