Restoring Local Groups
Restoring the local groups conguration provides an eective way to restore all local groups without having to manually recongure
them. This is useful in the following circumstances:
• After recovering a system
• When failing over to a replication target NAS volume
Local Groups Conguration Backups
Whenever a change in the local groups conguration is made, it is automatically saved in a format that allows you to restore it later.
The conguration is stored and encrypted in the .clusterConfig folder, which is located in the NAS volume's root folder. This
folder can be backed up, either individually, or with the NAS volume's user data, and later restored.
A local groups conguration backup can be made available to be restored using the following methods:
• The storage administrator can manually copy the .clusterConfig folder to a NAS volume in the system from its backup or
from another system. When using a backup from another system, the restore operation works only if the saved conguration
was taken from a system using the same FluidFS version.
• The storage administrator can copy the .clusterConfig folder to a NAS volume in the system from its backup or from
another system using an NDMP restore. When using a backup from another system, the restore operation works only if the
saved conguration was taken from a system using the same FluidFS version.
• The .clusterConfig folder is automatically copied to target NAS volumes during replication.
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 Dell Technical Support.
