khartahk Posted January 26 Share Posted January 26 Hey, I've got a strange issue. Whenever I add a data disk back to the array both my parity and data disk start reporting read errors. - I've tried changing the SATA and power cables (use different power cables from the PSU). - I've also added a 3rd disk and rebuilt the array on that and that worked so I do have a backup in case both my current drives are faulty. - I've ran the extended SMART test on both drives and they had no issues reported - Running read test on only parity drive right now and no errors reported thus far (when both disks added the errors start showing immediately) - I've also moved the data drive to a external disk bay and formated it and checked SMART there the extended test and it also had no errors The issue only occurs when both drives are added to the array. My last option I can think of is to blow the array and recreate it and see if that helps. I'm on unraid 6.11.5 and have 2 Seagate Ironwolf 1TB drives as the array. And I have 2 500GB Samsung SSDs for cache in raid1. All of them are using BTRFS as the filesystem. tower-diagnostics-20230126-1036.zip Quote Link to comment
