+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

+ longdesc: |
+ 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.
