Edit: Found the problem. When I swapped power connections to the new PSU, I rubbed off the tape I had over pin 3 of my shucked WD drives. Problem compounded swapping power cables multiple times until I couldn't read anything. I had forgotten the tape was even there.

 

I recently had my cache nvme disk quit on me, and replaced it with a 2 TB Samsung 990 Pro.  While I was at it, I swapped power supplies and added an additional storage disk to my array. 

 

The new disk showed up as expected under unassigned devices, as did the cache drive, but when I came back up I noticed one of my existing drives in my array was listed as missing. Fearing a bad disk, to isolate the problem I tried swapping the drive to a different SATA port, and then to a different port and cable from the psu. Nothing worked, and worse, I started losing disks from the array every time I booted. Now none of the array disks appear anywhere, but I do see the cache and the unassigned new disk.

 

I have a pro license, so I haven't exhausted any disk limit, and I can't see why a bad SATA port or bus on the mobo would be down, if the new disk shows up correctly.  Could it even be possible I skunked 6 out of 6 disks in an array?  I tried a new USB stick with a 30-day trial install just in case it was a problem with my config getting mixed up, but that shows the same problem.  I'm interested in testing the drives in a different machine, but I don't have another linux box and will likely need to get a USB to SATA drive mount and some software to read XFS...anybody have any suggestions on what may have caused this, or what next troubleshooting steps should be?

Are the disks detected in the board BIOS? Also and if the PSU is modular are you using the pervious PSU cables? They are usually not compatible, even if the brand is the same they may not be.
