A race condition that caused the sync not to succeed.
This is a known issue and currently there is no resolution.
To workaround this issue manually start "Workload Control Plane
" (wcp
) service from the vCenter Server Management Interface (VAMI) UI or by going to vCenter Server shell and running command:vmon-cli --start wcp
If the problem occurs when doing a patch of vCenter, please follow the same procedure as above once it fails, and then click the below option and select "Apply" (See screenshot):
vCenter patching activity should continue and finish successfully after doing this.
