hardware RAID; ZFS and replication

[0x2c4]

hi,

I am aiming to have replication for my VMs set on my proxmox cluster. Currently the file system is ext4 for VM drives and ZSF for boot drives, so I will be changing this to ZFS but...I realized that ZFS requires from me to set a software RAID...I have a hardware RAID on the drives (RAID1 on two boot drives and RAID 5 on 6 VM drives), In my opinion hardware RAID is much better than software, but maybe I am wrong?

What should I do to achieve the best result, should I disable the hardware RAID and set up software RAID with ZSF and then get replication, or is there a way to get replication with hardware RAID and maybe XFS....?

Thanks is advance.

Hi @0x2c4

Replication is allowed only for ZFS https://pve.proxmox.com/wiki/Storage_Replication

Do not forget for ZFS use only Enterprise SSD.

And there are another great discussions on same topic HW vs ZFS RAID including performance comparison.
