Vagrantfile

My Vagrantfile is riddled with sensitive data, so I'm only pasting the relevant section:

cf.vm.synced_folder hostpath, "/" + guestpath, type: "nfs"

• hostpath is /Volumes/ExternalDrive/git-repos/comp/android-client
• guestpath is android-client

Debug output

https://gist.github.com/nathan-fiscaletti/74e68a5e524582a9908a4da5985b8308

Expected behavior

The shares should be mounted properly.

Actual behavior

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

/sbin/mount -t nfs -o 'nfsv3,mntudp' 172.30.0.1:/System/Volumes/Data/Volumes/ExternalDrive/git-repos/comp/android-client /android-client

Stdout from the command:



Stderr from the command:

mount_nfs: option nfsv3 deprecated, use vers=#
mount_nfs: can't mount /System/Volumes/Data/Volumes/ExternalDrive/git-repos/comp/android-client from 172.30.0.1 onto /android-client: Stale NFS file handle

---

I believe this may be related to the use of an external drive, however I cannot conclusively say that.

Here is the contents of my /etc/exports file after running vagrant up:

/Volumes/ExternalDrive/git-repos/comp/android-client -alldirs -mapall=501:20 172.30.0.12

Might be related to https://github.com/hashicorp/vagrant/issues/10961

[marvinschroeder]

Got kind of the same problem (NFS mounting an external drive on Catalina) and commented my setup/problem in #8704

[nathan-fiscaletti]

It looks like doing what @vintagesucks suggested here (https://github.com/laravel/homestead/issues/1304#issuecomment-545391163) seems to have resolved my problem.

I just needed to grant Full Disk Access to /sbin/nfsd in my macs settings. However I feel like this error message could be caught by Vagrant and a more descriptive error message could perhaps be displayed.

Or perhaps this is indicative of a deeper issue in Vagrant that needs to be resolved.

@nathan-fiscaletti Confirmed that this workaround works. However, are there any security issues that we should be aware of?
