Hi good people of the Unraid community. I recently reached the limit of my current setup and decided to upgrade to a bigger one. I have some Unraid experience, so I went in with what appears to be overconfidence in hindsight.
I moved all my drives to the new server and booted up Unraid and saw that the drive assignments had changed. I clicked new config and rebooted the server and at this point I noticed that one of my drives is not showing up. I then spent all day diagnosing and came to the conclusion that the drive is dead as it won't show up in the bios or my other PC.
Now I haven't booted the new server up again because I am not sure how to proceed and want to minimize the chances of me making mistakes that would result in data loss.
What are my options for recovering the data? I have a spare 10TB drive that I can use to replace the dead 8TB one. How do I go about setting up the array again and not lose data in the process? Any and all help is immensely appreciated.
