NFS Shared Resource Configuration

Configuration requirements for NFS shared resources on a CFS server are affected by the NFS version or

versions that must be supported. The following procedures step through the configuration issues that

must be taken into account.

For NFS version 3, the specified fsid is optional and can be any 32-bit number and must be unique

among all the exported file systems. For NFS version 4, the fsid for the root of the NFSv4 export tree

must be 0.

Add an NFSv3 Share Point

1. Add the nfs mount specification - edit the /etc/exports file:

The following is a sample entry, using a mount point with the name "CFS1" and specifying a "rw"

option for read/write access and a "root_squash" option to prevent root write access:

/mnt/share_name/toplevel *(rw,root_squash)

For greater security, specify which clients can access the exported share as shown in the

following example:

/mnt/share_name/toplevel 192.168.50.0/24(rw,root_squash)

2. Start NFS using the following command as root:

# service nfs start

# chkconfig nfs on

Remove an NFS Share Point

To remove an NFS mount resource, simply comment out or remove the entry from the /etc/exports

file.

NOTE: After every change to this file, the NFS Server must be restarted. Changes are not dynamically

picked up as they are for a CIFS shared resource.

Upgrading CFS

The DX6000G Cluster File Server can be upgraded from its previous versions 2.5 and 2.6.x with minimal

interruption. Administrators should plan for 15-20 minutes of downtime during the upgrade process.

1. Extract the latest version of the Dell-DX-CFS Software.zip as root.

# unzip Dell-DX-CFS Software.zip

2. In the extracted folder, copy the latest CFS SW to root
