Have a simple flex file server where the mds (NFSv4.1 or NFSv4.2) is also the ds (NFSv3). I.e., the metadata and the data file are the exact same file. This will allow testing of the flex file client. Simply add the "pnfs" export option to your export in /etc/exports and mount from a client that supports flex files.

Solaris NFS servers support an auxiliary NFSv3 ACL protocol that
|
|
never became an official part of the NFS version 3 protocol.
|
|
This protocol extension allows applications on NFS clients to

manipulate POSIX Access Control Lists on files residing on NFS
|

servers. NFS servers enforce POSIX ACLs on local files whether
|
|
this protocol is available or not.

|

clients which support the Solaris NFSv3 ACL protocol can then
|
|
access and modify ACLs on your NFS server.

To store ACLs on your NFS server, you also need to enable ACL-
