tucansam Posted August 10, 2018 Share Posted August 10, 2018 This is my backup server, it comes on once a week to do a copy of changed files from my primary. Has run 100% for years. Hasn't moved (I say that because it might be a loose controller card) but tonight's copy gave me zillions of CRC errors across every disk in the array. Your advice is most welcome. ffs1-diagnostics-20180810-0449.zip Quote Link to comment
John_M Posted August 10, 2018 Share Posted August 10, 2018 If it happens to one disk it's usually a bad cable. When it happens to eight disks simultaneously I'd suspect that "loose controller card". If it proves not to be that the next thing I'd suspect is the power supply or the power distribution to the disks. Quote Link to comment
anhloc Posted August 10, 2018 Share Posted August 10, 2018 I was getting these errors for the first time ever, but nowhere near as bad as yours. Mine was spitting out 1 or 2 a week, and only on certain drives. In my case, it ended up being a defective SFF-8087 to breakout 4xSATA cable that I had. Replaced it and it's been three months, not a single one since. Given that you have 8 drives that are spitting out errors, I truly hope that it isn't an HBA card that has gone bad. If you have a spare HBA or data cables, I'd swap and see if that alleviates the issue. Thankfully those errors *shouldn't* cause any data corruption issues, from what I've seen (checksums for random files on my drives came back fine,) however, I've had a total of 14 errors on the 4 drives on the cable, which you've obviously had a lot more of. Good luck. Quote Link to comment
