the NFS driver.</para>

<note>
<para>As of the Icehouse release, the NFS driver (and other
drivers based off it) will attempt to mount shares
using version 4.1 of the NFS protocol (including pNFS). If the
mount attempt is unsuccessful due to a lack of client or
server support, a subsequent mount attempt that requests the
default behavior of the <command>mount.nfs</command> command
will be performed. On most distributions, the default behavior
is to attempt mounting first with NFS v4.0, then silently fall
back to NFS v3.0 if necessary. If the
<option>nfs_mount_options</option> configuration option
contains a request for a specific version of NFS to be used,
or if specific options are specified in the shares
configuration file specified by the
<option>nfs_shares_config</option> configuration option, the
mount will be attempted as requested with no subsequent
attempts.</para>
