To setup something like Oracle RAC or Linux HA or Sun Cluster, we need storage that is shared between 2 VMs or compute instances. Is this possible in openstack environment and if yes, then how, pls share.

Many Thanks

You can prefer Manila service. It provides you a durable file share for your application which requires shared storage.

This feature is currently unsupported in Cinder:
