I'm new to unraid and have just finished configuring my first unraid server. I'm starting small and have the following configuration:
Host: Ryzen 7 MiniPC
Cache Drive: Internal 500GB M.2 nvme
Array: 1x 8TB USB3 drive (disk1), 1x 3TB USB3 drive (disk2)
Parity: none
Disk2 was previously attached as a simple ext4 drive to a Pi4 server that was doing some basic things. When I setup the Unraid server I did it with only the cache and disk1. Then I manually mounted Disk2 and copied all the existing files I had to the share. Once I was sure that was successfully copied I unmounted Disk 2, formatted it and added it to the array.
With everything working, I shutdown the server and moved everything to another room where it would live moving forward. Upon restarting the server in it's new location, it detects all the attached drives properly, but it's not showing that disk2 is "wrong" and the array won't start.
Questions:
1. What, if anything, did I do wrong?
2. What, if anything, can I do to get back up and running?
3. Is the data now unrecoverable because I didn't have a parity disk?
Thanks for your help!
