July 10, 20241 yr Hello, I have a question about my storage parity (no support needed). I had a 2 x 8TB parity setup, and one of the drives died. I replaced it with a 12TB drive. To my surprise, the array is currently rebuilding as a 12TB array instead of an 8TB array. I have ordered another 12TB drive and will replace the second 8TB drive once the array is done rebuilding, but my question is: how is the array functioning with the current dual parity setup of 8TB (old) + 12TB (new)? Is it working because there’s no drive larger than 8TB in the array, or is the secondary parity drive not functioning at all? Thank you.

The parity operation is always the size of the largest parity drive (if they are different sizes). They the parity drives not need to be the same size as long as the smallest parity drive is at least as large as the largest data drive.
