Setup NFSv2 on RHEL7.1

Environment

• Red Hat Enterprise Linux 7.1
• NFS Server

Issue

• Run NFS version 2 (NFSv2) on NFS server
• Is NFSv2 supported?

Resolution

RHEL 7.1 can also be used as a NFS server for NFSv2. It's not enabled by default, but enabling it is fairly straightforward:

1. Edit /etc/sysconfig/nfs, and change the RPCNFSDARGS to the following (uncommenting if necessary):

    RPCNFSDARGS="-V 2"
   

2. Restart the nfs-config.service.

    systemctl restart nfs-config.service
   

3. Restart the nfs-server.service.

    systemctl restart nfs-server.service
   

Root Cause

Beginning with Red Hat Enterprise Linux 7, NFS version 2 (NFSv2) is no longer supported and therefore disabled by default.

Diagnostic Steps

• Check to see if NFS version 2 (NFSv2) is enabled using rpcinfo:

    rpcinfo -l localhost 100003 2
  

  Or:

    rpcinfo -p | grep -w nfs
