NAME

Pacemaker − Part of the Pacemaker cluster resource manager

SYNOPSIS

attrd_updater {-n <attribute> | -P <pattern>} <command> [options]

DESCRIPTION

query and update Pacemaker node attributes

OPTIONS

Help Options:
−h
, −−help

Show help options

−−help−all

Show all help options

−−help−output

Show output help

−−help−required

Show required arguments

−−help−command

Show command options (mutually exclusive)

−−help−additional

Show additional options

Output Options:
−−output−as
=FORMAT

Specify output format as one of: text (default), xml

−−output−to=DEST

Specify file name for output (or "−" for stdout)

−−text−fancy

Use more highly formatted output (requires −−output−as=text)

Required Arguments:
−n
, −−name=NAME

The attribute’s name

−P, −−pattern=PATTERN

Operate on all attributes matching this pattern (with −B, −D, −U, or −Y)

Command:
−U
, −−update=VALUE

Update attribute’s value. Required: −n/−−name or −P/−−pattern. Optional: −d/−−delay (if specified, the delay will be used if the attribute needs to be created, but ignored if the attribute already exists), −s/−−set, −p/−−private, −W/−−wait, −z/−−utilization.

−B, −−update−both=VALUE

Update attribute’s value and time to wait (dampening) in pacemaker−attrd. If this causes the value or dampening to change, the attribute will also be written to the cluster configuration, so be aware that repeatedly changing the dampening reduces its effectiveness. Requires −d/−−delay

−Y, −−update−delay

Update attribute’s dampening in pacemaker−attrd. If this causes the dampening to change, the attribute will also be written to the cluster configuration, so be aware that repeatedly changing the dampening reduces its effectiveness. Requires −d/−−delay

−Q, −−query

Query the attribute’s value from pacemaker−attrd

−D, −−delete

Unset attribute from pacemaker−attrd. At the moment, there is no way to remove an attribute. This option will instead set its value to the empty string.

−R, −−refresh

(Advanced) Force the pacemaker−attrd daemon to resend all current values to the CIB

Additional Options:
−d
, −−delay=SECONDS

The time to wait (dampening) in seconds for further changes before sending to the CIB

−s, −−set=SET

(Advanced) The attribute set in which to place the value

−N, −−node=NODE

Set the attribute for the named node (instead of the local one)

−A, −−all

Show values of the attribute for all nodes (query only)

−l, −−lifetime=SECTION

(Not yet implemented) Lifetime of the node attribute (silently ignored by cluster)

−p, −−private

If this creates a new attribute, never write the attribute to CIB

−W, −−wait=UNTIL

Wait for some event to occur before returning. Values are ’no’ (wait only for the attribute daemon to acknowledge the request), ’local’ (wait until the change has propagated to where a local query will return the request value, or the value set by a later request), or ’cluster’ (wait until the change has propagated to where a query anywhere on the cluster will return the requested value, or the value set by a later request). Default is ’no’.

−z, −−utilization

When creating a new attribute, create it as a node utilization attribute instead of an instance attribute. If the attribute already exists, its existing type (utilization vs. instance) will be used regardless. (with −B, −U, −Y)

Application Options:
−$, −−version

Display software version and exit

−V, −−verbose

Increase debug output (may be specified multiple times)
