Considerations for configuring High Availability on the Ozone Manager

There are various factors that you must consider when configuring High Availability (HA) for the Ozone Manager (OM).

  • OM HA is automatically enabled when you set up Ozone on a CDP cluster with at least three nodes as OM hosts.
  • You must define the OM on at least three nodes so that one OM node is the leader and the remaining nodes are the followers. The OM nodes automatically elect a leader.
    The following command lists the OM leader node and the follower nodes:
    ozone admin om getserviceroles -id=<ozone service id>
