The hosted-engine VM is currently protected for split brains with a volume lease but this prevents the user from taking snapshots or triggering a live storage migration of it. Hosted-engine VM is protected by a volume lease for historical reasons since it was the only available option when the project started. Now RHV offers also VM leases which provide many advantages over volume leases. We need to understand if we can apply this only to new deployments or if we can also safely reconfigure an existing hosted-engine VM from being protected by a volume lease to a VM lease.
We currently have no capacity for implementing this RFE.
