doblez Posted September 23, 2019 Share Posted September 23, 2019 Hi, I've recently build a new server with some brand new disks and some older SAS drives I got for cheap. I wrote to all of them from my old server through ftp with problems or errors. 5.5TB in total. I then tried to do a parity check and all "hell" broke those with disk read errors. I was extremely confused as to why, so I restarted the server. Tried downloading files from all of the afflicted disks. No errors. But as soon as I start the parity check I get errors for days and I have no clue why. I hope you can help! In advance thanks! dservermain-diagnostics-20190923-2050.zip Quote Link to comment
halfelite Posted September 23, 2019 Share Posted September 23, 2019 (edited) What are the smart Stats on disk 5 and 6 Also could be a bad controller if all start failing. Edited September 23, 2019 by halfelite Quote Link to comment

Smart Stats are included in the diagnostics file and it's all the disks, not just 5 and 6 that fail. Disk 1 (new 4TB Seagate) doesn't provide errors. Quote Link to comment
JorgeB Posted September 24, 2019 Share Posted September 24, 2019 Run a long SMART test on both disks, but more likely a controller/connection/power problem Quote Link to comment

It's a Dell Perc H200 Raid card (JBOD) and a dell r720 with the backplanes connecting to the disk themselves. Quote Link to comment
JorgeB Posted September 24, 2019 Share Posted September 24, 2019 Check/replace cables, can also be the PSU, you'll need to test one thing at a time to rule them out. Quote Link to comment
doblez Posted September 24, 2019 Author Share Posted September 24, 2019 And how would I test the controller (which I'm assuming to be the H200)? Although I doubt it's that since the new disks aren't spitting out errors! Quote Link to comment
JorgeB Posted September 24, 2019 Share Posted September 24, 2019 By using a different one, but controller would be last thing to try, cables and/or PSU are more likely, it can also be the backplane/expander. Quote Link to comment
doblez Posted September 24, 2019 Author Share Posted September 24, 2019 Fair enough - I'll try to have a look. I just find it very weird with two redundant 750W PSU and the fully functioning disks being on the same expander as the "broken" ones. Quote Link to comment
doblez Posted October 2, 2019 Author Share Posted October 2, 2019 I tried all of the above options to no avail and then I figured. Hell might as well try to reformat the disk. Turns out something went wrong when I last cleared and formatted the 5 900gig SAS disks and a data shuffle + reclear subsequent reformat fixed it and I now have 0 errors. Thanks for your help though!
