donuts13 Posted February 28, 2023 Share Posted February 28, 2023 I have two drive that are disabled. I have moved them to Know good drive bays. even to location on another controller card. with known good drives. First it was only one but in the process of troubleshooting bad drive bay, the second came up. Smart checks are ok but this dam error will not go away after power cycles etc. Now there are No UDMA CRC error counts but still Unraid will not give it a green dot. Pls help! prime-diagnostics-20230228-0636.zip Quote Link to comment
itimpi Posted February 28, 2023 Share Posted February 28, 2023 Once you get a drive disabled (Red ‘x’) then the way to clear that status is to rebuild it. Before doing so I suggest you post your diagnostics with the array started in normal mode so we can see if it looks like the disabled disks are being emulated correctly. Quote Link to comment
donuts13 Posted February 28, 2023 Author Share Posted February 28, 2023 I posted Diagnostics, Here is a new set with the array started. the last time this happened i lost ~80TB. Rebuild has never worked. prime-diagnostics-20230228-0705.zip Quote Link to comment
JorgeB Posted February 28, 2023 Share Posted February 28, 2023 Diags are after the problem so we can't see what happened, but the disks look OK so most likely a power/connection problem, emulated disks are mounting, assuming the contents look correct you can rebuild on top, ideally after checking/replacing the cables for both.

Rebuild should work without issues as long as there is no file system corruption before starting the rebuild and parity is valid and no other drives have issues. if you want to play safe you should rebuild to a different physical drive keeping the original untouched so that it is available for recovery purposes if the rebuild is not as expected.
