Proxmox VE 9.1.1 – Windows Server / SQL Server issues

I don't think a single volume created with HW RAID can be repaired using ZFS Scrub. Is that configuration really okay...?

It seems to me like we're losing one of ZFS's major advantages...

> For replicated (mirror, raidz, or draid) devices, ZFS automatically repairs any damage discovered during the scrub.

I already know all the warnings regarding this configuration, but since in most cases the references mentioned are experiments on small home-lab, issues on cheap hardware and so on, I would like to cover this topic in the "enterprise servers" context.

The ZFS documentation got a nice summary with points why not to use ZFS on top of HW raid:
https://openzfs.github.io/openzfs-docs/Performance and Tuning/Hardware.html#hardware-raid-controllers

So its more a decision of reliability vs performance.

But thanks for the detailed benchmarks.

edit : If you are currently using ZFS and not using mirroring with hardware RAID, or if you have no plans to revert to hardware RAID, you can ignore this.

Maybe I explained myself badly, I said that I didn't create the raid1 from the controlled server, but I used proxmox to create the raid1zfs
