crm_resource

NAME

Pacemaker - Part of the Pacemaker cluster resource manager

SYNOPSIS

crm_resource (query|command) [options]

DESCRIPTION

Allows resources to be queried (definition and location), modified, and moved around the cluster.

OPTIONS

-?, --help

This text

-$, --version

Version information

-V, --verbose

Increase debug output

-Q, --quiet

Print only the value on stdout

-r, --resource=value

Resource ID

Queries:

-L, --list

List all resources

-l, --list-raw

List the IDs of all instansiated resources (no groups/clones/...)

-O, --list-operations

List active resource operations. Optionally filtered by resource (-r) and/or node (-N)

-o, --list-all-operations

List all resource operations. Optionally filtered by resource (-r) and/or node (-N)

-q, --query-xml

Query the definition of a resource

-W, --locate

Display the current location(s) of a resource

-A, --stack

Display the pre-requisits and depandants of a resource

-a, --constraints

Display the (co)location constraints that apply to a resource

Commands:

-p, --set-parameter=value

Set the named parameter for a resource. See also -m, --meta

-g, --get-parameter=value

Display the named parameter for a resource. See also -m, --meta

-d, --delete-parameter=value

Delete the named parameter for a resource. See also -m, --meta

-M, --move

Move a resource from its current location, optionally specifying a destination (-N) and/or a period for which it should take effect (-u) If -N is not specified, the cluster will force the resource to move by creating a rule for the current location and a score of -INFINITY NOTE: This will prevent the resource from running on this node until the constraint is removed with -U

-U, --un-move

Remove all constraints created by a move command

Advanced Commands:

-D, --delete

Delete a resource from the CIB

-F, --fail

Tell the cluster this resource has failed

-R, --refresh

(Advanced) Refresh the CIB from the LRM

-C, --cleanup

(Advanced) Delete a resource from the LRM

-P, --reprobe

(Advanced) Re-check for resources started outside of the CRM

Additional Options:

-N, --node=value

Host uname

-t, --resource-type=value

Resource type (primitive, clone, group, ...)

-v, --parameter-value=value

Value to use with -p, -g or -d

-u, --lifetime=value

Lifespan of migration constraints

-m, --meta

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

-z, --utilization

Modify a resource's utilization attribute. For use with -p, -g, -d

-s, --set-name=value

(Advanced) ID of the instance_attributes object to change

-i, --nvpair=value

(Advanced) ID of the nvpair object to change/delete

-f, --force

EXAMPLES

List the configured resources:

# crm_resource --list

Display the current location of 'myResource':

# crm_resource --resource myResource --locate

Move 'myResource' to another machine:

# crm_resource --resource myResource --move

Move 'myResource' to a specific machine:

# crm_resource --resource myResource --move --node altNode

Allow (but not force) 'myResource' to move back to its original location:

# crm_resource --resource myResource --un-move

Tell the cluster that 'myResource' failed:

# crm_resource --resource myResource --fail

Stop a '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
