Restore Local Groups
Local groups can be restored by restoring the conguration stored on the most current NAS volume in the FluidFS cluster and restoring it
on the same system or on another system.
About this task
When you restore the local groups conguration, it overwrites and replaces the existing conguration. Clients that are currently connected
to the FluidFS cluster are disconnected. Clients will then automatically reconnect.
Steps
1 Ensure the.clusterConfig folder has been copied to the root folder of a NAS volume on the system on which to restore local
groups. One way to access the root folder of a NAS volume is to open Windows Explorer and in the address bar type: \
\client_vip_or_name\C$\nas_volume\
2 In the Storage view, select a FluidFS cluster.
3 Click the File System tab.
4 In the File System view, select a tenant and then select Client Accessibility.
5 Click the Local Users and Groups tab.
6 Click Restore.
The Restore Local Users from Replication Source dialog box opens.
7 From the Backup Source drop-down list, select the backup from which to restore local groups.
8 Click OK.
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 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 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 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 Conrm 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.
