Openzfs expansion feature COMING!

Post by Moogle Stiltzkin » Wed Jun 16, 2021 2:04 pm

OpenZFS founding developer Matthew Ahrens opened a PR for one of the most sought-after features in ZFS history—RAIDz expansion—last week. The new feature allows a ZFS user to expand the size of a single RAIDz vdev. For example, you can use the new feature to turn a three-disk RAIDz1 into a four, five, or six RAIDz1. ... fs-master/

Broadly speaking, we expect RAIDz expansion to hit production in the likes of Ubuntu and FreeBSD somewhere around August 2022, but that's just a guess. TrueNAS may very well put it into production sooner than that, since ixSystems tends to pull ZFS features from master before they officially hit release status.
So yeah, I'm not holding my breath on that one. My new TVS-h1288X is getting set up as a QTS box for the time being since I don't exactly have the coin laying around to populate it with 8 12TB drives right off the bat, but I will get there.
NAS1: TVS-h1288X 16 GB - 3x WDC WD120EFBX 12TB - RAID5 23.5TB Usable
NAS2: TS-451+ 16 GB - 4x WDC WD6002FFWX 6TB - RAID5 16.35TB Usable
