We need to check if having ES always in K8s is acceptable (performance tests) in order to use Ceph for shared storage (will be available in K8s cluster) or implement NFS, which seems to be ok just for backup purposes.

Changing this in the context of OpenSearch. We might need to verify again how todo this there.
