May 23, 20233 yr After my drive failure and corruption a couple a months ago, I set up alerts to let me know if anything was going on. I got an email today that there was an error on my array. When I checked I see that disk 2 is offline and disks 1, 2, and 3 have 669,627,864, 669,627,864, and 669,627,928 errors respectively. The shares are still accessible. Disk 2 is the slot I had problems with last time (I have since replaced the drive) and have had issues with it dropping offline. I am 99.9% sure I have swapped it SATA cables and ports and the issue stayed with disk2 no matter where it was but I can certainly do that again. I learned my lesson last time and gathered logs before I am rebooting. I'm not touching anything until a smart person gives me advice l33tnas-diagnostics-20230523-1848.zip
May 23, 20233 yr Community Expert Disks 1,2,3 have disconnected. Are these all on the same controller? Your jmicron ports are configured IDE instead of AHCI. Marvell controllers are NOT recommended.

Marvell controllers are NOT recommended. Without shutting it down and opening the case, I am not sure. I know I ran out of SATA ports on the motherboard and have a contoller card with 1 drive plugged into it. The rest are plugged into the motherboard. It would seem that the Marvel controller is the one built into the motherboard. The jmicron must be the one with the single drive plugged into it. At this point it seems like my best (and cheapest bet) would be to ditch the onboard Marvel controller and get a PCI card that can support 8 devices? Or maybe even better, another 4 port jmicron? I found the information about the Marvell controllers NOT being recommended as they can drop drives, just like mine is doing. I might actually have another SATA controller up in the attic in my PC graveyard. Am I safe to shut down and verify what drive is connected where? If I so should I restart in maintenance mode? After that, what are my next steps? I do have EVERYTHING backed up at this point.
May 24, 20233 yr Community Expert A reboot should bring the array back, then post new diags after array start.
May 24, 20233 yr Author I gave it a reboot and it came back up. Disk 2 is showing as "device is disabled, contents emulated" Here are the new diagnostics. l33tnas-diagnostics-20230524-0731.zip
May 24, 20233 yr Community Expert Solution You can now rebuild on top, ideally using a non Marvell controller.
