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)
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)
