mounting nfs shares in ubuntu server

During setup of our home NAS my household (mostly me) decided to separate our media services and our media files into two separate servers. This would help to keep our file storage server's resources separate from our application server's resources.

I'd never mounted a network file share before, so I thought I'd document the procedure.

Reading about a Network File System File permissions number calculator

Steps + commands

  1. ssh to your server, mine was internal.
ssh [email protected]
  1. Determine your mount point from the NAS, I did this by running the following on the NAS server.
    • Note: We use an OpenMediaVault server, so our NFS mounts are under /export/
ls -l /export/

# output sample
[email protected]:~# ls -l /export/
total 4
drwxrws--- 2 root users 4096 Dec  8 17:25 MediaShare
  1. Create your mount point
mkdir -p /mnt/your-mount-here
  1. Use the above information to mount to your destination server.
sudo mount -t nfs4 192.168.1.234:/export/MediaShare /mnt/your-mount-here
  1. Now make the mount persist on reboots, if you don't want the mount to persist then skip this step.
sudo umount /mnt/your-mount-here/
  1. Edit the fstab to include our mount, use elevated permissions to allow writes to it
# ... some other stuff
191.168.1.234:/export/MediaShare         /mnt/your-mount-here nfs     defaults        0       0
  1. Set the permissions that you need, I did a chown for my user and set the files to 755
sudo chown -R ${USER:GROUP} /mnt/your-mount-here/

sudo chmod -R 755 /mnt/your-mount-here/
  1. Test and check the permissions to ensure you don't have errors

    1. I first ran a stat to check permissions
    stat /mnt/your-mount-here/
    
    [email protected]:/$ stat /mnt/your-mount-here/
      File: /mnt/your-mount-here/
      Size: 4096            Blocks: 8          IO Block: 4096   directory
    Device: fd00h/64768d    Inode: 3145730     Links: 2
    Access: (0755/drwxr-xr-x)  Uid: ( 1000/ you)   Gid: (    0/    root)

    1. I also created a test file to check for errors
    touch /mnt/your-mount-here/test.py
