Hello Guys and Gals,

 

there was an exciting announcement from the OpenZFS team:

 

 

They have announced that this pull request:

https://github.com/openzfs/zfs/pull/12225

Will finally be implemented.

The pull request has been around for over two years.

 

iXsystems is sponsoring the implementation/further development.

 

Why this is exciting:

 

This feature will allow single storage discs to be added to an existing zfs pool.

With the current state of zfs, you'd have to add an additional pool which typically means that you'd have to double the number of discs. The expansion feature will come in handy for smaller pools and especially for many of us who like unraid for it's flexibility but still want the most reliable filesystem.

 

What do you guys think?

Anyone else as excited as me?

I saw the video a couple of days ago, but thanks for linking the pull request with more details, good that it looks like this is going to get finally done, nice feature mainly for hobbyists, which I assume covers most Unraid users, and makes zfs raidz a little more flexible.

A little? This is in my opinion the ONE change most homelabbers will have waited for if they want to expand as they go rather than moving, recreating pools, keeping money invested in drives that you wouldn't need storage-wise, etc...

 

I for one am ECSTATICb and cannot wait for this to land in unRAID. Glorious times, the single-most imporant feature I've been waiting for for sure for unRAID.

IMHO yes, you still cannot remove devices, change pool topology, etc.

Sure, those definitely are aspects that still need to be worked on, but this lifts ZFS from a very difficult to plan for FS for homelabbers who are attracted by unRAID's unique selling points to something that makes it workable where the remaining hurdles are a lot easier (and cheaper) to mitigate.

 

It most certainly is 80% of the way. Way more than a little if you ask me.

It's been merged:

I'm happy to announce that the long-awaited RAIDZ Expansion feature has officially landed in the OpenZFS master branch. This feature will need some soak time, but will be available in the OpenZFS 2.3 release, which is probably about a year out.

 

Hi

Ive got 2 servers Im rebuilding and I want to migrate to ZFS... but to do that without dataloss, Im going to need to use a method that requires using the RAIDZ expansion.

Any idea (roughly which quarter) we expect to see this functionality in Unraid?

 

thanks

 

is this supported yet on unraid? What versions have this feature?

It's not yet supported by zfs, last I heard it was planned for release later this year.
