I will be rebooting all the servers tonight starting around 11pm, should be concluded by midnight, to install a new kernel, 5.10.1.  Hopefully it will work and one boot will be enough.

     As with 5.9 which never really worked, there have been significant changes to NFS which we make heavy use of here.  If it works it will be a win because some of those changes will bring about better efficiency especially for sparse files which will help when moving virtual machines between physical hosts.  I’ve tested the NFS client and it seems to be working well but can’t really test servers adequately except with real traffic.
