Operation not permitted on `/var/lib/postgresql/pgdata` while using with Amazon EFS

[manoj016]

What did you do?

I am using timescaledb-multinode helm charts

I want to use Amazon EFS instead of local provisioner, so changed the storageClass inside the values.yaml file to efs-cs.

I am getting the below error in the initdb container for all the replicas.

install: cannot change owner and permissions of ‘/var/lib/postgresql/pgdata’: Operation not permitted

Did you expect to see some different?

The above is not working expected. The cluster should be up and running.
