Heads up message for PSARC 2007/347 NFS/RDMA -
Transport Version Update

If you do not use NFS over Infiniband, you can delete this message now.
--
This integration brings the NFS/RDMA Solaris Implementation up to date
with the latest IETF Drafts. Specifically, it removes support for the
initial NFS/RDMA implementation (version 0) and adds support for
rpcrdma [1] and nfsdirect [2] (version 1).
Please note that if a version 0 client contacts a version 1 server,
the client will revert to IP over IB without intervention from the
administrator. If a version 1 client contacts a version 0 server, the
client's mount will hang. The "proto=tcp" mount option can be used,
however, to allow the client to mount using IP over IB.
* Also note:
During our test cycle we hit this issue
6739454 system panics at sdpib:sdp_rts_announce
This issue is not related to this code integration, and this CR number
is provided for your information should you hit the panic.
Thanks,
The NFS Team.

You have brought joy to an old man's heart.
So why did it take so long? :-)
Thanks for a critical addition to Sun's InfiniBand-connected storage
portfolio!

I'm trying the new NFS/RDMA for the first time, and have trouble.
I'd appreciate your assistance. I'm running on amd64, nv_97.
My server exports "/export/home", "exportfs" shows:
- /export/home sec=sys,rw=wave128 "export"
I can do an nfs mount with no arguments, successfully:
mount -F nfs wave129:/export/home /mnt
cat /mnt/xxx # shows that it is mounted
I thought that NFS/RDMA was the default, so I was surprised to
NOT see an IB activity. So, then I try to force it to use IB:
umount /mnt
mount -F nfs -o proto=rdma wave129:/export/home /mnt
which gives me the error:
nfs mount: mount: /mnt: Invalid argument
Please advise.
-Bill Taylor

I think that "no activity" on an IP Infiniband interface means exactly that you *ARE* using RDMA transport. How did you check the activity? With netstat -i ?
