These instructions explain how to start up a cluster that was previously shut down. 

To start up the cluster:

  1. If the cluster nodes are not running, start them.
  2. Change to the root user (or use sudo for the following commands).
  3. Start the ZooKeeper on nodes where it is installed. Example:

  4. On all nodes, start Warden. Example:

  5. Over a period of time (depending on the cluster size and other factors) the cluster comes up automatically. After the CLDB restarts, there is a 15-minute delay before replication resumes, in order to allow all nodes to register and heartbeat. This delay can be configured using the config save command to set the cldb.replication.manager.start.mins parameter.
