Subject: [NFS] Status of NFS/RDMA in mainline kernel?

Afternoon!

I haven't seen anything about NFS over RDMA lately. What's the current
status of this on both the server and client side?

Thanks!

Jeff

Sorry - I was thinking NFSv3 support, but I wouldn't mind learning
about NFSv4 as well.

The NFS/RDMA client will be part of 2.6.24. The code supports v2, v3,
and v4. The easiest way to obtain the code is to download the latest
2.6.24-rc from kernel.org. There are instructions describing how to
install and use the code at http://nfs-rdma.sf.net.

The server has been reviewed several times on this list recently. My
understanding is that it will be merged upstream in 2.6.25.

The client side support has already been merged into Linus' mainline
tree. It will be part of 2.6.24.

Server side support is lacking, so the client NFSv4 callback channels,
and NFSv3 sideband services like NLM and the MOUNT protocol will go over
standard tcp channels.

Cheers
Trond
