check-smart.rb throws: CheckSMART UNKNOWN: No SMART capable devices found

And this is output from lsblk:

# lsblk -nro NAME,TYPE
nvme0n1 disk
nvme0n1p1 part

nvme0n1p2 part
md1 raid1
nvme0n1p3 part

NVMe drives require having SMART capabilities, so smartctl will not output that the device has capability.

If I understand things correctly, NVMe drives have basic SMART capabilities. There just aren't optional ones that can be turned on/off.

Unlike ATA/SATA, NVMe drives have no optional SMART support which could be unavailable or disabled. The NVMe SMART/Health Information log is mandatory.

See https://www.smartmontools.org/ticket/1134#comment:10

SMART/Health Information (NVMe Log 0x02) seems to be something to scan for in the smartctl output, in the find_devices method:
