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:

Show help options
Show all help options
Show output help
Show required arguments
Show command options (mutually exclusive)
Show additional options

Output Options:

Specify output format as one of: text (default), xml
Specify file name for output (or "-" for stdout)

Required Arguments:

The attribute's name
Operate on all attributes matching this pattern (with -B, -D, -U, or -Y)

Command:

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.
Update attribute's value and time to wait (dampening) in the attribute manager. If this changes the value or dampening, the attribute will also be written to the cluster configuration, so be aware that repeatedly changing the dampening reduces its effectiveness. Requires -d/--delay
Update attribute's dampening in the attribute manager. If this changes the dampening, the attribute will also be written to the cluster configuration, so be aware that repeatedly changing the dampening reduces its effectiveness. Requires -d/--delay
Query the attribute's value from the attribute manager. By default this will query the value of the attribute on the local node. Use -N/--node for the value on a given node, or -A/--all for the value on all nodes.
Unset attribute from the attribute manager. At the moment, there is no way to remove an attribute. This option will instead set its value to the empty string.
(Advanced) Force the attribute manager to resend all current values to the CIB

Additional Options:

The time to wait (dampening) in seconds for further changes before sending to the CIB
(Advanced) The attribute set in which to place the value
Use the named node for setting and querying the attribute (instead of the local one)
Show values of the attribute for all nodes (query only)
(Not yet implemented) Lifetime of the node attribute (silently ignored by cluster)
If this creates a new attribute, never write the attribute to CIB
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'.
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
Increase debug output (may be specified multiple times)
