I'm running TrueNAS Scale on my MS-01s, with various sizes of QNAP JBODs. I had a drive faile in my TL800S, the other day. After replacing the drive, the QNAP took zero notice of that, and did not spin up the drive. I had to shutdown the TrueNAS Scale server, then power cycle the QNAP before it would recognize the drive, then restart the Scale server. Zero transparent replacement of a failed drive. BOO. Not happy AT ALL.
