@diamond_wolf Thank you Very much, this worked for me!
I gave ChatGPT your instructions and it gave me these detailed instructions which may be helpful to those not super well verse with the linux command line
-
Prepare the SSD Disk:
Make sure the SSD is properly shut down and disconnected from the old server.
-
Prepare the New Server (Fresh Install of Umbrel OS 1.3 / 1.22):
You’ve already created a bootable flash drive with Umbrel OS 1.3 and installed it on your new server.
Boot the new server from the flash drive and complete the Umbrel OS installation process.
DO NOT install any apps yet, as this is a fresh Umbrel install, and you need to migrate the data from the SSD.
-
Migrate the SSD Disk:
Shut down the new server once Umbrel OS is installed.
Plug the SSD into the new server.
-
Mount the SSD to the Correct Location:
Power on the server and open a terminal.
Create the mount directory for the SSD:
sudo mkdir -p /mnt/umbrel-ssd
This ensures the directory /mnt/umbrel-ssd exists before you mount the SSD.
Find the UUID of your SSD (you will need to match the correct UUID for the SSD):
sudo blkid
This will list all available disks and their UUIDs. Find the UUID for your SSD (it should match the one you were using previously).
Edit /etc/fstab to mount the SSD at /mnt/umbrel-ssd:
sudo nano /etc/fstab
Add the following line (replace UUID=e9ae3217-6a06-4721-b725-78e6524b4272 with your actual SSD UUID):
UUID=e9ae3217-6a06-4721-b725-78e6524b4272 /mnt/umbrel-ssd ext4 defaults 0 0
Save and close the file (Ctrl+X, then Y and Enter to confirm).
Mount the filesystem:
sudo mount -a
Verify the mount: You can verify that the SSD is mounted correctly by checking the mounted filesystems:
df -h
This will list all mounted filesystems and show you the details, including /mnt/umbrel-ssd and its usage.
-
Stop Umbrel Service:
Stop the Umbrel service on the new machine before making any changes to the configuration:
sudo systemctl stop umbrel
-
Move the Umbrel Data:
Change to the /home/umbrel directory:
cd /home/umbrel
Backup the current umbrel folder (in case something goes wrong):
mv umbrel umbrel.bak
Create a symbolic link pointing to the data on the SSD:
ln -s /mnt/umbrel-ssd/umbrel umbrel
-
Start Umbrel Service:
Finally, restart the Umbrel service:
sudo systemctl start umbrel
I did notice after updates it does not automatically re-mount the disk which is annoying would it be advisable to do the following to avoid that:
- Ensure Umbrel is Stopped:
First, stop the Umbrel service to prevent any data changes during the migration:
sudo systemctl stop umbrel
- Copy Data from the SSD to the Internal Storage:
To copy the entire umbrel folder from the SSD to the internal storage, you need to decide where you’d like to move the data. For example, you can copy it to the default location on your internal storage, which is /home/umbrel.
Assuming the SSD is mounted at /mnt/umbrel-ssd and you want to move it to /home/umbrel on the internal storage, use the following command:
sudo cp -r /mnt/umbrel-ssd/umbrel /home/umbrel/
This will copy the umbrel folder and all its contents from the SSD to the internal storage.
3. Ensure Proper Ownership and Permissions:
After copying the data, you need to make sure the ownership and permissions are correct. The umbrel user must own the files:
sudo chown -R umbrel:umbrel /home/umbrel/umbrel
- Remove the SSD:
After ensuring the data has been copied successfully and the permissions are set, you can safely remove the external SSD from the system.
5. Remove the Mount Point (if no longer needed):
If you no longer want the SSD to mount automatically, you can either remove or comment out the line in /etc/fstab that was used to mount the SSD. You can do this by editing the /etc/fstab file:
sudo nano /etc/fstab
Find the line that mounts the SSD (it will look something like this):
UUID=e9ae3217-6a06-4721-b725-78e6524b4272 /mnt/umbrel-ssd ext4 defaults 0 0
Either remove that line or comment it out by adding a # at the beginning of the line.
Example:
UUID=e9ae3217-6a06-4721-b725-78e6524b4272 /mnt/umbrel-ssd ext4 defaults 0 0
Save and exit (Ctrl + X, then Y and Enter to confirm).
6. Verify Everything:
Ensure that the umbrel folder on /home/umbrel is accessible and has the right permissions.
Start Umbrel again:
sudo systemctl start umbrel
You can also verify that the server is running correctly after the migration by checking the status of the Umbrel service:
sudo systemctl status umbrel
