Synopsis

crm_resource  [-?|-V|-S] -L|-Q|-W|-D|-C|-P|-p [options]

Description

The crm_resource command performs various resource-related actions on the cluster. It can modify the definition of configured resources, start and stop resources, and delete and migrate resources between nodes.

--help, -?

Print the help message.

--verbose, -V

Turn on debug information.


Increase the level of verbosity by providing additional instances.

--quiet, -Q

Print only the value on stdout (for use with -W).

Commands

--list, -L

List all resources.

--query-xml, -x

Query a resource.

Requires: -r

--locate, -W

Locate a resource.

Requires: -r

--migrate, -M

Migrate a resource from its current location. Use -N to specify a destination.

If -N is not specified, the resource is forced to move by creating a rule for the current location and a score of -INFINITY.


This prevents the resource from running on this node until the constraint is removed with `-U`.

Requires: -r, Optional: -N, -f

--un-migrate, -U

Remove all constraints created by -M

Requires: -r

--delete, -D

Delete a resource from the CIB.

Requires: -r, -t

--cleanup, -C

Delete a resource from the LRM.

Requires: -r. Optional: -H

--reprobe, -P

Recheck for resources started outside the CRM.

Optional: -H

--refresh, -R

Refresh the CIB from the LRM.

Optional: -H

--set-parameter string, -p string

Set the named parameter for a resource.

Requires: -r, -v. Optional: -i, -s, and --meta

--get-parameter string, -g string

Get the named parameter for a resource.

Requires: -r. Optional: -i, -s, and --meta

--delete-parameter string, -d string

Delete the named parameter for a resource.

Requires: -r. Optional: -i, and --meta

--list-operations string , -O string

List the active resource operations. Optionally filtered by resource, node, or both. Optional: -N, -r

--list-all-operations string , -o string

List all resource operations. Optionally filtered by resource, node, or both. Optional: -N, -r

Options

--resource string, -r string

Specify the resource ID.

--resource-type string, -t string

Specify the resource type (primitive, clone, group, etc.).

--property-value string, -v string

Specify the property value.

--node string, -N string

Specify the hostname.

--meta

Modify a resource's configuration option rahter than one which is passed to the resouce agent script. For use with -p, -g and -d.

--lifetime string, -u string

Lifespan of migration constraints.

--force, -f

Force the resource to move by creating a rule for the current location and a score of -INFINITY

This should be used if the resource's stickiness and constraint scores total more than INFINITY (currently 100,000).


This prevents the resource from running on this node until the constraint is removed with `-U`.

-s string

(Advanced Use Only) Specify the ID of the instance_attributes object to change.

-i string

(Advanced Use Only) Specify the ID of the nvpair object to change or delete.

Examples

Listing all resources:

crm_resource -L

Checking where a resource is running (and if it is):

crm_resource -W -r my_first_ip

If the my_first_ip resource is running, the output of this command reveals the node on which it is running. If it is not running, the output shows this.

Start or stop a resource:

crm_resource -r my_first_ip -p target_role -v started

crm_resource -r my_first_ip -p target_role -v stopped

Query the definition of a resource:

crm_resource -Q -r my_first_ip

Migrate a resource away from its current location:

crm_resource -M -r my_first_ip

Migrate a resource to a specific location:

crm_resource -M -r my_first_ip -H c001n02

Allow a resource to return to its normal location:

crm_resource -U -r my_first_ip


The values of `resource_stickiness` and `default_resource_stickiness` may mean that it does not move back. In such cases, you should use `-M` to move it back before running this command.

Delete a resource from the CRM:

crm_resource -D -r my_first_ip -t primitive

Delete a resource group from the CRM:

crm_resource -D -r my_first_group -t group

Disable resource management for a resource in the CRM:

crm_resource -p is-managed -r my_first_ip -t primitive -v off

Enable resource management for a resource in the CRM:

crm_resource -p is-managed -r my_first_ip -t primitive -v on

Reset a failed resource after having been manually cleaned up:

crm_resource -C -H c001n02 -r my_first_ip

Recheck all nodes for resources started outside the CRM:

crm_resource -P

Recheck one node for resources started outside the CRM:

crm_resource -P -H c001n02
