Mount Synology NFS share to Ubuntu 20.04LTS

Mounting a Synology NAS on Linux is simple, but can present challenges and potentially waste valuable time. This repository outlines the procedure to mount a Synology DS1821+ (DSM 7.1.1) on an Ubuntu 20 system. The outlined steps are likely compatible with other Synology models and Linux distributions, requiring minimal modifications if any.

On the Ubuntu 20.04LTS System

1. Click the pull-down menu icon on the top-left bar
2. Goto Settings
3. On the Ethernet (...) connection in use, click on the gear
4. Goto IPv4 and take note of the IPv4 Address. Ex 150.61.178.19

On the Synology box

1. Goto Control Panel
2. Click Shared Folder and find your share you want to mount
3. Click Edit
4. Goto NFS Permissions
5. Click Create
6. In the Hostname or IP box, enter the Ubuntu 20 IPv4 Address found above
7. Click save
8. Take note of the Mount path located at the bottom of the window. Ex /volume1/jagraz
9. Click save

On the Ubuntu Box

1. Open Terminal and type:

sudo apt-get install nfs-common -y

2. Make a directory to mount to using the command below. Replace my_mount_location for the directory name of your choosing

sudo mkdir /media/my_mount_location

3. Change the access premissions, at the Open Terminal type:

sudo chmod -R 755 my_mount_location

4. At the Open Terminal, type:

sudo gedit /etc/fstab

5. At the bottom of the fstab file, type:

# automount from synology box
150.65.138.4:/volume1/shared_folder /media/my_mount_location nfs nouser,rsize=8192,wsize=8192,atime,auto,rw,dev,exec,suid 0 0

Where:
150.65.138.4 is the static IP of the Synology box
/volume1/shared_folder is your mount path shared folder noted earlier
/media/my_mount_location is the folder created in step 2

6. Save the fstab file and on the Open Terminal type command below or reboot:

sudo mount -a

7. Navigate to the folder created in Step 2, files should be there

Troubleshooting

1. Remove the text in the fstab file from step 5, reboot, and start over
2. Make sure the permissions on the mounting directory in step 3 are correct
3. Verify the IP addresses for the Ubuntu machine and Synology box are correct
4. Verify the IP address entered in Hostname or IP box is correct
5. Check directory/files permissions. Check user "id -u" and if need be, change permissions using the code below:

   sudo chown -R $(id -u):$(id -g) /path/to/directory
