Chapter 6. Configuring Cluster Resources
This chapter provides information on configuring resources in a cluster.
6.1. Resource Creation
Use the following command to create a cluster resource.
pcs resource create resource_id [standard:[provider:]]type [resource_options] [op operation_action operation_options [operation_action operation options]...] [meta meta_options...] [clone [clone_options] | master [master_options] | --group group_name [--before resource_id | --after resource_id] | [bundle bundle_id] [--disabled] [--wait[=n]]
When you specify the
--group option, the resource is added to the resource group named. If the group does not exist, this creates the group and adds this resource to the group. For information on resource groups, see Section 6.5, “Resource Groups”.
The
--before and --after options specify the position of the added resource relative to a resource that already exists in a resource group.
Specifying the
--disabled option indicates that the resource is not started automatically.
The following command creates a resource with the name
VirtualIP of standard ocf, provider heartbeat, and type IPaddr2. The floating address of this resource is 192.168.0.120, the system will check whether the resource is running every 30 seconds.
# pcs resource create VirtualIP ocf:heartbeat:IPaddr2 ip=192.168.0.120 cidr_netmask=24 op monitor interval=30s
Alternately, you can omit the standard and provider fields and use the following command. This will default to a standard of
ocf and a provider of heartbeat.
# pcs resource create VirtualIP IPaddr2 ip=192.168.0.120 cidr_netmask=24 op monitor interval=30s
Use the following command to delete a configured resource.
pcs resource delete resource_id
For example, the following command deletes an existing resource with a resource ID of
VirtualIP
# pcs resource delete VirtualIP- For information on the resource_id, standard, provider, and type fields of the
pcs resource createcommand, see Section 6.2, “Resource Properties”. - For information on defining resource parameters for individual resources, see Section 6.3, “Resource-Specific Parameters”.
- For information on defining resource meta options, which are used by the cluster to decide how a resource should behave, see Section 6.4, “Resource Meta Options”.
- For information on defining the operations to perform on a resource, see Section 6.6, “Resource Operations”.
- Specifying the
cloneoption creates a clone resource. Specifying themasteroption creates a master/slave resource. For information on resource clones and resources with multiple modes, see Chapter 9, Advanced Configuration.
