n8girard Posted November 20, 2020 Share Posted November 20, 2020 I have been having hard disk failures multiple days this week resulting in full drive rebuilds on several BRAND NEW 10TB IRONWOLF SEAGATE NAS drives. I know it's not the drives, though they have replaced the first ones already under warranty just to be safe. It's following a pattern though and this has happened at least 4 times already with the same symptoms: One of my drives goes down and gets my attention. I have a Parity drive that reads 22,533,332,543,025 Reads and 22,533,332,543,360 Writes (which is impossible because since booting it's only been 3hrs.) Note this has also happened within just a few minutes of me checking the server which is also impossible. See attached screenshots: Inevitably there are some drives with errors on them and it stops those drives automatically. Troubleshooting steps taken: Completely removed drives with error on them and replaced them with brand new drives. These new drives fail within a week with same symptoms as before. Replaced system Cache drive with a new one. No errors on it to date but problem still occurring. Replaced the Flash drive with a new one and moved my registration key over. Upgraded my OS and 3 drives failed to be recognized: Parity, Disk 3 and Disk 4, all three of my 10 TB Ironwolf Seagate drives. Restored Flash drive to previous state and old OS v 6.4.1 and now back to only one disk failed, others were recognized. Rebuilding Disk 4 now. I also included my system info. I believe my next step is to replace the Parity drive and rebuild it. Any other recommendations? Anyone seen this behavior before? Quote Link to comment

JorgeB Posted November 21, 2020 Share Posted November 21, 2020 I have a Parity drive that reads 22,533,332,543,025 Reads and 22,533,332,543,360 Writes This is a symptom of a drive dropping offline, diags are after rebooting but you're using a Marvell controller and those are known to cause that and other problems, all 3 disks showing errors on the GUI are unsurprisingly connected to it.

n8girard Posted November 24, 2020 Author Share Posted November 24, 2020 @JorgeB This is likely due to a PCIe SATA card I installed to expand my SATA capabilities. Evidently it's garbage. Any recommendations on a good quality card that won't drop my drives? Quote Link to comment
JorgeB Posted November 24, 2020 Share Posted November 24, 2020 How many ports do you need? There aren't many good 4 port options, there's the 5 port JMB385 controller, though most times you can get an used 8port LSI HBA for about the same. Quote Link to comment
