September 24, 20241 yr So having experienced enough hard drive failures in my lifetime, I'm familiar with bad sectors etc. that can mean the impending death of a drive. While traveling a few days ago, I got a notification from my server that I had a disk with errors in the array: "Unraid: Unraid array errors Warning [UNRAID] - array has errors 1727017023 Array has 1 disk with read errors warning Parity disk - ST18000NE000-2YY101_ZR54FPSN (sdh) (errors 93)" I VPN'ed in to have a look and noticed that my primary parity disk had been disabled showing 93 errors (still in this status as I haven't taken any actions as of yet). Honestly, I'd rather just RMA the drive as it's got a couple of years left under warranty but I don't know that I've got a valid case for that yet. I grabbed the diagnostics to capture what was present in the log at that time and sliced out this part of the syslog to identify when the server started noticing issues with the disk. There wasn't anything eventful happening leading up to this event (nothing with high I/O activity, no tasks running, etc.) and the other 15 disks on the HBA are all humming along merrily, including 3 others on the same cable. The log showed both read and write errors: Sep 22 10:56:34 Unraid kernel: mpt3sas_cm0: log_info(0x31110d00): originator(PL), code(0x11), sub_code(0x0d00) ### [PREVIOUS LINE REPEATED 24 TIMES] ### Sep

Any thoughts or suggestions are welcomed.
September 24, 20241 yr I would suspect cabling or connection errors. Power stability can also cause that sort of thing, a PSU may get weaker as it ages without fully failing. SATA power splitters are also a common problem.
September 24, 20241 yr Author The PSU is a 1000w Corsair that I bought a few months ago new so I'd be less inclined to suspect PSU but duly noted. I'm averaging about 200w of usage per the total draw on my UPS. I bought a larger PSU specifically to have ample SATA power connections to avoid using any splitters and thankfully don't have any of those in use. I concur on disliking them and have had some catastrophic failures resulting from those (burnt cables, etc.) so I strictly avoid them now. I also have this machine on a UPS to avoid any power disruptions that would interrupt the array as it's no fun waiting for a parity check for 36 hours. That's why I'm scratching my head at the moment. I've not actually experienced a "false" disk failure before with Unraid since I've only begun using it toward the beginning of the year, so short of just watch and wait and see, do I just clear the errors and restart the array to put that disk back in production?
September 24, 20241 yr Author It's an 8643 SAS to SATA cable and the other 3 drives on the same cable are error-free. Physical inspection has confirmed it's fully seated and no indications of a loose or poor connection. I could get a replacement just to rule it out as it's about all I've got left at this point, aside from the card itself (fingers crossed that isn't it).
September 25, 20241 yr Author Yeah I have a pair of 80mm fans that are directly blowing over the heatsink. They are driven at 100% duty.
