One of the primary benefits of using DFS Namespaces with PeerGFS is that Peer Management Center can control failover and failback by automatically disabling and enabling DFS namespace folder targets.
Peer Management Center and Agents are constantly looking for connectivity issues and other failures across linked file servers, the Peer Agents themselves, and entire sites. If Peer Management Center detects a failure, Peer Management Center can be set to automatically disable a linked DFS namespace folder target from a namespace folder. This will prevent end users from accessing the associated folder target. For details about enabling and disabling automatic failover to another folder target, see DFS-N Management in Collaboration, Replication, and Synchronization Job Preferences.
When Peer Management Center determines that a file server, Peer Agent, or entire site is back online, it automatically runs the following process to re-integrate that file server:
1.Kicks off a rescan to ensure the disconnected site or file server is brought back in sync with the others.
2.Re-enables the associated folder target once the re-scan is complete. Once this is done, DFS Namespaces begins to direct end users back to this file server.
For details about enabling and disabling automatic failback to another folder target, see DFS-N Management in Collaboration, Replication, and Synchronization Job Preferences. Automatic failback is enabled by default.
