Primary pod is in pending state for a long duration

Primary pod and Operator pod have pod anti-affinity set.

To resolve the issue of long duration pending state of primary pod

Verify if Operator pod and Primary pod are scheduled to same node using the following commands:
kubectl get all -n <primary pod namespace> -o wide
kubectl get all -n <operator pod namespace> -o wide
If it is allocated to same node then create new node with same node selector given in CR for primary server.
Delete the Primary pod which is in pending state.
The newly created Primary pod must not be in pending state now.
