Error: "mount.nfs: an incorrect mount option was specified" on Ubuntu 22.04 Jammy when nfs_udp is true

[richard-to]

Vagrant version

Vagrant 2.2.19

Host operating system

MacOS Monterey 12.3.1

Guest operating system

I'm using this box: ubuntu/jammy64

Vagrantfile

# -*- mode: ruby -*-
# vi: set ft=ruby :

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|

  config.vm.box = "ubuntu/jammy64"

  config.vm.network "private_network", ip: "172.31.1.10"
  config.ssh.forward_agent = true

  config.vm.synced_folder ".", "/vagrant", type: "nfs"

  config.vm.provider "virtualbox" do |vb, override|
    vb.memory = 3072

end

Always start with a minimal Vagrantfile and include only the relevant configuration

Debug output

The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

mount -o vers=3,udp 172.31.1.1:/Users/richard/Projects/my-repo /vagrant

Stdout from the command:



Stderr from the command:

mount.nfs: an incorrect mount option was specified

Expected behavior

The volume should have been mounted

Actual behavior

I got the error message: mount.nfs: an incorrect mount option was specified

Steps to reproduce

1. vagrant up

Notes

It works if I change the command to:

config.vm.synced_folder ".", "/vagrant", type: "nfs",  nfs_udp: false

So seems like the mount option changed for udp in Jammy?

This is expected in Ubuntu 22.04, take a look at the section "UDP disabled for NFS mounts" in the release notes:

[richard-to]

Ah thanks for pointing that out @lucaskanashiro. That's good to know. I also missed the Notes section in the vagrant docs about NFS v4: https://www.vagrantup.com/docs/synced-folders/nfs#other-notes
