7.3. Enabling Kernel Modules

Execute the following commands to enable kernel modules:
  1. You must ensure that the dm_thin_pool and target_core_user modules are loaded in the Red Hat Gluster Storage nodes.
    # modprobe target_core_user
    # modprobe dm_thin_pool
    Execute the following command to verify if the modules are loaded:
    # lsmod | grep dm_thin_pool
    # lsmod | grep target_core_user

    Note

    To ensure these operations are persisted across reboots, create the following files and update each file with the content as mentioned:
    # cat /etc/modules-load.d/dm_thin_pool.conf
    dm_thin_pool
    # cat /etc/modules-load.d/target_core_user.conf
    target_core_user
  2. You must ensure that the dm_multipath module is loaded on all OpenShift Container Platform nodes.
    # modprobe dm_multipath
    Execute the following command to verify if the modules are loaded:
    # lsmod | grep dm_multipath

    Note

    To ensure these operations are persisted across reboots, create the following file and update it with the content as mentioned:
    # cat /etc/modules-load.d/dm_multipath.conf
    dm_multipath
