OCF_HEARTBEAT_LVM(7)						OCF resource agents					      OCF_HEARTBEAT_LVM(7)

NAME

       ocf_heartbeat_LVM - Controls the availability of an LVM Volume Group

SYNOPSIS

       LVM [start | stop | status | monitor | meta-data | validate-all]

DESCRIPTION

       Resource script for LVM. It manages an Linux Volume Manager volume (LVM) as an HA resource.

SUPPORTED PARAMETERS

       volgrpname
	   The name of volume group.

	   (required, string, no default)

       exclusive
	   If set, the volume group will be activated exclusively. This option works one of two ways. If the volume group has the cluster
	   attribute set, then the volume group will be activated exclusively using clvmd across the cluster. If the cluster attribute is not set,
	   the volume group will be activated exclusively through the use of the volume_list filter in lvm.conf. In the filter scenario, the LVM
	   agent verifies that pacemaker's configuration will result in the volume group only being active on a single node in the cluster and
	   that the local node's volume_list filter will prevent the volume group from activating outside of the resource agent. On activation
	   this agent claims the volume group through the use of a unique tag, and then overrides the volume_list field in a way that allows the
	   volume group to be activated only by the agent. To use exclusive activation without clvmd, the volume_list in lvm.conf must be
	   initialized. If volume groups exist locally that are not controlled by the cluster, such as the root volume group, make sure those
	   volume groups are listed in the volume_list so they will be allowed to activate on bootup.

	   (optional, boolean, default false)

       tag
	   If "exclusive" is set on a non clustered volume group, this overrides the tag to be used.

	   (optional, string, default "pacemaker")

       partial_activation
	   If set, the volume group will be activated even only partial of the physical volumes available. It helps to set to true, when you are
	   using mirroring logical volumes.

	   (optional, string, default "false")

SUPPORTED ACTIONS

       This resource agent supports the following actions (operations):

       start
	   Starts the resource. Suggested minimum timeout: 30.

       stop
	   Stops the resource. Suggested minimum timeout: 30.

       status
	   Performs a status check. Suggested minimum timeout: 30.

       monitor
	   Performs a detailed status check. Suggested minimum timeout: 30. Suggested interval: 10.

       methods
	   Suggested minimum timeout: 5.

       meta-data
	   Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5.

       validate-all
	   Performs a validation of the resource configuration. Suggested minimum timeout: 5.

EXAMPLE

       The following is an example configuration for a LVM resource using the crm(8) shell:

	   primitive p_LVM ocf:heartbeat:LVM 
	     params 
	       volgrpname=string 
	     op monitor depth="0" timeout="30" interval="10"
