From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Finally! #15022, it's been a long time coming...

I literally just got bigger drives for my array last week. So happy I put it off.

[–] cyberpunk007@lemmy.ca 2 points 2 weeks ago

So did I, yesterday, but I still think I have to rebuild because I'm reducing disk quantities :(

Also, note that doesn't increase the stripe size for old data; it's just for future writes.

But you could copy the old data to a new location and it would take advantage of the new stripe size.

How does it work before this release?

[–] 7fb2adfb45bafcc01c80@lemmy.world 5 points 2 weeks ago (1 children)

It used to be that you couldn't grow the pool, so you needed all of your drives up-front.

Now you can start with four drives and slowly grow over time to whatever your target goal is. It's much more friendly for home labs/tight budgets.

That's good to hear. I assume people saying "ZFS" are usually referring to this OpenZFS (and usually not Oracle ZFS)?

[–] Atemu@lemmy.ml 2 points 2 weeks ago

Oracle ZFS is so obscure by now that it's irrelevant.

As usual with Oracle products, it's just a means to squeeze poorly led companies.

I like JSON output. Will make my monitoring jobs less fragile.

[–] Dragonish@lemmy.dbzer0.com 8 points 2 weeks ago

Super excited to see the expansion functionality released!

Will 1023 byte filename break software? Most only support 256.

Wasn't raidz expansion already in a tagged version or did I miss remember?
