Detaching The FluidFS NAS Cluster Solution Controller

In order to bring the cluster into the journalling mode you need to detach a controller while any hardware is being
replaced. This ensures that the system can be brought back to service with no downtime.
You may have to detach the controller under the following circumstances:
• A controller needs to be replaced with a new standby controller.
• The administrator wants to attach a working controller to another (more critical) cluster.

The Controllers Management page is displayed.
2. From the list of available controllers, select the appropriate controller and click Detach.
The selected controller is detached from the cluster, and powered off. This operation takes around 10 to 15
minutes.
