Understood, however the /etc/fstab entry on the client side is "user,rw,comment=systemd.mount" and the full set of mount options as shown by "mount" is: rw,nosuid,nodev,noexec,relatime,vers=3,rsize=32768,wsize=32768 namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys, mountaddr=xxx.xxx.xxx.xxx,mountvers=3,mountport=901 mountproto=udp,local_lock=none,addr=xxx.xxx.xxx.xxx,user which I interpret to mean no async, though maybe I'm mistaken. The server side is exporting async but AFAIK that isn't important here.
