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.

    (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")
