Expand partition containing a zpool

I installed arch on zfs almost a year ago, I don't remember how, I set up a zvol (or zpool, sorry if the concept is not right), now I realized that I'm running out of space, and I don't know how grow it.

Afaik, I need to expand the partition first, but I'm not sure how to do it , and searching doesn't give us results either....

ps.- i'm using a gpt disk

Re: Expand partition containing a zpool

Firstly, you need to make sure the “autoexpand” property is set to “on” on the pool (by default it's off).
If there is unallocated space the partition can be expanded into, you can use a tool like parted(8). Make sure you have a backup, it's very easy to get partition manipulation wrong.

If you can't resize the existing partition, you have a couple of alternatives:
A) expand the pool by adding another VDEV
B) use mirrors - attach a new, suitably sized VDEV and detach the old one.
