Description

The CN's ReplicationManager should be called to check the availability of replicas on a regular basis. Replicas which have not been checked in 2 months or longer should have their checksum verified in order to ensure the copy remains as it was when it was correctly replicated.

As a part of this process, ReplicationManager will query the SOLR Indexer for a list of Identifiers corresponding to objects who have a Replica which has not been checked in 2 or more months. After a short list of Identifiers is received, the ReplicationManager will iterate through Identifiers and Replicas, binning them into tasks sorted by NodeReferences. An MNAuditTask will then be created and called for handling checksum verification for all objects that need to be checked on a Node.

If a Replica is found to have an incorrect checksum, the ReplicationStatus should be set to INVALIDATED, and ReplicationManager should coordinate replication to replace the invalid copy.
