This occurs because the Solaris 10 NFS client uses the NFSv4 protocol to

mount the le system, and the Linux NFS client does not support NFSv4.

The solution to this problem is to change the default NFS client proto-

col that the Solaris system will use to the NFSv3 protocol. To do this, edit

/etc/default/nfs and add the line NFS CLIENT VERSMAX=3 to instruct So-

laris to use the NFSv3 protocol until the Linux nfs server software is upgraded

to support NFSv4.

If for some reason you want the Solaris nfs server not to support NFSv4, you

can do this by modifying /etc/default/nfs to indicate NFS SERVER VERSMAX=3

The Solaris system will now only support up to version 3 of the NFS protocol.
