I'm just beginning to set things up, and I can't seem to get the cache drive to work.  

 

Initially setting things up, I am able to select the drive.  But then it gives me an 'unmountable: no file system' error.  There is an option to format it,  but it doesn't do anything.  If I stop the array, the drive disappears.  The only way I've gotten it to reappear again is by wiping the USB drive and starting it over again.  But then I run into the same issue.

There's a problem with the NVMe device, it's dropping offline:

Apr 15 10:36:23 KanNAS kernel: nvme nvme0: controller is down; will reset: CSTS=0xffffffff, PCI_STATUS=0x10
Apr 15 10:36:23 KanNAS kernel: nvme 0000:2e:00.0: enabling device (0000 -> 0002)
Apr 15 10:36:23 KanNAS kernel: nvme nvme0: Removing after probe failure status: -19
Apr 15 10:36:23 KanNAS kernel: nvme nvme0: failed to set APST feature (-19)

 

Booo!  Hopefully it's the drive and not the slot.  Thanks!
