Symptoms

Upon checking the VSAN health check in Monitor > VSAN > Health area, the user may see that the check failed on 'Performance service', on 'Stats parent election'.
VSAN health check stats parent election

 

Cause

The health checker is not detecting the Parent elected host from the nodes.

 

Resolution

In some occurrences, the first step to resolve this issue is to turn off the Performance Service in VC and turn it back on.

Go into the Cluster > Configure > Health and Performance > Performance Services > Disable Performance Service, and re-enable

 

Retest.

 

If the error persists, run the following commands to refresh the vSAN information about all the Hosts in the Cluster. For the below steps:

  1. Temporarily disable the Performance Service in VC again.
  2. On the nodes, determine which node is the true vSAN parent node:
    esxcli vsan cluster get
  3. From the output of the above command on each host, find which host is elected as the vSAN parent node.
  4. Run the following commands. On each host in the cluster, from an SSH session run:
    /etc/init.d/vsanmgmtd restart
    /etc/init.d/vsanvpd restart

 

Note: As a precaution, restart the above services on the Parent node last, to make sure it refreshes based on all other nodes current states.

 

Run the following commands on the vCenter appliance using SSH (if Windows VC, use the Windows VC CLI equivalents):

  • On vCenter through an SSH session, restart VSAN Health:
service-control --stop vmware-vsan-health
service-control --start vmware-vsan-health

 

  • On vCenter through an SSH session, restart SPS service:
service-control --stop vmware-sps
service-control --start vmware-sps

 

Wait 5-10 minutes, re-enable Performance Service in VC, and retest.
