+             Specifies the path to a DIRECTORY containing files that
+             describe how to monitor the responsiveness of NFS RPC
+             services.  See the README file for this directory for an

+             CTDB_NFS_CHECKS_DIR can be used to point to different

+           <para>
+             One way of using this is to have it point to, say,
+             <filename>/usr/local/etc/ctdb/nfs-checks-enabled.d</filename>
+             and populate it with symbolic links to the desired check
+             files.  This avoids duplication and is upgrade-safe.
+           </para>
+           <para>
+             Default is
+             <filename>/usr/local/etc/ctdb/nfs-checks.d</filename>,
+             which contains NFS RPC checks suitable for Linux kernel
+             NFS.
