Under some conditions, the disk type may change after recovery. Because of the datastore-specific way of determining provision type and a possible mismatch of the thin storage extent definition between the datastore and JetStream DR, a thin-provisioned disk may be restored as thick-provisioned. This corner case is only expected if a thin-provisioned disk is close to occupying all its allowed storage space. (DRBC-1267)
If a VM at the protected site has its “Replication cancelled” or contains non-protected (e.g., non-persistent) disks, the following restriction applies after a Planned Failover operation: (DRBC-6519)
When a protected domain with such VMs is running at the failover site after Planned Failover and when Continuous Failback is running at protected site, adding a new disk to any such VM may result in protection being cancelled for the new disk; if this occurs, it should be OK to restart protection for the VM at the failover site to re-synchronize the VM’s configuration at both sites.
