EDIT

I found the issue, it was me!! LOL I thought it had to be a setting I had forgotten and it was, I forgot to enable NFS & Nesting under Features in the Otions of the cotainer, see this image - https://imgur.com/bSiozKS

Thank you to everyone that took the time to reply and offer their suggestions.

Hi All,

Let me start with some basic basic background on my set up, I have a server running Proxmox with some Ubuntu containers. I have a separate server running TrueNas with a share that has both NFS & SMB set up. I can see this share in Windows 11 and read and write to it.

One of the Ubuntu containers is able to see this share via NFS and read and write to it too. I am testing Sonarr, Prowlarr & Qbittorrent Docker containers and got the basics set up, Sonarr can find episodes via Prowlarr of a TV show, hand it off to Qbittorrent to download and then move it from the download folder to the TV folder. Both the download folder and the TV folder are on the TrueNas server.

I then set up a Docker container for AudioBookShelf in the same Ubuntu CT and that can also read and write to the NFS share.

My issue is that I tried to set up another Ubuntu CT on the Proxmox server but cannot seem to access the NFS share on the TrueNas server.

This is what I did (which I think was the same process as the working CT)

  • 1/Create a privileged conatiner
  • 2/ Update and upgrade the CT
  • 3/ Install nfs-common
  • 4/ Create a directory in the CT in the /mnt directory for the NFS share
  • 5/ added this line to the fstab file in /etc 192.168.0.188:/mnt/store/test-share /mnt/test-share nfs defaults 0 0

However, when I run mount -a I get this error message mount.nfs: access denied by server while mounting 192.168.0.188:/mnt/store/test-share

Running df -h does not show the mount obviously but it does in the working CT

As a further test, I cloned the working CT, deleted all the Docker containers and I can still see the NFS just fine.

I have probably missed a step while setting up the new CT but I’m not sure what.

Can anyone offer some help?
