As I am exclusively using NFSv4 and seeing there is a new rc.conf setting nfsv4_server_only I enabled this setting on two machines in the context of upgrading 12.2 -> 13.0. Now when shutting down/rebooting, the following message appears in the log of both machines:
One of the machines however hangs for like 30-90 seconds where it is stopping the nfsd processes, before rc.shutdown terminates unexpectedly and then reboots. Given the above error message, I suspect it is trying to contact rpcbind (which is not running when nfsv4_server_only is enabled) and because this particular machine has TCP/UDP blackhole enabled, the request takes a long time before it times out.
Is this supposed to be happening with nfsv4_server_only enabled?
Code:
nfsd[1169]: rpcb_unset failed
