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)
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)
