I had a drive that died, I put it in to start the parity rebuilt but one of my other drives is not wanting to connect. I've tried swapping SATA power and data cables with other known good ones and that didn't resolve it. Unraid sees the drive but wants to emulate it, either way I can't start the rebuild because this one drive isn't reporting correctly. I did a smart test on it last night and that showed it fine. diagnostics-20230910-1134.zip

It recognizes it, it just considers it disabled. I guess we could New Config it back into the array. New Config will accept all disks assignments so none are disabled. Then we can re-disable disk4 so it can be rebuilt (after making sure emulated disk4 is mountable). Before following these instructions, wait a few hours to see if @JorgeB has any other ideas. This process isn't documented, but we have used it many times. It is very important to follow the instructions precisely. Go to Tools - New Config, Retain All, Apply. Not entirely sure it will keep the disk4 assignment since it thinks it is wrong. If it doesn't, assign disk4 before continuing, leave all other assignments as they are. In Main - Array Operation, check BOTH Maintenance mode and Parity valid checkboxes, then start the array. Stop the array, unassign disk4, then start the array. This will disable and emulate disk4. Then post new diagnostics so we can see if emulated disk4 is mountable.

Not sure why this drive won't join the array.

Sweet. The reboot was the trick. All drives are looking good now. Thanks for the help @JorgeB and @trurl

One last diag to make sure the PCIe errors are not logging.

Be sure to check your lost+found share (all on disk4) for anything repair couldn't figure out.
