As a home user of ZFS I would give it an ETA of never. We've been waiting for probably 10 years for this feature, but it's just never been enough of a priority from more serious (paying) users to get worked on.

Not sure if this is a bit late, but I'd like to see ZFS support ;-)

cannot wait for zfs

There was just a talk on it this year, it’s coming but between the time it takes to go stable in OpenZFS and the time it takes to hit downstream (FreeBSD, ZoL) it might not be for a while yet.

I was wondering when that was going to happen. As far as I know, there's a FUSE port of ZFS - no idea how far along that is.

The zfs storage driver isn't production ready yet.

I mean you can’t maintain ZFS normally, and people have been trying to make zfs happen for what… two decades now?

I think you've confused your dates. ZFS has been in development since 2001. It was first introduced in 2005.

Adopting ZFS would take away from Storage Spaces, So sadly I don’t see it happening.

Interesting that it took so long to reach this conclusion. I thought Linux devs stayed away from ZFS mainly due to the licensing which leads me to believe it's not quite as 'obvious' as this post mentions.

Damn, was looking forward to ZFS. Are they working on an alternative?

Five years on and ZFS still remains just out of reach. I'm not a likely user on OS X (anyone got a good use case for laptop use?) but other filesystem + volume management solutions on Linux never seem to match up.

Probably never. ZFS isn't just a filesystem, it was developed to be an entire storage system that's vertically integrated, so ARC is a fundamental part of the filesystem design.

ZFS also has a huge legacy. Right now the license (probably) prevents you from legally shipping a compiled zfs module with the linux kernel, just solving that seems insurmountable. It's also supported on Illumos and FreeBSD, trying to refactor it to use the linux page cache would have a chance of introducing bugs to these platforms.

Not going to happen. It almost happened around 2007, when Sun's Jonathan Schwartz announced it on his blog. Then Apple conceded the development, sticked with HFS+ for another decade, only to eventually roll out APFS.


Why not? There's already support for zfs.

ZFS has now been ported to Windows. With some testing and polishing, maybe it will be something they could adopt in the future (I know, wishful thinking, but the technology is there).

Just use ZFS with Linux? It's been available as kernel modules for I don't know how long.


I love ZFS and I want to migrate all my data storage to it. The one thing that is holding me back is the inability to grow raid z with the demand. There is a pull request ongoing for a while now, but it is hard to tell when and if this feature will be available [1]. Anyone has any more insights if there is an ETA for this feature?

ZFS support on macOS has been barely beta-quality for at least five years. I wish it were actually cross-platform, but it really only works well on Linux and FreeBSD.
