Adding CES HDFS nodes into the centralized file system

  1. Ensure that the centralized file system is already installed, configured and active. For example, the IBM Storage Scale System.
  2. Create a CES shared root file system which will be used by CES installation.
    Note: The recommendation for CES shared root is a dedicated file system. A dedicated file system can be created with the mmcrfs command. The CES shared root must reside on GPFS and must be available when it is configured through mmchconfig.

    For more information, see the Setting up Cluster Export Services shared root file system topic in the IBM Storage Scale: Administration Guide.

  3. Add nodes designated for CES HDFS to the existing GPFS cluster.
    On a node that already belongs to the GPFS cluster issue the following command:
    mmaddnode -N c16f1n07.gpfs.net, c16f1n08.gpfs.net, c16f1n09.gpfs.net,
c16f1n10.gpfs.net, c16f1n11.gpfs.net, c16f1n12.gpfs.net

    Run mmlscluster to ensure that the nodes are added.

  4. After the CES HDFS nodes are added to the existing cluster follow the Enable and configure CES HDFS section to manually setup non-HA and HA HDFS Transparency cluster.
