mdiag -n

(Moab Node Diagnostics)

Synopsis

mdiag -n [-t partitionid] [-A creds] [-v] [--format=xml] [nodeid]

Overview

The mdiag -n command provides detailed information about the state of nodes Moab 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.

Arguments

Flag	Argument	Description
[-A]	{user\|group\|account\|qos\|class\|job}:<OBJECTID>	report if each node is accessible by requested job or credential
[-t]	<partitionid>	report only nodes from specified partition
[-v]	-	show verbose output (do not truncate columns and add columns for additional node attributes)

Output

This command presents detailed node information in whitespace delineated fields.

The output of this command can be extensive and the values for a number of fields may be truncated. If truncated, the '-v flag can be used to display full field content.
