Thanks for the insight!

I may have to resort to using BTRFS for this host eventually if ZFS fails me. I do not expect a lot of duplication on a host, even if I have it, who cares I have 60 TB despite the raid 10 architecture. Having something with kernel support may be a better approach anyways.

It’s interesting to me that it struggles with raid 5 and 6 though. I would have expected that to be easy to provide.

BTRFS is a damn good option too. I’m happy to hear how easy it is to use. I haven’t used it(yet), I went with ZFS because of its flexible architecture. On a desktop level, BTRFS makes sense, but in a server? What is it like in a Hypervisor?

I’m working on standing up a Cloudstack host as a Hypervisor. Now, I want this host to be able to run 5 kubernetes VMs, so it needs to have quick access to the disks. Now, I do not have a RAID card, only an HBA. In such a scenario, I would typically use a RAID 10. But a ZFS Raid 10 outperforms an mdraid 10 anyways (in terms of writing, not necessarily reading). So that is what I’ve decided. It may not be a good idea, it may not even be feasible. But I’m heckin willing to give it a shot.

I’m actually jealous that you automatically have built in kernel support though. I am a little curious about BTRFS in terms of how(or if) it connects multiple disks, I’m simply uninformed.

ZFS Performance Sauce

Install Ubuntu 24.04 on ZFS RAID 10 - Github Repository

Edit: There are a few drawdowns to using ZFS, lousy docker performance being one that I’ve heard about. I’m curious how this will be affected if I have docker running inside a VM.

That’s fair. I chose ZFS because I’ve used it before. And understand it fairly well already. I know nothing about BTRFS, so perhaps you could educate me a little. I’m working on setting up a cloudstack host using ZFS RAID 10. Does BTRFS have a flexible architecture to where you could do something similar?

Edit: Perhaps you could also inform me of the speeds of BTRFS too. From what I understand, ZFS outperforms BTRFS in large datasets, but I don’t know where the cutoff is. I’ll let you know it would need to run 12 ea 10TB HDDs.

Try Root on ZFS.

If you run into an issue suddenly, you can restore to snapshot.

Uh… I don’t have a separate partition for /home. I have a separate zfs filesystem for it though. If I run into issues, I can restore from snapshot and not affect it.

Oh great… Look at the GNUguy. Here he is walking around all GNUde. He’s gonna come over demanding GNUggets of wisdom. And I’m just gonna say it, hell GNUpe, leave me alone to compile my thoughts in peace.

This comment was purely for fun, isn’t even funny, and frankly laughable. But it seemed like a good time for some word play. ✌️
