Abstract
A storage cluster includes a group of data nodes having concurrent access to a shared filesystem. The shared filesystem is assigned to a first TLU of a first storage group. Other filesystems of the data nodes associated with the shared filesystem, such as snapshot copies of the shared filesystems and the root/configuration filesystems of the data nodes are assigned to TLUs of a second set of storage groups. The first storage group and the second set of storage groups are all associated with a Remote Data Replication (RDR) group for the storage cluster. An RDR facility is created between a storage array storing the shared filesystem and a backup storage array. The concurrently accessed shared filesystem and the filesystems of all data nodes accessing shared filesystem are replicated on the RDR facility to the backup storage array to enable failover of the storage cluster between sites.
