Hello,
if I understand you correctly, you essentially don't need/want to use ZFS as a storage/file system, but used it anyway as a replacement for the missing hardware RAID controller in 4 of your machines. This way you aim to achieve the same configuration on all 8 machines despite different hardware. Correct? I am no expert here, but I guess this approach is not good. You may think about using classic linux software RAID (aka mdadm RAID) here. This is, according to this page: https://pve.proxmox.com/wiki/Software_RAID not officially supported. But I know it works, I did that some time ago on a test install. IIRC I even did that using the Proxmox installer, hidden somewhere under "Advanced options". If not, it is still possible to install a plain debian system on RAID+LVM and "convert" that to a proxmox node later: https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Stretch Andreas _______________________________________________ pve-user mailing list pve-user@pve.proxmox.com https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-user
