Reinstalling FluidFS from the Internal Storage Device

Each NAS controller contains an internal storage device from which you can reinstall the FluidFS factory image. If you experience

general system instability or a failure to boot, you might have to reinstall the image on one or more NAS

controllers.

Prerequisites

• If the NAS controller is still an active member in the FluidFS cluster, you must rst detach it.

• Connect a monitor to a NAS controller’s VGA port and connect a keyboard to one of the NAS controller’s USB ports.

CAUTION: Only reinstall the FluidFS software under the direction of Dell Technical Support.

WARNING: Reinstalling the FluidFS software on all NAS controllers will revert your system to factory defaults. All data on

the

FluidFS cluster will be unrecoverable after performing the procedure.

Steps

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

NOTE: Power o only the NAS controller on which you are reinstalling the FluidFS software. Do not power o the

remaining NAS controllers. Powering o a NAS controller disconnects client connections while clients are being

transferred to other NAS controllers. Clients will then automatically reconnect to the FluidFS cluster.

2. Press and release the recessed power button at the back of the NAS controller to turn on the NAS controller.

3. When you see the F11 = BIOS Boot Manager prompt, press F11.

4. Select the boot device USB Flash Disk.

5. Select Reinstall Dell FluidFS

<FluidFS_release_to_install>

NOTE: Reinstall the NAS controller to FluidFS version 2.0 only if you are redeploying the NAS controller in a FluidFS

version 2.0 cluster.

6. Conrm the action by typing resetmysystem (version 3.0) or resetmysystem -v2 (version 2.0) and pressing Enter.

7. Once the reinstallation completes, the NAS controller will reboot into standby mode.

8. After reinstalling FluidFS, attach the NAS controller to a FluidFS cluster.
