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" SEE ALSO

NAME
ocf_heartbeat_Raid1 - Manages a software RAID1 device on shared storage SYNOPSIS
Raid1 [start | stop | status | monitor | meta-data | validate-all] DESCRIPTION
Resource script for RAID1. It manages a software Raid1 device on a shared storage medium. SUPPORTED PARAMETERS
raidconf The RAID configuration file. e.g. /etc/raidtab or /etc/mdadm.conf. (required, string, no default) raiddev The block device to use. (required, string, no default) homehost The value for the homehost directive; this is an mdadm feature to protect RAIDs against being activated by accident. It is recommended to create RAIDs managed by the cluster with "homehost" set to a special value, so they are not accidentially auto-assembled by nodes not supposed to own them. (optional, string, no default) SUPPORTED ACTIONS
This resource agent supports the following actions (operations): start Starts the resource. Suggested minimum timeout: 20s. stop Stops the resource. Suggested minimum timeout: 20s. status Performs a status check. Suggested minimum timeout: 20s. Suggested interval: 10. monitor Performs a detailed status check. Suggested minimum timeout: 20s. Suggested interval: 10. validate-all Performs a validation of the resource configuration. Suggested minimum timeout: 5. meta-data Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5. EXAMPLE
