Stop each broker in the cluster, using the imqcmd command.
Restart the brokers that will remain in the cluster, using the imqbrokerd command’s -cluster option to specify only those remaining brokers.
For example, suppose you originally created a cluster consisting of brokers A, B, and C by starting each of the three with the command
imqbrokerd -cluster A,B, C |
To remove broker A from the cluster, restart brokers B and C with the command
imqbrokerd -cluster B,C |
