Phoronix: OpenZFS 2.2-rc2 Brings Linux 6.5 Compatibility Fixes, Other Bugs Addressed

Last month saw the first release candidate of OpenZFS 2.2 that introduces Linux container support, BLAKE3 checksums, and block cloning capabilities. Out this weekend is a second release candidate as OpenZFS 2.2 nears release...

I have a ZFS question I'm wondering if anyone can answer:

On Monday I had to reboot my PC where I noticed that one of the 3 HDDs in my RAIDZ went bad. Luckily, because it's ZFS, I could just pull the disk and keep on keepin on in a degraded state. What I'm wondering is "Can I replace my 4TB HDDs with 4TB SSDs, one SSD at a time, over the next three or four months?" I could care less about performance improvements, it's all about "Will ZFS let me do that and not eat my data?"

The moral of the story is to not buy those cheap-ass, janky Seagate Enterprise drives off of Amazon. It went out 3 months after the 5 year warranty expired.

yes you can replace one hdd with a ssd. you will also get a small performance boost every time you do that.

EDIT: please make sure you use at least ashift=12 on that array. due to wear levelling thats even more important with ssds than hdds

I did that on the HDD array just to be future forward, anticipating a scenario like this happening

❯zpool get all | grep ashift
zeta ashift 12 local
zpcachyos ashift 12 local

zeta is the pool in question

I’m confused. The change log says compatible with 3.10 - 6.3 kernels but the title says this rc brings 6.5 compatibility fixes. If I understand it correctly the support is a work in progress and not completed.

What does

"introduces Linux container support"

Mean?

I'm running docker with the data saved in zfs already

It's pretty rude to hijack threads like that. Watch out that 4TB might differ in size between drives, more than one person has bought new drives only to find that they can't fit all the data of the old ones.

support for namespaces and overlayfs:

Posting the first ZFS related comment or question in a ZFS thread isn't hijacking a thread. That's literally being on topic and the opposite of hijacking a thread. With that said:

It's rude to falsely accuse people of things they didn't do followed by horribly mansplaining to them about drive sizes. For future reference, if you're going to mansplain you can at least mentioned the key information of 1000/1024, kib/kb, which is why 4TB on the box can result in 3.68TB in the OS.

Technically speaking, your false accusation of calling me a rude thread-jacker while being a mansplainer was hijacking the thread.

Now, when I posted ATi macro pictures in a random AMD CPU thread, that was thread hijacking.

What's funny is I'm probably the biggest thread hijacker and off-topic poster on Phoronix. This wasn't one of those times. I can assure you that you'd know if it was.

I'd like to thank you for the good laugh I'm having from this interaction. The irony of someone accusing someone else of being a thread hijacker when the accuser is the actual thread hijacker and caused the thread to go off-topic about being off-topic is very, very funny to me.

Shit. I just mansplained a mansplainer. Is that like a double negative where one cancels the other out? I can only hope.

Asking for random support in a news-thread is though, but you do you.

That isn't the issue though, if it was it would be the same issue for SSD and HDD and cancel out anyway.
