This guide explains how to mount a hard disk (HDD) on a remote Linux PC, share it via NFS, and mount it on a local Linux PC on the same LAN.

1. Mount the HDD on the Remote PC Using UUID

First, ensure the disk is auto-mounted at boot using its UUID.

Steps:

• Find the UUID of the disk:

  sudo blkid /dev/sdb1
  

  Example output:

  /dev/sdb1: UUID="72957477-b9b8-4771-a450-993396e40f9f" TYPE="ext4"
  

• Create a mount point:

  sudo mkdir -p /mnt/500GB
  

• Edit /etc/fstab:

  sudo nano /etc/fstab
  

  Add this line:

  UUID=72957477-b9b8-4771-a450-993396e40f9f /mnt/500GB ext4 defaults 0 2
  

• Mount it:

  sudo mount -a
  

✅ Your HDD is now permanently mounted to /mnt/500GB.

2. Export the Folder Over NFS on the Remote PC

• Install NFS server if not already:

  sudo apt update
  sudo apt install nfs-kernel-server
  

• Edit exports file:

  sudo nano /etc/exports
  

  Add:

  /mnt/500GB 192.168.0.204(rw,sync,no_subtree_check,no_root_squash)
  

  (Use your local PC’s IP address)

• Apply changes:

  sudo exportfs -ra
  sudo systemctl restart nfs-kernel-server
  

• Verify export:

  showmount -e
  

3. Mount the Remote Share on the Local PC

• Create a mount point:

  mkdir -p /home/manik/500GB
  

• Mount it manually to test:

  sudo mount 192.168.0.207:/mnt/500GB /home/manik/500GB
  

  (Replace with your remote server’s IP)

• Confirm it works:

  ls /home/manik/500GB
  

4. Auto-Mount the Share at Boot on the Local PC

• Edit fstab:

  sudo nano /etc/fstab
  

  Add:

  192.168.0.207:/mnt/500GB  /home/manik/500GB  nfs  defaults,_netdev,user,nofail 0 0
  

• Test it:

  sudo umount /home/manik/500GB
  sudo mount /home/manik/500GB
  

5. Troubleshooting Tips

• “Permission denied” → Check /etc/exports IPs and permissions.

• “Stale file handle” → Remount or reboot both systems.

• “Device is busy” → Use sudo lsof /mnt/500GB or sudo fuser -vm /mnt/500GB.

• Restart NFS services if needed:

  sudo systemctl restart nfs-kernel-server   # on server
  sudo systemctl restart nfs-common          # on client
  

This setup enables smooth and automatic access to shared storage over a local network.
