Yeah, for some reason the failing system is looking for the rpc_pipefs
filesystem in a different mountpoint.

Double check that config in the nfsconf --dump output in both cases.

Title:
  /etc.nfs.conf fails for nfsv4 server / blkmapd dumps core

Status in nfs-utils package in Ubuntu:
  Incomplete

Bug description:
  When using the 22.04 /etc/nfs.conf an nfsv4 server fails to operate

  It kind of works but some clients fail and try nfsv3 ports

  symptoms:

  on boot:
  × nfs-blkmap.service - pNFS block layout mapping daemon
       Loaded: loaded (/lib/systemd/system/nfs-blkmap.service; enabled; vendor preset: enabled)
       Active: failed (Result: core-dump) since Sat 2022-06-25 07:14:34 PDT; 27min ago
  journalctl --catalog --pager-end --unit=nfs-blkmap.service
  Jun 25 07:14:34 c68z blkmapd[2386154]: open pipe file /run/rpc_pipefs/nfs/blocklayout failed: No such file or directory

  on systemctl restart nfs-server.service:
  ○ rpc-svcgssd.service - RPC security service for NFS server
       Loaded: loaded (/lib/systemd/system/rpc-svcgssd.service; static)
       Active: inactive (dead) since Fri 2022-06-24 19:07:31 PDT; 12h ago

  after boot it was:
  ● rpc-svcgssd.service - RPC security service for NFS server                                                                 
       Loaded: loaded (/lib/systemd/system/rpc-svcgssd.service; static)                                                       
       Active: active (running) since Sat 2022-06-25 08:27:27 PDT; 2min 7s ago                                                

  Some clients tries to access port 111 which is not used by nfs4 on the
  network
