Yes I had " zpool set autoexpand=on tank" and yes I have a backup. After replacing all the disk: $ zpool set autoexpand=on tank $ zpool replace tank /dev/sdb /dev/sdd # replace sdb with temporary installed sdd $ zpool status -v tank # wait for the replacement to be finished $ zpool replace tank /dev/sdc /dev/sde # replace sdc with temporary installed sde $ zpool status -v tank # wait for the replacement to be finished $ zpool export tank $ zpool import tank $ zpool online -e tank /dev/sdd $ zpool online -e tank /dev/sde $ zpool export tank $ zpool import tank Now it sees all the space!

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
