rpool
Hi,
In rpool it is a disk of 100gb -a single vdev mado of a disk.
I like to increase to 400gb the rpool.
I am interested if zpool replace rpool old-disk new-disk is a good correct.
I know that if I mirror the old-disk with a new-disk is correct.Then detach the old-disk.
Which is better to use mirror or replace?
