Have you try to use that kernel: https://github.com/KrzysztofHajdamowicz/pve-kernel/releases ?

Can it be used with nvmeof over rdma (with multipath) to maximize iops performance? So I am just connecting the same nvmeof target on 2 or 3 proxmox nodes and set normal LVM?

New kernel from proxmox repo is working fine: 6.14.8-2-pve

Just use kernel: https://github.com/KrzysztofHajdamowicz/pve-kernel/releases

I have exactly that kind of issue.

Kernel is broken with Mellanox 100G Connectx-5 VF on Proxmox 9.0 Beta. That card works fine only on Host without VF, so vfio-pci is broken in that release I think. kvm: -device vfio-pci,host=0000:81:00.1,id=hostpci0,bus=ich9-pcie-port-1,addr=0x0: vfio 0000:81:00.1: error getting device from...

Patch upgraded to PVE 9.0 Beta 1: https://github.com/dominiaz/iothread-vq-mapping

Yes, it should work with ZFS. You can test it.

I made patch that enables advanced iothread-vq-mapping for virtio-blk devices in Proxmox VE 8.4. https://github.com/dominiaz/iothread-vq-mapping Just add eg. iothread_vq_mapping=8 to your virtio drive configuration.

You have bad point of view. I have fast storage with 8 mln IOPS, so normal 150-200k IOPS per VM (with actual 1x iothread) is very, very bad. If you want sell 200k IOPS or 1mln IOPS then you sell it in fair price. You can always set 1-64 Iothreads per VM, but we need to have a choice.

Drop ZFS and use Xiraid Opus for best iops performance.

Hey, Unfortunately SupremeRAID SE (Linux Driver 1.7.0 Beta) is not comptabile with Proxmox VE 8.2 (Kernel 6.8). I made Raid5 with 4x Micron 7400 Pro 1,92 TB and Raid0 with Seagate FireCuda 530. I`ve tried Graid with GPU RTX A2000 and RTX 3060. Everything works smooth - read/write/fio on...

I will be happy to start testing on new topic. My hardware is 4x Micron 7400 1,92TB, 2x Micron 7400 3,84 TB and 2x DL380G10 connected by Mellanox card with 100G RDMA.

I want to compare iops on 2 local nvme vs raidz1 zfs 2.3 direct i/o mirror on thiese nvme.

Very interesting. How many iops did you get on Guest on node1 and node3?
