ZFS on Linux - Proxmox VE
https://pve.proxmox.com/wiki/ZFS_on_LinuxWhen you install using the Proxmox VE installer, you can choose ZFS for the root file system. You need to select the RAID type at installation time: The installer automatically partitions the disks, creates a ZFS pool called rpool, and installs the root file system on the ZFS subvolume rpool/ROOT/pve-1.
