Starting or stopping GPFS daemon on a node by using GUI

You can start and shut down the GPFS services on the nodes. You must be careful with shutting down the GPFS services on a node because it may not only affect the functioning of the node but also the entire cluster depending on the special roles of the nodes in the cluster.

Note: When shutting down the GPFS service on a node, consider the following consequences:
  • Unmounts all file systems and disrupt services on the node.
  • If the node is a quorum node, then the cluster may lose quorum. To maintain quorum, you need to be certain that the number of available quorum nodes is equal to the total number of quorum nodes divided by two plus one (total number of quorum nodes/2 + 1). Or you need to properly configure tiebreaker disks.

Perform the following steps to start and shut down GPFS daemon through IBM Storage Scale GUI:

  1. Go to Services > GPFS Daemon page in the IBM Storage Scale GUI.
  2. To start GPFS daemon on a node, select the node on which you need to start the GPFS daemon and click Start Up.
  3. To stop GPFS daemon on a node, select the node on which you need to shut down GPFS daemon and click Shut Down.
