Manually Migrate Clients to Another NAS Controller
You can manually migrate clients between NAS controllers if, for example, the network load on the NAS controllers is not balanced.
Migrating a client to another NAS controller disconnects the client’s connection. Clients will then automatically reconnect to the NAS
controller to which they were migrated.
1 In the Storage view, select a FluidFS cluster.
2 Click the File System tab.
3 In the File System view, select Cluster Connectivity.
4 In the Filters panel, select a client and then click Move. The Move Client to NAS Controller dialog box opens.
5 From the Move Client to drop-down list, select the NAS controller to which to migrate the client.
6 Click OK.
Fail Back Clients to Their Assigned NAS Controller
You must fail back client connections to their original NAS controller when a NAS controller that was down becomes available. Failing back
client connections disconnects only the client connections that failed over due to the original NAS controller failure. Those clients will then
automatically reconnect to the assigned NAS controller.
1 In the Storage view, select a FluidFS cluster.
2 Click the File System tab.
3 In the File System view, select Cluster Connectivity.
4 In the Filters panel, click Failback. The Failback Clients dialog box opens.
5 Click OK.
Rebalance Client Connections Across NAS Controllers
Rebalancing client connections evenly distributes connections across all the available NAS controllers.
About this task
You must rebalance client connections in the following situations:
• After FluidFS cluster hardware changes (for example, adding a NAS appliance)
• When a NAS controller that was down becomes available
Rebalancing client connections disconnects all client connections. Clients will then automatically reconnect to the FluidFS cluster.
Steps
1 In the Storage view, select a FluidFS cluster.
2 Click the File System tab.
3 In the File System view, select Cluster Connectivity.
4 In the Filters panel, click Rebalance. The Rebalance Clients dialog box opens.
5 Click OK.
