having trouble setting up NFS server on centos 6.5

Question

Setup:

1. Provider: Linode

2. nfs server: a linode with centos 6.5

3. nfs client: a linode with centos 6.5

When I tried mounting

mount.nfs: access denied by server while mounting x.x.x.x:/shared

This is happening when I try to start nfs service both on client and server

[shortfellow@li829-73 ~]$ sudo service nfs restart
Shutting down NFS daemon:                                  [  OK  ]
Shutting down NFS mountd:                                  [  OK  ]
Shutting down RPC idmapd:                                  [  OK  ]
FATAL: Module nfsd not found.
FATAL: Error running install command for nfsd
Starting NFS services:                                     [  OK  ]
Starting NFS mountd:                                       [  OK  ]
Starting NFS daemon:                                       [  OK  ]
Starting RPC idmapd:                                       [  OK  ]

I do not understand the problem.

Answer 1

Please post your kernel version with the output of uname -a.

Being that this is a Linode instance, you're probably running a special kernel managed by the provider. The errors you're seeing indicate that NFS is not compiled into the kernel or the module not available.

Can you try:

# modinfo nfsd
# modprobe nfsd

Answer 2

# /etc/init.d/nfs start
FATAL: Module nfsd not found.
FATAL: Error running install command for nfsd

... It is actually harmless, you don't need to do anything. In case you want this to go away, uncomment (or add) the line

NFSD_MODULE="noload"

in /etc/sysconfig/nfs file.
