How would that happen? The ID may not be random, but it is a long string
string of digits:
[root at n2 gpfs-git]# mmlscluster
GPFS cluster information
========================
GPFS cluster name: madagascar.frozen
GPFS cluster id: 7399668614468035547
ANYHOW, I think you can fix your problem, by using:
mmdelnode to retire nodes from the over-subscribed cluster.
mmcrcluster to create a new cluster
mmaddnode to join now unaffiliated nodes to the new cluster.
