ocf_heartbeat_LVM-activate — This agent activates/deactivates logical volumes.
LVM-activate [start | stop | monitor | meta-data | validate-all]
This agent manages LVM activation/deactivation work for a given volume group.
It supports the following modes, controlled by the vg_access_mode parameter:
* lvmlockd * system_id * clvmd * tagging
1. There are two possible configuration combinations: lvmlockd+LVM-activate and clvm+LVM-activate. However, it is not possible to use both at the same time!
2. Put all "lvmlockd"/"clvmd" volume groups into auto management by the agent if using the cluster to manage at least one of them. If you manage some manually, the stop action of the lvmlockd agent may fail and the node may get fenced, because some DLM lockspaces might be in use and cannot be closed automatically.
The volume group name.
(unique, required, string, no default)
If set, only the specified LV will be activated.
(optional, string, no default)
This option decides which solution will be used to protect the volume group in cluster environment. Optional solutions are: lvmlockd, clvmd, system_id and tagging.
(required, string, no default)
The activation mode decides the visibility of logical volumes in the cluster. There are two different modes: "shared" for cluster filesystem and "exclusive" for local filesystem. With "shared", an LV can be activated concurrently from multiple nodes. With "exclusive", an LV can be activated by one node at a time.
This option only has effect on "lvmlockd"/"clvmd" vg_access_mode. For "system_id" and "tagging", they always mean exclusive activation.
(optional, string, default "exclusive")
The tag used for tagging activation mode.
(optional, string, default "pacemaker")
This resource agent supports the following actions (operations):
Starts the resource. Suggested minimum timeout: 90s.
Stops the resource. Suggested minimum timeout: 90s.
Performs a detailed status check. Suggested minimum timeout: 90s. Suggested interval: 30s.
Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 10s.
Performs a validation of the resource configuration. Suggested minimum timeout: 20s.
Example CRM Shell
The following is an example configuration for a LVM-activate resource using the crm(8) shell:
primitive p_LVM-activate ocf:heartbeat:LVM-activate \ params \ vgname=string \ vg_access_mode=string \ op monitor timeout="90s" interval="30s" depth="0"
The following is an example configuration for a LVM-activate resource using pcs(8)
pcs resource create p_LVM-activate ocf:heartbeat:LVM-activate \ vgname=string \ vg_access_mode=string \ op monitor timeout="90s" interval="30s" depth="0"
