I rebooted my server last night right before I went to bed and when I woke up it wasn't running. It woulnd't boot/post so I cleared CMOS and changed my BIOS settings back to what they were before and now Unraid is running again. The problem I'm having now is that one of my array disks is missing and says no device. I downloaded a program for Windows to read XFS file system and plugged the drive in and it works fine on the Windows machine and all files are accessible. This is one of 3 external USB drives that have been running for quite a while now and I've never had this issue. I've tried plugging into all other USB ports and swapping cables with the other 2 drives. The cables all work fine as do the ports for the other drives. Please help.

 

 

Specs:
 

R5 2600x, 1650ti, 64GB RAM, 7x 8TB hdd, MSI x470 gaming max, 650w psu

It's working now but I have no idea why.

Okay, so no it's saying all 3 external drives are unmountable: not mounted. This is after starting the array. Here's a new diag

There are multiple duplicate UUIDs, please post output of blkid

I decided to check and see if any drives were mounted while the array is stopped and the drive I was initially having issues with shows up. 

I wanted the output with the array started, but usually duplicate UUID means the disk you're trying to mount is already mounted, so reboot, start the array, and if you still get the same errors post new diags and the output of blkid with the array started.
