nfs mount with nfs 3

  • 772

I am running CentOS 6.4 Kernel version 2.6.32-358.23.2.el6.x86_64 #1 SMP and have the following nfs info:

  • nfs-utils-lib-1.1.5-6.el6.x86_64
  • nfs4-acl-tools-0.3.3-6.el6.x86_64
  • nfs-utils-1.2.3-36.el6.x86_64

and am trying to mount an NFS volume with nfs3. I have the following line in my fstab:

172.16.11.87:/volume1/web /home/nas nfsver=3 rsize=8192,wsize=8192,timeo=14,intr(no_root_squach)

When I run nfsstat it still shows the client as nfs4

  1. You have misspelled nfsvers=3 and no_root_squash.

  2. nfsvers is an option. 

    <server>:</remote/export> </local/directory> <nfs-type> <options> 0 0

    It seems that you missed the nsf-type. Changing nfsmount.conf may solve the problem in a system that will never work with nfs4. I have faced the same problem and it was solved like this in your fstab

    172.16.11.87:/volume1/web /home/nas nfs nfsvers=3 0 0
    • 4

  3. So that people can get a real answer to the problem, this is how I solved it:

    in the /etc/nfsmount.conf:

    change Defaultvers=4 to Defaultvers=3

    That's it, it now shows up as 

    nfsstat
Client rpc stats:
calls      retrans    authrefrsh
6          0          6
