simple zfs raid 1 replace failed disk

[ale.ab]

Hello,
i'm try to replace an hdd failed.

i have simple proxmox VE with 2 SSD disk 512GB
1 is dead.

i try to replace with 1 hdd SATA 750gb, because is on my lab is not a problem.

i detach ssd broken, attach hdd and on ssh:
zpool replace rpool 9569750636164580599 /dev/sdb

now with
zpool status -v rpool
state: ONLINE

so seems ok, but if i run
fdisk -l

Disk /dev/sda: 476.94 GiB, 512110190592 bytes, 1000215216 sectors

Second too late.
And replacing a SSD with a HDD will slow down the write performance of the remaining SSD to a HDD level.
