There were fixes for some NFS client issues that mi= ght 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 daem= ons. 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 reme= mber there were some problems with nullfs+nfs+caching. --=20 You are receiving this mail because: You are the assignee for the bug.=
