Shutting Down and Restarting NAS Controllers

In some cases, you must temporarily shut down a FluidFS cluster or reboot a NAS controller.

Shut Down the FluidFS Cluster

In some cases, you might need to temporarily shut down all NAS controllers in a FluidFS cluster. For example, you might need to do

this if you are moving the NAS hardware to a dierent location. When a FluidFS cluster is shut down, NAS volume data is no longer

available to clients and clients are disconnected.

Prerequisite

Schedule a maintenance window and inform clients that the resources hosted by the FluidFS cluster will be unavailable.

Steps

1. Change the FluidFS cluster operation mode to No Service.

2. Press and release the recessed power button at the back of each NAS controller to shut down the NAS controllers.

CAUTION: Follow the procedure exactly in the order that follows to prevent data inconsistency.

NOTE: Do not press and hold the power button down for several seconds. The NAS controllers will not shut down.
