crm_resource: Part of the Pacemaker cluster resource manager

NAME

Pacemaker - Part of the Pacemaker cluster resource manager

SYNOPSIS

crm_resource (query|command) [options]

DESCRIPTION

crm_resource - Perform tasks related to cluster resources. 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 cluster resources
-l, --list-raw
List the IDs of all instantiated 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)
-j, --pending
Display pending state if 'record-pending' is enabled
--list-standards
List supported standards
--list-ocf-providers
List all available OCF providers
--list-agents=value
List all agents available for the named standard and/or provider.
--list-ocf-alternatives=value
List all available providers for the named OCF agent
--show-metadata=value
Show the metadata for the named class:provider:agent
-q, --query-xml
Query the definition of a resource (template expanded)
-w, --query-xml-raw
Query the definition of a resource (raw xml)
-W, --locate
Display the current location(s) of a resource
-A, --stack
Display the prerequisites and dependents of a resource
-a, --constraints
Display the (co)location constraints that apply to a resource

Commands:

-C, --cleanup
Delete the resource history and re-check the current state. Optional: --resource
-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

Resource location:

-M, --move
Move a resource from its current location to the named destination. Requires: --host. Optional: --lifetime, --master
NOTE: This may prevent the resource from running on the previous location node until the implicit constraints expire or are removed with --unban
-B, --ban
Prevent the named resource from running on the named --host. Requires: --resource. Optional: --host, --lifetime, --master
If --host is not specified, it defaults to:
* the current location for primitives and groups, or
* the current location of the master for m/s resources with master-max=1
All other situations result in an error as there is no sane default.
NOTE: This will prevent the resource from running on this node until the constraint expires or is removed with --clear
-U, --clear
Remove all constraints created by the --ban and/or --move commands. Requires: --resource. Optional: --host, --master
If --host is not specified, all constraints created by --ban and --move will be removed for the named resource.
-u, --lifetime=value
Lifespan of constraints created by the --ban and --move commands
--master
Limit the scope of the --ban, --move and --clear commands to the Master role. For --ban and --move, the previous master can still remain active in the Slave role.

Advanced Commands:

-D, --delete
(Advanced) Delete a resource from the CIB
-F, --fail
(Advanced) Tell the cluster this resource has failed
--restart
(Advanced) Tell the cluster to restart this resource and anything that depends on it
--wait
(Advanced) Wait until the cluster settles into a stable state
--force-demote
(Advanced) Bypass the cluster and demote a resource on the local node. Additional detail with -V
--force-stop
(Advanced) Bypass the cluster and stop a resource on the local node. Additional detail with -V
--force-start
(Advanced) Bypass the cluster and start a resource on the local node. Additional detail with -V
--force-promote
(Advanced) Bypass the cluster and promote a resource on the local node. Additional detail with -V
--force-check
(Advanced) Bypass the cluster and check the state of a resource on the local node. Additional detail with -V

Additional Options:

-N, --node=value
Host uname
--recursive
Follow colocation chains when using --set-parameter
-t, --resource-type=value
Resource type (primitive, clone, group, ...)
-v, --parameter-value=value
Value to use with -p or -S
-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
-T, --timeout=value
(Advanced) Abort if command does not finish in this time (with --restart or --wait)
-f, --force

EXAMPLES

List the configured resources:
# crm_resource --list

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

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 '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
