SQL Server Big Data Cluster restart issue

Question

Hello,
we set up a SQL Server 2019 Big Data Cluster on Vanilla (upstream) Kubernetes with 4 Red Hat Linux servers(3 worker nodes).
Functionally everything seems to be working.
One issue we notice is when we restart the primary replica node, SQL Server instance doesn't restart on the primary replica node.

Any thoughts on how to debug the issue?

Thank you.

Check the Kubernetes events for the SQL Server pods. Run commands like kubectl get pods and kubectl describe pod <pod-name> to see if there are any issues reported during the startup process.
