--- Comment #5 from Konstantin Belousov <k...@freebsd.org> ---
First, switch to 12.2. There were fixes for some NFS client issues that might
be
relevant (could be not).
I am sure that NFS client is not VNET-aware, i.e. it does not switch context
to the proper VNET as needed. Esp. when offloading async io to nfsiod daemons.
In other words, I do not expect the scenario 3 to work.
For the second scenario, nullfs remount of NFS mount, VNET jail should be
irrelevant. When the hang occurs, gather the procstat -kk -a output (on the
host). Also it might worth a try to '-o nocache' for nullfs mounts, I remember
there were some problems with nullfs+nfs+caching.
