Hello,

I am struggling a bit as to what are the best steps to take. As the title says I get sector reallocation warnings at a very fast pace and it's not stopping, from reading around this signals the drive will die and can/should be replaced preemptively (given that the number is not somewhat stable but it's ramping up). I originally thought I could just unassign parity 1 drive and restart the array which would result in the array being protected by a single parity drive. I was told on discord that removing parity 1 will require parity rebuild.

What are the best steps to take here and at any point (e.g parity rebuild) do I run into the risk of losing data if another drive (no more than 1) were to die? I would assume not given that dual parity should protect the array even during parity rebuild, but since it's the parity 1 drive that is being removed I don't want to make conclusions based on assumptions.

Thank you!

Discord was incorrect. A parity rebuild is only required if adding a new parity drive or replacing a parity drive. Simply removing parity1 and restarting the array will bring up the array protected by parity2 against a single drive failure.
