Gornil Posted February 21, 2021 Share Posted February 21, 2021 Hi, I'm very new to unraid and just installed it on a machine I have. I've mounted the harddisk and set a parity drive. I've added 3 drives to the array. It's now doing a parity sync, but I have an Incredible ammount of errors in the view. And it keeps rising. For all 3 of the array disks I have a total of 221 305 errors right now (~80% complete), with this error repeeting "UNRAID kernel: print_req_error: I/O error, dev sdd, sector xxxxx". I've tried to google, but I cant find anyone who have had this error during parity sync. What should I do? Should I cancel the parity sync? And what can the fault be? I've read that this erro can be something with the sata cables between the controller and disk. But right now I'm just wondering if I should let the parity sync contiune, or just cancel it.

itimpi Posted February 21, 2021 Share Posted February 21, 2021 You should definitely cancel the parity sync as something is wrong. Which device is /dev/sdd? You are likely to get better informed feedback if you attach your systems diagnostics zip file (obtained via Tools->Diagnostics) to your NEXT post in this thread. Quote Link to comment
Gornil Posted February 21, 2021 Author Share Posted February 21, 2021 Thank you for your quick reply, really apreciate it. I've canceled the parity check now. I've added a screen shot of the Main dashboard and devices I have connected. I've also attached the diagnostic zip file as well. unraid-diagnostics-20210221-1550.zip Quote Link to comment
itimpi Posted February 21, 2021 Share Posted February 21, 2021 CRC error counts indicate a connection problem - typically the cabling rather than the drive although I must admit I do not think I have ever seen a count that high so I could be wrong. They are occurring on all 3 drives so that suggests to me that there has to be something that is common to all 3 drives that is causing the problem. Quote Link to comment
JorgeB Posted February 21, 2021 Share Posted February 21, 2021 Update the LSI firmware to latest, CRC errors are a known issue of the version you're using. 1 Quote Link to comment
Gornil Posted February 21, 2021 Author Share Posted February 21, 2021 Thank you both for your help! Seems like upgrading the LSI FW and BIOS by follwoing your guide JorgeB fixed the issue. I've now restarted the parity sync and it's about 12% complete without any errors. Thank you again. 1 Quote Link to comment
