The node on which the  mmgetstate  command is run must have the GPFS mounted. The node  must also run remote shell commands on any other node in the GPFS/IBM Spectrum Scale  cluster without the use of a password and without producing any extraneous messages. Example 7-1 shows how to get status about the GPFS/IBM Spectrum Scale daemon on one  or more nodes. The  -a  argument shows the state of the GPFS/IBM Spectrum Scale daemon on all nodes in  the cluster. Permissions:  Retrieving the status for GPFS/IBM Spectrum Scale requires root user  permissions. The following GPFS/IBM Spectrum Scale states are recognized and shown by this command: If the GPFS/IBM Spectrum Scale state is not active, attempt to start GPFS/IBM Spectrum  Scale and check its status, as shown in Example 7-2. If the status is active, also check the GPFS/IBM Spectrum Scale mount status by running the  command that is shown in Example 7-3. The message confirms that the GPFS file system is mounted.
