johnsanc Posted June 3, 2020 Share Posted June 3, 2020 (edited) I am running into serious issues as outlined here... and I think I may have gotten to the bottom of it: After about the 4th round of trying to Parity Check I noticed nearly ALL of my drives have massive and increasing numbers for the following. I found it very odd that I was getting these errors across all sata controllers: Raw read error rate Seek error rate Hardware ECC recovered However there are no errors in the syslog or anything that would indicate an issue as far as I know. Were there actually errors but suppressed due to the P+Q sync corrections? What can cause the 3 bullets above and what should I try to do to fix? Or is this normal? EDIT: Upon closer inspection all but one of the disks are attached to my Intel RES2SV240NC RAID Expander Card + LSI LSI00301 (9207-8i) Edited June 4, 2020 by johnsanc Quote Link to comment

Seagates for example show the actual total values, not just the errors, so any activity will increase them. Quote Link to comment
johnsanc Posted June 4, 2020 Author Share Posted June 4, 2020 Good callout - They are all Seagate. I guess I can just ignore those metrics. Quote Link to comment
