tnorman Posted May 29, 2021 Share Posted May 29, 2021 (edited) The Unraid system ran a Parity check which passed. I had turned off all normal running dockers. So I restarted them about 12 hours after the system had finished the parity check. As the the dockers started back up I got 12 read errors on one my oldest hard drives. The array stopped. And then I got a notification that everything returned to normal from Unraid. I've left the array stopped as my disk 4 has a red X for disabled and is being emulated. I checked the disk status and ran a extended status on it. Everything looks fine to me. I'm not seeing a red flag besides the age of the drive in the diagnostics, but I may be missing something. I'm wonder if it might have just been a cable connection problem. I've been trying to solve a heat issue that has suddenly come up over the past month where the machine shuts down for some reason. I currently have the case open with a large fan blowing straight on it, so I figure wires might have been jiggling a bit? I'm not sure. I found it odd that Unraid reported the problem and then said everything was okay, but I assume that was because it was now emulating the disabled disk. Could someone take a look at the diagnostics and see if I'm missing something. I actually saw some read errors on another drive that is the same make and just as old, but it isn't giving issues. I'm planning on replacing a couple drives, possibly 3 of the oldest drives, just because they are running pretty high in hours usage. Or I might just add a parity disk so I have 2 instead of one in case 2 drives fail. Haven't decided yet. It depends on if I need to replace the current disabled drive. Thank you for your help!

JorgeB Posted May 29, 2021 Share Posted May 29, 2021 Disk looks fine, replace/swap cables to rule em out and rebuild assuming the emulated disk is mounting correctly. You also have what look more like connection issues with the cache drive, but since it dropped offline there's no SMART report. 1 Quote Link to comment
tnorman Posted May 29, 2021 Author Share Posted May 29, 2021 I didn't even look at the cache drive. I'll take a look. Thank you! Quote Link to comment
tnorman Posted May 29, 2021 Author Share Posted May 29, 2021 I must have unplugged the cache drive from power as I was trying to locate wires for the fans. Plugged it back in and it is running an extended self check right now on it. Quote Link to comment
