Start eg. with 8 1TB hard disks in one raidz2 (da0-da7)

replace 1 disk at a time with a 2TB disk
using zpool replace tank da<x>

Using ZFSv28, do

zpool set autoextend=on tank
zpool online -e tank da0
zpool online -e tank da1
zpool online -e tank da7

and have 11.3 GB available instead of 5.6 GB.
Nice. Very nice!

Many thanx to all who made this possible!

Best regards,
