Verifying the Control Center configuration

This procedure verifies that the Control Center configuration is identical on both nodes.
  1. Log in to the primary node as root, or as a user with superuser privileges.
  2. In a separate window, log in to the secondary node as root, or as a user with superuser privileges.
  3. On both nodes, compute the checksum of the Control Center configuration file.
    cksum /etc/default/serviced
    • If the result is identical on both nodes, the configurations are identical. Do not perform the next step.
    • If the result is not identical on both nodes, there may be a difference in their configurations; proceed to the next step.
  4. Optional: On both nodes, display the customized variables, if necessary.
    grep -E '^[^#]*SERVICED' /etc/default/serviced | sort
    Example result:
    SERVICED_DM_THINPOOLDEV=/dev/mapper/serviced-serviced--pool
    SERVICED_DOCKER_REGISTRY=HA-Virtual-IP:5000
    SERVICED_ENDPOINT=HA-Virtual-IP:4979
    SERVICED_FS_TYPE=devicemapper
    SERVICED_LOG_ADDRESS=HA-Virtual-IP:5042
    SERVICED_LOGSTASH_ES=HA-Virtual-IP:9100
    SERVICED_MASTER=1
    SERVICED_OUTBOUND_IP=HA-Virtual-IP
    SERVICED_STATS_PORT=HA-Virtual-IP:8443
    SERVICED_ZK=HA-Virtual-IP:2181
