timethrow Posted January 18, 2022 Share Posted January 18, 2022 Hi, I have 2 Disks showing as Disabled and having Read Errors, this originally started part way through my scheduled monthly parity check. The disks don't show any smart issues that I can see, and when I try and run a Self Test (Short or Extended they keep disappearing) and after a few seconds (~30) they come back again. Its for Disks 10 (sdz) and 15 (sdx). I have a few times managed to get the Short Self Test to complete, but its rather intermittent, when it does complete, it does not report any errors. These 2 disks are both connected to a SAS expander, but there are 13 other drives also connected to this expander and these all seem to work ok at the moment. I have tried rebooting etc, and I also tried disabling the VM PCIe ACS override but no luck with that. No Hardware changes made for a few months and no major software changes either (including no BIOS or Firmware updates). Diagnostics attached, does anyone have any suggestions please? Thanks unraid-diagnostics-20220118-1316.zip Quote Link to comment
JorgeB Posted January 18, 2022 Share Posted January 18, 2022 Disks are dropping offline, this is usually a power/connection problem, try swapping slots/cables with different disks and see if the issues follows the disks or not. Quote Link to comment
