pbsnodes - pbs node manipulation
SYNOPSIS
pbsnodes [-{a|x}] [-q] [-s server] [node|:property]
pbsnodes -l [-q] [-s server] [state] [nodename|:property ...]
pbsnodes [-{c|d|o|r}] [-q] [-s server] [-n] [-N "note"] [node|:property]
DESCRIPTION
The pbsnodes command is used to mark nodes down, free or offline. It can also be used to list nodes and their state. Node information is
obtained by sending a request to the PBS job server. Sets of nodes can be operated on at once by specifying a node property prefixed by a
colon.
Nodes do not exist in a single state, but actually have a set of states. For example, a node can be simultaneously "busy" and "offline".
The "free" state is the absence of all other states and so is never combined with other states.
In order to execute pbsnodes with other than the -a or -l options, the user must have PBS Manager or Operator privilege.
OPTIONS -a All attributes of a node or all nodes are listed. This is the default if no flag is given.
-x Same as -a, but the output has an XML-like format.
-c Clear OFFLINE from listed nodes.
-d Print MOM diagnosis on the listed nodes. Not yet implemented. Use momctl instead.
-o Add the OFFLINE state. This is different from being marked DOWN. OFFLINE prevents new jobs from running on the specified
nodes. This gives the administrator a tool to hold a node out of service without changing anything else. The OFFLINE state
will never be set or cleared automatically by pbs_server; it is purely for the manager or operator.
-p Purge the node record from pbs_server. Not yet implemented.
-r Reset the listed nodes by clearing OFFLINE and adding DOWN state. pbs_server will ping the node and, if they communicate
correctly, free the node.
-l List node names and their state. If no state is specified, only nodes in the DOWN, OFFLINE, or UNKNOWN states are listed.
Specifying a state string acts as an output filter. Valid state strings are "free", "offline", "down", "reserve", "job-
exclusive", "job-sharing", "busy", "time-shared", or "state-unknown".
-N Specify a "note" attribute. This allows an administrator to add an arbitrary annotation to the listed nodes. To clear a
note, use -N "" or -N n.
-n Show the "note" attribute for nodes that are DOWN, OFFLINE, or UNKNOWN. This option requires -l.
-q Supress all error messages.
-s Specify the PBS server's hostname or IP address.

I have a cluster set up with a head node and compute nodes running TORQUE and MOAB. The distro is ROCKS 5.3. I've been having problems with the connectivity for the past couple weeks now. Every couple hours it seems like the network connectivity will just stop working: sometimes it'll start back up... (0 Replies)
Goal: for each hostname (mars, phobos, and deimos grab the value of state = in a variable so I work on it further.
I figured I'll need to use sed to find the target host name, then substitute the "linefeed and what I am assuming is a tab state =" to null and grab the state (in this case "free")... (3 Replies)
Hi,
I am new in system administration. I observe that some nodes in our cluster
are not considered as active by showq:
22 active jobs 217 of 257 processors in use by local jobs (84.44%)
15 of 17 nodes active (88.24%)
but then I try to log into... (1 Reply)
