By the way, what is the minimum Linux Kernel version required to connect to a NFS v4.1 server using pNFS? We only managed to get this working with kernel 4.0 (on the client) and it appears that this is the lowest kernel release that supports pNFS block clients (working with Linux pNFS recent block server). Could you please confirm this? Regards, Ben.
