Deleting a Cluster Export Services node from an IBM Storage Scale cluster

Use this information to delete a Cluster Export Services (CES) node from an IBM Storage Scale cluster.

  1. On a node other than the one you want to delete from the cluster, issue the following command to suspend the node:
    # mmces node suspend –N <Node_to_Delete>
  2. On the node that you want to delete from the cluster, issue the following commands to stop the CES services:
    # mmces service stop nfs
    # mmces service stop smb
    # mmces service stop s3

    In this example, it is assumed that all three protocols are enabled on the node that you want to delete from the cluster.

  3. On a node other than the one you want to delete from the cluster, issue the following command to disable CES on the node:
    # mmchnode –N <Node_to_Delete> --ces-disable
  4. On a node other than the one you want to delete from the cluster, issue the following command to shut down GPFS on the node:
    # mmshutdown –N <Node_to_Delete>
  5. On a node other than the one you want to delete from the cluster, issue the following command to delete the node from the cluster:
    # mmdelnode –N <Node_to_Delete>
  6. If you disabled file audit logging in step 1, you can enable it by following the instructions in Enabling file audit logging on a file system.
