I just resized my zfs partition from 300GB to 500GB , however the additional 200GB doesn't append into the current zfs pool.

The additional 200GB is indicated at expandsize as below, how can I add it into the total size to make it a full 500GB pool?

Re: ZFS expandsize?

I've recently done this on a RAID-Z pool and the extra space only became available after I replaced and resilvered every drive. What kind of pool do you have? Is it just a single drive?

Re: ZFS expandsize?

In light of this example provided by @belon_cfy, I'm wondering how one should interpret:
expandsize        This property has currently no value on FreeBSD
from zpool(8). The wording is clumsy and therefore its meaning is not clear, at least to me.
