ZFS also had expansion for a long time but it was offline expansion. I don't know if btrfs has also had online for a long time?
And shrinking no, that is a big missing feature in ZFS IMO. Understandable considering its heritage (large scale datacenters) but nevertheless an issue for home use.
But raidz is rock-solid. Btrfs' raid is not.
- unsnap_biceps 2y agoRaidz wasn't able to be expanded in place before this. You were able to add to a pool that included a raidz vdev, but that raidz vdev was immutable.
- wkat4242 2y agoOh ok, I've never done this, but I thought it was already there. Maybe this was the original ZFS from Sun? But maybe I just remember it incorrectly, sorry. I've used it on multi-drive arrays but I never had the need for expansion.
- ryao 2y agoYou could add top level raidz vdevs or replace the members of a raid-z vdev with larger disks to increase storage space back then. You still have those options now.
