Need help swapping out different HDDS model

[ctransj]

Hello,
How I swap out the disks from a heathy mirror volume with a greener disks with the same capacity.
I know that I need to swap out one and let the system rebuilds the volume then do the other one.
What are the steps to tell freeNas to rebuild the volume? I want to replace Seagate constellation with WD red 2TB
Thanks
Calvin

Consult the manual. It gives steps for replacing drives. Just follow it step by step and you can't go wrong.

See message #4 in this thread: Mirror-with-ZFS

paleoN recommends creating a 3 or 4-way mirror and detaching the old drives after finishing the swap.
