OneFS and nfs4

[Len Zaifman]

We would like to have :

NFS 4 ACLS
NFS 4 Mounting preferable to NFS 3
TCP only

I have seen references to NFS 4 in OneFS 6.5.x , but I have seen the
manual and cannot find NFS 4 refernces there.

1) Does Onefs 6.5.x (I think x is currently 3) have a fully
implemented and compliant NFS 4 implementation?
2) NFS failover works with NFS 3 and smartpools. Does NFS failover
still work with NFS 4 or does the TCP connection cause issues?

3) If a fully compliant NFS 4 is not available, are the above features
available?

Thanks.

Not on 6.5.x yet, but also very interested in this.  I'm using my Netapp specifically for NFSv4 because we're implementing ACLs for home directories.  I assume you're aware you can mount TCP for nfsv3 as well.

Oh also, the ACLs under NFSv3 on the isilon are very good. They do
server side ACLs that you can't do on the Netapp or other NFS
servers. chmod and ls have acl flags right on the isilon that are
interesting.

Hey Len,

Full disclosure here: I'm the NFS lead developer at Isilon. So that
means I can give you the answers you're looking for, but I might have
a bias towards Isilon. :)

1) Yes, we introduced our NFSv4 implementation in OneFS 6.5.0 and it
is fully compliant.
2) Unfortunately, NFSv4 puts a wrinkle in our current NFS failover
implementation, because NFSv4 includes much more state, such as open
files, byte range locks, share reservations and delegations. So we
don't yet support failover for NFSv4, but we're working towards that
goal.
3) Our NFSv4 implementation in 6.5.x does fully support NFSv4 ACLs.
They tie directly into our native Isilon ACL system, which supports
unix permissions and SMB/Windows ACLs. As Jerry mentioned, our ACL
system is pretty extensive and configurable.

Also you mentioned NFSv4 mounting - we've fully implemented the NFSv4
pseudofilesystem which allows you to mount "/" of the Isilon cluster
and browse to your exports.

Let me know if you have any more questions!

Thanks Nick. Judging by the other responses, this is not well known.

Do you have any updates to NFS 4.0 or 4.1 Paralell on upcoming OneFS updates? By the looks of the bugfixes you guys are working towards it.  We are staging a move to 7.0.1.3 and was excited to see a reply to the original poster.  I as well read about it in the bugfixes and manuals, but found no other documentation.
