Has anyone thought about taking new drives and incorporating them into the pool in a way that spreads them across multiple vdev's as you grow your pool?
So for example you start with a 6 drive Z2 pool and then a couple of years later you prepare to add a 2nd vdev of 6 drives in Z2 to your pool, so you buy another 6 drives and instead of just making the new vdev with them, use the replace option to one at a time swap out 2 of the drives in the original vdev with 2 new drives and then make the new vdev with 4 new drives and 2 older drives.
Then when adding the 3rd vdev a couple of yrs later do the same thing remove another 2 of the original 6 drives replacing them with new ones and making the 3rd vdev with 4 new drives and 2 old?
1st vdev WWXXYY 2nd vdev WWXXZZ 3rd vdev WWYYZZ 4th vdev XXYYZZ
W drives 6yrs old / X drives 4yrs old / Y drives 2yrs old / Z drives New etc
Would this make your pool any more resilient by making the vdevs more resilient or would it be more effort than its worth?
