Main Functions

Replication Cluster

bsr defines a set of nodes for replication as a replication cluster, and basically supports a single primary mode that can act as a primary resource on only one node of the replication cluster member. Dual or multiple primary modes are not supported. The single primary mode, the Active-Passive model, is the standard approach to handling data storage media in a highly available cluster for failover.
