The Project

Mission Statement

• To openly design and develop a NFSv4.1 parallel NFS (pNFS) implementation for OpenSolaris
• To verify and provide feedback to the IETF NFSv4 working group about the NFSv4.1 specification
• To understand the impacts and requirements of NFSv4.1 pNFS for OpenSolaris

Mailing List

• Don't forget to sign up for the NFSv4.1 project mailing list.

Proposed Deliverables

• Look at the NFS version 4.1 pNFS: Project Logistics page for an outline of the deliverables.

Status

Current Information

• We will be testing the Solaris pNFS client and server at the next interoperability event, the May 2008 ConnectAthon hosted by Sun and NetApp in San Jose, CA.

Past Information

• The pNFS client prototype was taken to the NFSv4 Bakeathon held in Ann Arbor, MI, Sept. 11-15, 2006. The OpenSolaris pNFS client was able to successfully do parallel I/O against all of the files-based pNFS servers in attendance.

• The pNFS client and server was taken to both the June 2007 Bakeathon in Austin, Texas and the October 2007 Bakeathon in Ann Arbor, MI.

The Technology

What is NFSv4.1?

• NFSv4.1 is the first minor version of NFSv4. The major extensions included in NFSv4.1 are Sessions, Directory Delegations and parallel NFS.

What is pNFS?

• The pNFS protocol allows us to separate a NFS file system's data and metadata paths. With a separate data path we are free to lay file data out in interesting ways like striping it across multiple different file servers. For more information, see the NFSv4.1 specification.

Links

• Summary (including slides) of the September 2006 FROSUG Meeting where pNFS was presented.
• NFSv4.1 Specification – Draft 17

tdh - Followup om pNFS testing under VMWare

Mar 28, 1:03 PM

I got a pNFS community and client to run under VMWare on a XP box. Okay, so I made sure to make independent clones of the same machine as before. And this time I went from 512M to 1G of available ...

tdh - auth records will not load if no share enabled

Mar 20, 6:51 PM

If you fail to share a zfs pool on the mds, then nfs will not be enabled and therefore the mds auth records will not load. # mdsadm -o add -t auth -a ip=10.1.233.117 adding: IP Addr - 10.1.233.117 ...

In no particular order... Do a banner of mds , client , and ds (or ds1, ds2, etc) and place it in /etc/motd for the respective hosts. It will help you more than you think. Especially after a core ...
