It was a statement, and luckily I was partially wrong, as Vladislav did
made what he wanted to.
However, last time I checked there were no such easy ways to decrease
zpools or increase/decrease UFS partitions.
Or grow mirrored ZFS as easily as single zpool. Or (killer one) remove
added by mistake vdev from zpool ;)
Of course I'm not talking about real hw, rather virtual one.
If you happen to point me somewhere to have such task solved I'd be much
