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.
