Yeah maybe my machines are cursed

It doesn’t share well. Anytime anything IO heavy happens the system completely locks up.

That doesn’t happen on other systems

Is your machine part of a cluster by chance? Of so, when you do a VM transfer what performance do you see?

I though was then removed later as there was a disagreement between Linus and the bcachefs dev

I have been trying to get ZFS working well for months. Also I am not the only one having issues as I have seen lots of other posts about similar problems.

Yeah it sounds like I don’t have enough ram.

Btrfs Raid 5 and raid 6 are unstable and dangerous

Bcachefs is cool but it is way to new and isn’t even part of the kernel as of yet.

For raid?

How much ram and what is the drive size?

I suspect this also could be an issue with SSDs. I have seen a lot a posts around describing similar performance on SSDs.

Maybe I am CPU bottlenecked. I have a mix of i5-8500 and i7-6700k

The drives are a mix but I get almost the same performance across machines

What’s up is ZFS. It is solid but the architecture is very dated at this point.

There are about a hundred different settings I could try to change but at some point it is easier to go btrfs where it works out of the box.

Was that less than 2 years ago? Were you using kernel 5.15 or newer?

There are IPv4 to IPv6 translation layers potentially. They shouldn’t cause issues but it untrue that IPv4 and IPv6 don’t interact.

Why?

I already take backups but I’m curious if you have had any serious issues

It is stable with raid 0,1 and 10.

Raid 5 and 6 are dangerous

Proxmox only supports btrfs or ZFS for raid

Or at least that’s what I thought

I have never heard of anyone getting those speeds without dedicated high end hardware

Also the write will always be your bottleneck.

Btrfs Raid 10 reportedly is stable

Likely not possible thanks to “enhanced security”

It has a TPM and restricted boot so probably no Linux
