This process is very well documented :-) You need to set autoexpand for the pool to "on" before it can grow to utilise the extra space. Also see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=216881 there's a bug which causes zpool detach to hang if autoexpand is set to "on". I don't know if this also affects zpool replace but to be safe leave autoexpand set to "off" until after you've replaced the last drive. -- Mike Clarke
