Is the only approach to mmap the chunk on node B and then RDMA it to/from node A? I'm not going to watch a video, but with the pNFS code other nodes can access data on an XFS node directly using any SCSI transport. For RMDA that would be SRP or iSCSI/iSER. Note that I also have an unfinished draft to support NVMe, which has an RDMA transports as well and someone else could trivially reimplement that as well.
