# General Operations
## Display the configuration
crmsh # crm configure show xml
pcs # pcs cluster cib
crmsh can show a simplified (non-xml) syntax as well
crmsh # crm configure show
## Display the current status
crmsh # crm status
pcs # pcs status
also
# crm_mon -1
## Node standby
Put node in standby
crmsh # crm node standby pcmk-1
pcs # pcs cluster standby pcmk-1
Remove node from standby
crmsh # crm node online pcmk-1
pcs # pcs cluster unstandby pcmk-1
crm has the ability to set the status on reboot or forever.
pcs can apply the change to all the nodes.
## Set cluster property
crmsh # crm configure property stonith-enabled=false
pcs # pcs property set stonith-enabled=false
# Resource manipulation
## List Resource Agent (RA) classes
crmsh # crm ra classes
pcs # pcs resource standards
## List available RAs
crmsh # crm ra list ocf
crmsh # crm ra list lsb
crmsh # crm ra list service
crmsh # crm ra list stonith
pcs # pcs resource agents ocf
pcs # pcs resource agents lsb
pcs # pcs resource agents service
pcs # pcs resource agents stonith
pcs # pcs resource agents
You can also filter by provider
crmsh # crm ra list ocf pacemaker
pcs # pcs resource agents ocf:pacemaker
## List RA info
crmsh # crm ra meta IPaddr2
pcs # pcs resource agent IPaddr2
Use any RA name (like IPaddr2) from the list displayed with the previous command
You can also use the full class:provider:RA format if multiple RAs with the same name are available :
crmsh # crm ra meta ocf:heartbeat:IPaddr2
pcs # pcs resource describe ocf:heartbeat:IPaddr2
## Create a resource
crmsh # crm configure primitive ClusterIP ocf:heartbeat:IPaddr2 \
params ip=192.168.122.120 cidr_netmask=32 \
op monitor interval=30s
pcs # pcs resource create ClusterIP IPaddr2 ip=192.168.0.120 cidr_netmask=32
The standard and provider (`ocf:heartbeat`) are determined automatically since `IPaddr2` is unique.
The monitor operation is automatically created based on the agent's metadata.
## Display a resource
crmsh # crm configure show
pcs # pcs resource show
crmsh also displays fencing resources.
The result can be filtered by supplying a resource name (IE `ClusterIP`):
crmsh # crm configure show ClusterIP
pcs # pcs resource show ClusterIP
crmsh also displays fencing resources.
## Display fencing resources
crmsh # crm resource show
pcs # pcs stonith show
pcs treats STONITH devices separately.
## Display Stonith RA info
crmsh # crm ra meta stonith:fence_ipmilan
pcs # pcs stonith describe fence_ipmilan
## Start a resource
crmsh # crm resource start ClusterIP
pcs # pcs resource enable ClusterIP
## Stop a resource
crmsh # crm resource stop ClusterIP
pcs # pcs resource disable ClusterIP
## Remove a resource
crmsh # crm configure delete ClusterIP
pcs # pcs resource delete ClusterIP
## Modify a resource
crmsh # crm resource param ClusterIP set clusterip_hash=sourceip
pcs # pcs resource update ClusterIP clusterip_hash=sourceip
pcs can also delete parameters for a given resource:
crmsh #
pcs # pcs resource update ClusterIP ip=192.168.0.98 nic=
## List the current resource defaults
crmsh # crm configure show type:rsc_defaults
pcs # pcs resource rsc defaults
## Set resource defaults
crmsh # crm configure rsc_defaults resource-stickiness=100
pcs # pcs resource rsc defaults resource-stickiness=100
## List the current operation defaults
crmsh # crm configure show type:op_defaults
pcs # pcs resource op defaults
## Set operation defaults
crmsh # crm configure op_defaults timeout=240s
pcs # pcs resource op defaults timeout=240s
## Set Colocation
crmsh # crm configure colocation website-with-ip INFINITY: WebSite ClusterIP
pcs # pcs constraint colocation add ClusterIP with WebSite INFINITY
With roles
crmsh #
pcs # pcs constraint colocation add Started AnotherIP with Master WebSite INFINITY
## Set ordering
crmsh # crm configure order apache-after-ip mandatory: ClusterIP WebSite
pcs # pcs constraint order ClusterIP then WebSite
With roles:
crmsh #
pcs # pcs constraint order promote WebSite then start AnotherIP
## Set preferred location
crmsh # crm configure location prefer-pcmk-1 WebSite 50: pcmk-1
pcs # pcs constraint location WebSite prefers pcmk-1=50
With roles:
crmsh #
pcs # pcs constraint location WebSite rule role=master 50 \#uname eq pcmk-1
## Move resources
crmsh # crm resource move WebSite pcmk-1
pcs # pcs resource move WebSite pcmk-1
crmsh # crm resource unmove WebSite
pcs # pcs resource unmove WebSite
Remember that moving a resource set a stickyness to -INF until unmoved
## Create a clone
crmsh # crm configure clone WebIP ClusterIP meta globally-unique="true" clone-max="2" clone-node-max="2"
pcs # pcs resource clone ClusterIP globally-unique=true clone-max=2 clone-node-max=2
## Create a master/slave clone
crmsh # crm configure ms WebDataClone WebData \
meta master-max=1 master-node-max=1 \
clone-max=2 clone-node-max=1 notify=true
pcs # resource master WebDataClone WebData \
master-max=1 master-node-max=1 clone-max=2 clone-node-max=1 \
notify=true
# Other operations
## Batch changes
crmsh # crm
crmsh # cib new drbd_cfg
crmsh # configure primitive WebData ocf:linbit:drbd params drbd_resource=wwwdata \
op monitor interval=60s
crmsh # configure ms WebDataClone WebData meta master-max=1 master-node-max=1 \
clone-max=2 clone-node-max=1 notify=true
crmsh # cib commit drbd_cfg
crmsh # quit
.
pcs # pcs cluster cib drbd_cfg
pcs # pcs -f drbd_cfg resource create WebData ocf:linbit:drbd drbd_resource=wwwdata \
op monitor interval=60s
pcs # pcs -f drbd_cfg resource master WebDataClone WebData master-max=1 master-node-max=1 \
clone-max=2 clone-node-max=1 notify=true
pcs # pcs cluster push cib drbd_cfg
