Upgrading from unRAID version 3
Starting with release 4.0-beta1, unRAID Server OS uses a port-based method for assigning hard drives to parity and data disks. This is a consequence of moving to the linux 2.6.x kernel, but is also a much more flexible method.
Follow this procedure:
- Referring to the System Management Utility 'Main' page, make a note of each disk's model/serial number; you will need this information later.
- Shut down your server, remove the Flash and plug it into your PC.
- Drag the 'config' directory of your Flash onto the PC desktop.
- Reformat the Flash and install the latest unRAID Server software. You can download it from here. Make sure the Flash volume label is set to UNRAID.
- Now open the saved 'config' folder on your PC and copy the following files to the 'config' directory of the Flash:
- your registration key file (something like pro.key or similar)
- Right-click your Flash device listed under My Computer and select Eject. Remove the Flash, install in your server and power-up.
- After your server has booted, the System Management Utility 'Main' page will probably show no devices; this is OK, navigate to the 'Devices' page. Using the model/serial number information gathered in step 1, assign each of your hard drives to the correct disk slot.
- Go back to the 'Main' page and your devices should appear correctly. You may now Start the array.
