      Also, note that doesn’t increase the stripe size for old data; it’s just for future writes.

      But you could copy the old data to a new location and it would take advantage of the new stripe size.

      I literally just got bigger drives for my array last week. So happy I put it off.

        So did I, yesterday, but I still think I have to rebuild because I’m reducing disk quantities :(

      How does it work before this release?

        It used to be that you couldn’t grow the pool, so you needed all of your drives up-front.

        Now you can start with four drives and slowly grow over time to whatever your target goal is. It’s much more friendly for home labs/tight budgets.

          That’s good to hear. I assume people saying “ZFS” are usually referring to this OpenZFS (and usually not Oracle ZFS)?

            Oracle ZFS is so obscure by now that it’s irrelevant.

            As usual with Oracle products, it’s just a means to squeeze poorly led companies.
