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 first 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 technical support.
  • 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 off only the NAS controller on which you are reinstalling the FluidFS software. Do not power off the remaining NAS controllers. Powering off 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. To turn on the NAS controller, press and release the recessed power button at the back of 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>.
  6. Confirm the action by typing resetmysystem 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.
