Unexpected change in NFS behavior (positive!)

[jode]

Two possible explanations:
Server-side copying:

NFS Copy without Network Transfer?

I am wondering if how to copy a file from one directory to another on the same zfs pool without having it run through my command and control computer. Meaning computer A (main desktop) uses nfs to copy a file on computer B to another directory without having the files transferring through Computer A. Basically using explorer in windows or linux fi…

The other possible explanation is use of RDMA over infiniband which shouldn’t show as network traffic because it bypasses IP stack.

However, both shouldn’t happen without me doing anything.
