ZFS Pool CANT_OPEN

I've run into a strange issue where one of my slots in my JBOD is unrecognizable in UNRAID and shows "Device has an error status: CANT_OPEN". I say one of the slots because I've tried swapping the drives around and it's always that slot. I installed Windows on my server on a spare drive in another slot and confirmed that the drives shows up and is read/writable (just created a simple volume and copied some files to it). What could be causing this?
