This feature allows the admin to get the uuid of the node (on which the command is executed).
Usage: gluster system:: uuid get
This is required because we generate uuid of a node in a lazy manner. ie, we generate a uuid for the node, only on the first volume or peer operation, when the node requires an external identity.
Result (if any):
With this command, we can force the uuid generation, without a volume or peer operation performed. The uuid is persisted at /var/lib/glusterd/glusterd.info
