Dell FluidFS NAS Solutions Administrator's Guide

Access Using NFS

To mount an NFS export folder on a NAS volume, from a shell on a client system, use the su command to log in as root and run the following command:
mount <FluidFS_client_VIP>:/<volume_name>/<exported_folder> <local_folder>
However, older versions of UNIX/Linux do not use TCP by default. The following mount command specifies the correct arguments.

To mount an NFS export folder on a NAS volume, from a shell on a client system, use the su command to log in as root and run the following command:

mount -o hard,tcp,nfsvers=3,timeo=3,retrans=10,rsize=32768,wsize=32768 
                              <FluidFS_Client_VIP>:/<volume_name><exported_folder> <local_folder>
                              
                           

For backward compatibility with FluidFS version 1, an NFS export on the default NAS volume can also be mount by:

mount -o hard,tcp,nfsvers=3,timeo=3,retrans=10,rsize=32768,wsize=32768 
                              <FluidFS_Client_VIP>:/<volume_name><exported_folder> <local_folder>
                              
                           

To mount an NFS export folder on a NAS volume from MAC:

mount_nfs -T -3 -r 32768 -w 32768 -P <FluidFS_Client_VIP>:/<volume_name><exported_folder> <local_folder>
  • NOTE: The above parameters are recommended parameters. See the mount command manual page for more information and other options.

To allow a UDP or TCP connection, you can configure the firewall settings in two ways:

  • Adjust the firewall settings so that the source IP address comes from either of the two controllers and not the client VIP.
  • Open the port range for UDP to allow ports as follows:

    Service Name

    FluidFS Port

    portmap

    111

    Statd

    4000 through 4008

    Nfs

    2049 through 2057

    nlm (lock manager)

    4050 through 4058

    mount

    5001 through 5009

    quota

    5051 through 5059
