Description of problem:

When an NFSv4.1 client is doing pnfs IO, it gets a layout with deviceid where data is located, then does GETDEVICEINFO where the server returns it a list of IPs over which the client can do trunking to the data server. However when MDS=DS, then client incorrectly throws away the first entry in the getdeviceinfo list and then doing IO over the other connections.

An upstream patch was submitted to fix it: "NFSv4.1: fix pnfs MDS=DS session trunking". Will update when I have a commit id.
