--k+w/mQv8wyuph6w0 Content-Type: text/plain; charset=utf-8 Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hello, I have a machine with a simple zfs root mirror pool (2 disks) that I'd=20 like to shrink and I wondered what would be the best approach to do=20 this? I was thinking of booting on a usb stick, remove one physical disk from the mirror, gpart resize the partition, create a new zpool, and finally a pair of zfs snapshot / send from the old pool to the new one .. Would that work? Any caveats? Thanks!
