Phoronix: OpenZFS 2.2-rc3 Released With Linux 6.4 Support

It appears the OpenZFS 2.2 file-system driver for Linux and FreeBSD systems will see its release very soon while out today is the third release candidate...

Kick ass. Once the Linux side of block cloning (reflinks) is done OpenZFS will cover practically every niche feature of every mainstream file system.

Also, my replacement 4TB SSD is arriving today. Because they're cheap now, I also bought a 1TB NVMe to act as a persistent L2ARC (l2arc_headroom=0) for my games pool. I figure why not? Worst case scenario is it uses up too much ram, I say screw it, and use it as a 1TB Linux root. Win Win situation...aside from having to drop an unexpected $160 on a new SSD due to a failing HDD...nothing win about that...but OpenZFS saving my ass due to 1 of 3 disks going bad is a Major Win. Hopefully the 1TB L2ARC ram usage isn't too bad with a 1M recordsize.

I'll let y'all know if my games (currently Death Stranding DC) suddenly start loading faster....after the 2nd or 3rd launch

Hopefully, this release will finally include RAIDZ expansion, as announced previously.

No it won't. There's still 0 support for shrinking or restriping. Unless that happens, ZFS is a no-go for anyone who isn't an enterprise that can buy new disks in bulk, but still plans on expanding their storage one day.

How about rebalancing data across different vdevs in a pool, will this ever be a thing?

People that care about expanding cheaply should probably be using a pool of mirrors. You only need 2 disks to grow, and performance is excellent. Last I checked, 14TB drives were still the best GB/$ option, and many home users probably don't have room for more than 4 drives anyway. I.e. use a 4 disk RAID 10 vs. a 4 disk RAID Z1/Z2. ~28TB is a crap ton of space for most people. If you can fit / afford more disks, just keep adding them in pairs.

Hold on. There is an ongoing project from FreeBSD foundation to implement RAID-Z expansion. It is not something that will never come.

Afaik its actually already been implemented in OpenZFS core, it just needs to be ported to Linux

I still want: Rebalancing between vdevs, Tiered Storage and online defragmentation.
I don't care about raidz expansion: But many users want that too

Without Oracle's toxicity, that would be Linux default fs...
