strike Posted July 7, 2015 Share Posted July 7, 2015 So I got an mail from my unraid box yesterday that disk 3 has 2 pending sectors.. As I understand this is something that has to be fixed, no matter how low the number is. Do I have to pre-clear it first or can I just re-enable the drive like it says in the wiki? If no spare is available then follow the next procedure to re-enable the drive. The pending sector count should be zero after rebuilding. If not then replace. I don't have a spare at the moment, so I'm wondering what is the best and fastest way to solve this. Should I just buy a spare, replace and pre-clear the original and have it as a spare or should I re-enable the drive and rebuild, or take the drive offline pre-clear it and then re-enable and rebuild?

dgaschk Posted July 7, 2015 Share Posted July 7, 2015 Optimally, you should have a pre-cleared spare on hand. (Or a large enough cache drive that can be moved into the array.) Buy a spare, pre-clear, and keep it as a ready spare. How old is the drive? If it's new, then rebuild onto itself. If it's old, then pre-clear and rebuild onto itself. Finally, do a parity check. If the pending sectors persist then the drive will have to be retired. Link to comment
strike Posted July 7, 2015 Author Share Posted July 7, 2015 The drive is just a year old. Well, technically I have a spare, I have 2 drives in the array without any data on it, so I could just shrink the array and keep one as a spare. I have lots of space anyway so, but yeah thanks for your reply, I will mark this as solved now. Link to comment
