+shortdesc: Cluster-aware LVM (auto activation)
+longdesc: |
+  Configures a resource to manage the activation of a volume
+  group. Before adding this resource, you need to proceed as below
+  to create new VG and LVs. Refer to manpage lvmlockd(8) for more
+  detailed steps.
+
+  - create VG on shared devices:
+    vgcreate --shared <vgname> <devices>
+
+  - create an LV:
+    lvcreate -an -L <size> -n <lvname> <vgname>
+
+  For LVs in shared VG, there are two activation modes: "exclusive"
+  and "shared". With the "exclusive" mode, a LV activated on one
+  host cannot be activated on another, which is the default option.
+  With the "shared" mode, a LV can be activated concurrently on
+  multiple hosts, and cluster filesystem like OCFS2 can use it.
+
+  If the resource is created with activation_mode="shared", it will
+  be added to the cLVM group resource. The cLVM group resource is
+  assumed to be named g-clvm. This is the name of the resource created
+  by the clvm wizard.
+

+  - name: id
+    shortdesc: Volume group instance ID

+      How a VG/LV is activated in cluster, either "exclusive" (default) or "shared".
+      It depends on the filesystem you need to create on the LV to choose the
+      activation mode. For local filesystem like ext4, you need "exclusive" activation.
+      For cluster filesystem like OCFS2, you need "shared" activation.
