master replica

1. The first instance of a specific directory in the namespace. Once copies of the directory have been made, it is possible to designate a different replica as the master if necessary, but only one master replica of a directory can exist at a time. CDS can create, update, and delete object entries and soft links in a master replica.

2. Security: An instance of a Security Server that accepts queries and updates to its associated registry database. The master replica dynamically propagates its updates to slave replicas. Each cell has only one master replica. See also slave replica.
