pNFS setup

[sheng qiu]

Hi,

does anyone can share your experience on setting up the pNFS of file
layout or block layout?
the wiki instruction :
http://wiki.linux-nfs.org/wiki/index.php/PNFS_Setup_Instructions does
not work for me on step

echo "/dev/sdc:192.168.0.1,192.168.0.2" >/proc/fs/nfsd/pnfs_dlm_device

since i do not have that directory entry after install the pNFS kernel
version. my system is ubuntu 14.

this is my config file related with nfs part:

CONFIG_NETWORK_FILESYSTEMS=y
CONFIG_NFS_FS=m
CONFIG_NFS_V2=m
CONFIG_NFS_V3=m
CONFIG_NFS_V3_ACL=y
CONFIG_NFS_V4=m

Take note of "step 0" on that page.

Server-side pNFS patches have not been merged into mainline (yet!).
You'll need a specially patched kernel for that.
