ocf_heartbeat_LVM - Controls the availability of an LVM Volume Group

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

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

volgrpname

The name of volume group.

(unique, 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 using a tag and the volume_list filter. When the tag option is in use, the volume_list in lvm.con must be initialized. This can be as simple as setting 'volume_list = []' depending on your setup.

(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 partially even with some physical volumes missing. It helps to set to true when using mirrored logical volumes.

(optional, string, default "false")

This resource agent supports the following actions (operations):

start

Starts the resource. Suggested minimum timeout: 30s.

stop

Stops the resource. Suggested minimum timeout: 30s.

status

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

monitor

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

methods

Suggested minimum timeout: 5s.

meta-data

Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5s.

validate-all

Performs a validation of the resource configuration. Suggested minimum timeout: 5s.

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="30s" interval="10s"

The following is an example configuration for a LVM resource using pcs(8)

pcs resource create p_LVM ocf:heartbeat:LVM \


  volgrpname=string \


  op monitor OCF_CHECK_LEVEL="0" timeout="30s" interval="10s"
