So the nfsvers setting doesn't seem to have an impact. I did verify at each pass that the 'nfsvers=' value was present and correct in the mount output. FYI: another user posted on the archlinux reddit with a similar issue, I suggested they try with a 5.12 kernel and that "solved" the issue for them as well. - mike On Thu, Aug 26, 2021 at 2:44 PM NeilBrown wrote: > > On Fri, 27 Aug 2021, Mike Javorski wrote: > > I finally had the chance to test with the offloading disabled on the > > server.
