It looks like maybe the former is for NFSv3 and > the latter is for NFSv4? /sys/nfs* is the "old" (read: obsolete) NFS client and server. /sys/fs/nfs* is the "new" (default) NFS client and server. Both implementations do both NFSv2 and NFSv3; only the "new" implementation does NFSv4. Even if you are only using NFSv3, you want to be using the "new" implementation, and the "old" one should go away before the stable/11 branch happens. We're running a mix of 9.1 (with some earlier versions of Rick's DRC patches and FHA for NFSv3) and 9.2 (with the DRC patches) currently, and I'm looking through a bunch of changes to pull forward from stable/9. -GAWollman
