Pacemaker - Part of the Pacemaker cluster resource manager
crm_resource <query>|<command> [options]
crm_resource - perform tasks related to Pacemaker cluster
resources
- -L, --list
- List all cluster resources with status
- -l,
--list-raw
- List IDs of all instantiated resources (individual members rather than
groups etc.)
- -O,
--list-operations
- List active resource operations, optionally filtered by --resource
and/or --node
- -o,
--list-all-operations
- List all resource operations, optionally filtered by --resource
and/or --node
- --list-standards
- List supported standards
- --list-ocf-providers
- List all available OCF providers
- --list-agents=STD:PROV
- List all agents available for the named standard and/or provider
- --list-ocf-alternatives=AGENT
- List all available providers for the named OCF agent
- --show-metadata=SPEC
- Show the metadata for the named class:provider:agent
- -q,
--query-xml
- Show XML configuration of resource (after any template expansion)
- -w,
--query-xml-raw
- Show XML configuration of resource (before any template expansion)
- -g,
--get-parameter=PARAM
- Display named parameter for resource (use instance attribute unless
--meta or --utilization is specified)
- -W, --locate
- Show node(s) currently running resource
- -a,
--constraints
- Display the location and colocation constraints that apply to a resource,
and if --recursive is specified, to the resources directly or
indirectly involved in those colocations. If the named resource is part of
a group, or a clone or bundle instance, constraints for the collective
resource will be shown unless --force is given.
- -A, --stack
- Equivalent to --constraints --recursive
- -Y, --why
- Show why resources are not running, optionally filtered by
--resource and/or --node
- --validate=LEVEL
- Validate resource configuration by calling agent's validate-all action.
The configuration may be specified either by giving an existing resource
name with -r, or by specifying --class, --agent, and
--provider arguments, along with any number of --option
arguments. An optional LEVEL argument can be given to control the level of
checking performed.
- -C, --cleanup
- 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 clear, to allow current state to be rechecked. If the
named resource is part of a group, or one numbered instance of a clone or
bundled resource, the clean-up applies to the whole collective resource
unless --force is given.
- -R, --refresh
- Delete resource's history (including failures) so its current state is
rechecked. Optionally filtered by --resource and --node
(otherwise all). If the named resource is part of a group, or one numbered
instance of a clone or bundled resource, the refresh applies to the whole
collective resource unless --force is given.
- -p,
--set-parameter=PARAM
- Set named parameter for resource (requires -v). Use instance
attribute unless --meta or --utilization is specified.
- -d,
--delete-parameter=PARAM
- Delete named parameter for resource. Use instance attribute unless
--meta or --utilization is specified.
- -M, --move
- 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, --promoted. NOTE: This may prevent the
resource from running on its previous location until the implicit
constraint expires or is removed with --clear.
- -B, --ban
- Create a constraint to keep resource off a node. Optional: --node,
--lifetime, --promoted. 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 promoted instance of promotable clones with promoted-max=1
(all other situations result in an error as there is no sane
default).
- -U, --clear
- Remove all constraints created by the --ban and/or --move
commands. Requires: --resource. Optional: --node,
--promoted, --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.
- -e, --expired
- Modifies the --clear argument to remove constraints with expired
lifetimes.
- -u,
--lifetime=TIMESPEC
- Lifespan (as ISO 8601 duration) of created constraints (with -B,
-M) see https://en.wikipedia.org/wiki/ISO_8601#Durations)
- --promoted
- Limit scope of command to promoted role (with -B, -M,
-U). For -B and -M, previously promoted instances may
remain active in the unpromoted role.
- --master
- Deprecated: Use --promoted instead
- -D, --delete
- (Advanced) Delete a resource from the CIB. Required: -t
- -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
- --digests
- (Advanced) Show parameter hashes that Pacemaker uses to detect
configuration changes (only accurate if there is resource history on the
specified node). Required: --resource, --node. Optional: any
NAME=VALUE parameters will be used to override the configuration (to see
what the hash would be with those changes).
- --force-demote
- (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.
- --force-stop
- (Advanced) Bypass the cluster and stop a resource on the local node
- --force-start
- (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.
- --force-promote
- (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.
- --force-check=LEVEL
- (Advanced) Bypass the cluster and check the state of a resource on the
local node. An optional LEVEL argument can be given to control the level
of checking performed.
- -N,
--node=NAME
- Node name
- --recursive
- Follow colocation chains when using --set-parameter or
--constraints
- -t,
--resource-type=ELEMENT
- Resource XML element (primitive, group, etc.) (with -D)
- -v,
--parameter-value=PARAM
- Value to use with -p
- -m, --meta
- Use resource meta-attribute instead of instance attribute (with -p,
-g, -d)
- -z,
--utilization
- Use resource utilization attribute instead of instance attribute (with
-p, -g, -d)
- -n,
--operation=OPERATION
- Operation to clear instead of all (with -C -r)
- -I,
--interval=N
- Interval of operation to clear (default 0) (with -C -r
-n)
- --class=CLASS
- The standard the resource agent conforms to (for example, ocf). Use with
--agent, --provider, --option, and
--validate.
- --agent=AGENT
- The agent to use (for example, IPaddr). Use with --class,
--provider, --option, and --validate.
- --provider=PROVIDER
- The vendor that supplies the resource agent (for example, heartbeat). Use
with --class, --agent, --option, and
--validate.
- --option=PARAM
- Specify a device configuration parameter as NAME=VALUE (may be specified
multiple times). Use with --validate and without the -r
option.
- -s,
--set-name=ID
- (Advanced) XML ID of attributes element to use (with -p,
-d)
- -i,
--nvpair=ID
- (Advanced) XML ID of nvpair element to use (with -p,
-d)
- -T,
--timeout=N
- (Advanced) Abort if command does not finish in this time (with
--restart, --wait, --force-*)
- -f, --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 theresource; useful when a resource had failed
permanently and has been repaired by an administrator):
- # crm_resource --resource myResource --cleanup --node aNode
