MDS setup

MDS setup

I have an NFS server that I want to use as an MDS, so I'm going through
the pNFS setup instructions from the wiki --
http://www.linux-nfs.org/wiki/index.php/PNFS_Setup_Instructions

When I get to the step to tell the MDS the IP addresses of the DSs, I
get this response:

    bash: /proc/fs/nfsd/pnfs_dlm_device: Permission denied

Did I misconfigure something?

The system I'm working on is version 6.4 of the CentOS GNU/Linux
distribution.

I've built and installed the linux and nfs-utils from bhalevy's git
repositories. The linux version is 3.8.0-pnfs+, and the nfs-utils
version is 1.1.0.

It was a ridiculously stupid oversight: I hadn't built the pnfs support in
the kernel.

I got things squared away by running "make menuconfig" and enabling "NFSv4.1
server support for Parallel NFS (pNFS) (DEVELOPER ONLY)" under

File systems --->

  Network File Systems --->

    NFS server support

      NFS server support for NFS version 4 (EXPERIMENTAL)
