Pacemaker − Part of the Pacemaker cluster resource manager
crm_resource (query|command) [options]
crm_resource − Perform tasks related to cluster resources. Allows resources to be queried (definition and location), modified, and moved around the cluster.

Call the validate−all action. There are two different things that can be validated. One method is to validate the resource given by the −r option. The other method is to validate a not−yet−existing resource. This method requires the −−class, −−agent, and −−provider arguments, plus at least one −−option argument.
If resource has any past failures, clear its history and fail count. Optionally filtered by −−resource, −−node, −−operation, and −−interval (otherwise all). −−operation and −−interval apply to fail counts, but entire history is always cleared, to allow current state to be rechecked.
Delete resource’s history (including failures) so its current state is rechecked. Optionally filtered by −−resource and −−node (otherwise all). Unless −−force is specified, resource’s group or clone (if any) will also be refreshed.
Set named parameter for resource (requires −v). Use instance attribute unless −−meta or −−utilization is specified.
Delete named parameter for resource. Use instance attribute unless −−meta or −−utilization is specified.
Create a constraint to move resource. If −−node is specified, the constraint will be to move to that node, otherwise it will be to ban the current node. Unless −−force is specified, this will return an error if the resource is already running on the specified node. If −−force is specified, this will always ban the current node. Optional: −−lifetime, −−master. NOTE: This may prevent the resource from running on its previous location until the implicit constraint expires or is removed with −−clear.
Create a constraint to keep resource off a node. Optional: −−node, −−lifetime, −−master. NOTE: This will prevent the resource from running on the affected node until the implicit constraint expires or is removed with −−clear. If −−node is not specified, it defaults to the node currently running the resource for primitives and groups, or the master for promotable clones with promoted−max=1 (all other situations result in an error as there is no sane default).
Remove all constraints created by the −−ban and/or −−move commands. Requires: −−resource. Optional: −−node, −−master, −−expired. If −−node is not specified, all constraints created by −−ban and −−move will be removed for the named resource. If −−node and −−force are specified, any constraint created by −−move will be cleared, even if it is not for the specified node. If −−expired is specified, only those constraints whose lifetimes have expired will be removed.
Modifies the −−clear argument to remove constraints with expired lifetimes.
Lifespan (as ISO 8601 duration) of created constraints (with −B, −M) (see https://en.wikipedia.org/wiki/ISO_8601#Durations)
Limit scope of command to the Master role (with −B, −M, −U). For −B and −M, the previous master may remain active in the Slave role.
(Advanced) Delete a resource from the CIB. Required: −t
(Advanced) Tell the cluster this resource has failed
(Advanced) Tell the cluster to restart this resource and anything that depends on it
(Advanced) Wait until the cluster settles into a stable state
(Advanced) Bypass the cluster and demote a resource on the local node. Unless −−force is specified, this will refuse to do so if the cluster believes the resource is a clone instance already running on the local node.
(Advanced) Bypass the cluster and stop a resource on the local node.
(Advanced) Bypass the cluster and start a resource on the local node. Unless −−force is specified, this will refuse to do so if the cluster believes the resource is a clone instance already running on the local node.
(Advanced) Bypass the cluster and promote a resource on the local node. Unless −−force is specified, this will refuse to do so if the cluster believes the resource is a clone instance already running on the local node.
(Advanced) Bypass the cluster and check the state of a resource on the local node.
The standard the resource agent confirms to (for example, ocf). Use with −−agent, −−provider, −−option, and −−validate.
The agent to use (for example, IPaddr). Use with −−class, −−provider, −−option, and −−validate.
The vendor that supplies the resource agent (for example, heartbeat). use with −−class, −−agent, −−option, and −−validate.
Specify a device configuration parameter as NAME=VALUE (may be specified multiple times). Use with −−validate and without the −r option.
Follow colocation chains when using −−set−parameter
Resource XML element (primitive, group, etc.) (with −D)
Value to use with −p
Use resource meta−attribute instead of instance attribute (with −p, −g, −d)
Use resource utilization attribute instead of instance attribute (with −p, −g, −d)
Operation to clear instead of all (with −C −r)
Interval of operation to clear (default 0) (with −C −r −n)
(Advanced) XML ID of attributes element to use (with −p, −d)
(Advanced) XML ID of nvpair element to use (with −p, −d)
(Advanced) Abort if command does not finish in this time (with −−restart, −−wait, −−force−*)
If making CIB changes, do so regardless of quorum. See help for individual commands for additional behavior.
List the available OCF agents:
# crm_resource −−list−agents ocf
List the available OCF agents from the linux−ha project:
# crm_resource −−list−agents ocf:heartbeat
Move ’myResource’ to a specific node:
# crm_resource −−resource myResource −−move −−node altNode
Allow (but not force) ’myResource’ to move back to its original location:
# crm_resource −−resource myResource −−clear
Stop ’myResource’ (and anything that depends on it):
# crm_resource −−resource myResource −−set−parameter target−role −−meta −−parameter−value Stopped
Tell the cluster not to manage ’myResource’:
The cluster will not attempt to start or stop the resource under any circumstances. Useful when performing maintenance tasks on a resource.
# crm_resource −−resource myResource −−set−parameter is−managed −−meta −−parameter−value false
Erase the operation history of ’myResource’ on ’aNode’:
The cluster will ’forget’ the existing resource state (including any errors) and attempt to recover the resource. Useful when a resource had failed permanently and has been repaired by an administrator.
# crm_resource −−resource myResource −−cleanup −−node aNode
