diagnose -n

(Maui Node Diagnostics)

Synopsis:

diagnose -n [ -t <PARTITION>] [ -v ] [<NODENAME>]

Overview:

The 'diagnose -n' command provides detailed information about the state of nodes Maui is currently tracking. This command also performs a large number of sanity and state checks. The node configuration and status information as well as the results of the various checks are presented by this command.

Flags:

-n	(nodes)	diagnose node information
-t <PARTITION>	(partition)	show only nodes contained in the specified partition
-v	(verbose)	do not truncate data fields

Output:

This command presents detailed node information in whitespace delineated fields.

A few upfront notes about this command. First, the output of this command is VERY long. You will need to have a wide window or will need to mentally 'unwrap' the output. Second, it is important to note that a number of fields will contains truncated outputs by default (ie, the 'Classes' column is truncated at 20 characters). You will need to use the '-v' flag to see the entire field content.
