+# Managing the glusterd Service
+
+After installing GlusterFS and Glusterd2, you must start `glusterd2`
+service. The glusterd2 service serves as the Gluster elastic volume
+manager, overseeing glusterfs processes, and co-ordinating dynamic
+volume operations, such as adding and removing volumes across multiple
+storage servers non-disruptively.
+
+This section describes how to start the glusterd2 service in the
+following ways:
+
+**Note**: You must start glusterd2 on all GlusterFS servers.
+
+## Gluster user group
+
+On each server nodes, create "gluster" user group if not exists
+already using the following command.
+
+    # groupadd gluster
+
+Users from this group can run `glustercli` commands in GlusterFS
+servers.
+
+**Note**: Create "gluster" group before starting `glusterd2`
+
+## Starting and Stopping glusterd2 Manually
+
+This section describes how to start and stop glusterd2 manually
+
+To start glusterd2 manually, enter the following command:
+
+    # systemctl start glusterd2
+
+To stop glusterd2 manually, enter the following command:
+
+    # systemctl stop glusterd2
+
+## Starting glusterd Automatically
+
+This section describes how to configure the system to automatically
+start the glusterd2 service every time the system boots.
+
+    # systemctl enable glusterd2
+
+## Status
+
+Check the status of `glusterd2` using,
+
+    # systemctl status glusterd2
+
+To check the Cluster status, run the following command from one of the
+GlusterFS server.
+
+    # glustercli peer status
