+config OCFS2_FS_O2CB
+ tristate "O2CB Kernelspace Clustering"
+ depends on OCFS2_FS
+ default y
+ help
+ OCFS2 includes a simple kernelspace clustering package, the OCFS2
+ Cluster Base. It only requires a very small userspace component
+ to configure it. This comes with the standard ocfs2-tools package.
+ O2CB is limited to maintaining a cluster for OCFS2 file systems.
+ It cannot manage any other cluster applications.
+
+ It is always safe to say Y here, as the clustering method is
+ run-time selectable.
+
+config OCFS2_FS_USERSPACE_CLUSTER
+ tristate "OCFS2 Userspace Clustering"
+ depends on OCFS2_FS && DLM
+ default y
+ help
+ This option will allow OCFS2 to use userspace clustering services
+ in conjunction with the DLM in fs/dlm. If you are using a
+ userspace cluster manager, say Y here.
+
+ It is safe to say Y, as the clustering method is run-time
+ selectable.
