Halting a set of nodes
Halts any number of nodes in the cluster. You can use the regular expressions previously described.
cmu> halt delay "message" cmu_nodes_regular_expression
where
delay
Indicates the time period after which the specified nodes are halted. It can be “now” or after
“1”, “5”, “10”, “15”, “30”, or “60” minutes.
message
A string that appears on every halted node.
