Phoronix: OpenZFS 2.2-rc1 Brings Linux Container Support, BLAKE3 Checksums, Block Cloning

While OpenZFS 3.0 has been talked about for a few years with macOS support, it doesn't appear to be on the immediate horizon and the OpenZFS 2.2 release is being worked on currently for providing a few new features to this open-source ZFS file-system implementation on Linux and FreeBSD systems...

And the long-running github issue on raidz expansion has finally been closed. The work has been handed off to another OpenZFS developer working under contract from ixsystems to finally bring it to completion and work is well under way.

Are there a comprehensive and well explained filesystem features comparison of modern filesystems? ZFS, Btrfs, bcachefs, XFS, NILFS, F2FS, HAMMER2, NOVA, etc.

It's sad Tux3 seems dead. Not sure if many know about it.

Looking forward to block cloning which will finally bring support for reflink copies!

Ah, that answers a question I had. I was looking forward to finally getting reflink support. Glad to hear it's coming soon.f

am definately looking forwards to these new improvements. just hope it will be spelled out in somebody's blog posts / article somewhere how to upgrade my existing pool. to migrate over, and other flags or options to set to take advantafe of what is... new stuff, which is a bit unfamiliar to me!

note: if you boot off the pool and use grub, you most likely won't be able to use any of this stuff...

- upgrade your zfs packages, update your initramfs (if needed) and reboot
- run "zpool get all mypool | grep feature" to see what is enabled and what isn't
- run "zpool set feature@whatever=enabled mypool" to enable stuff

some features need other features, refer to "man zpool-features" for more information.

It's best not to rely on GRUB for filesystem support anyway. Its filesystem drivers are often slow, buggy and way behind in functionality in general.

Is it FreeBSD only or both Linux and FreeBSD? Does GNU coreutils/cp still need to use the reflinks=auto workaround? Reading the discussions in the PR didn't make that very clear.

O_o looks like this is only for FreeBSD and Linux is not included
