I really would like to give ZFs a try on proxmox. Reading several topics / forums about ZFS there is one thing I have noticed a couple of times. They advice to NEVER put your main OS on a ZFS volume.

If I choose ZFS during normal ISO-install, will proxmox/os be put on ZFS? And are there ways to avoid this? I'm looking for the best setup using 6 x SSD disks on a single node. With these disks I have several options:

- HW-raid 10 (LSI2208) with BBU
- Custom install of proxmox on SW-raid 10 with LVM

I like to give ZFS a try however, but I'm just wondering if the OS/proxmox will be on a ZFS volume if we install using the default ISO proxmox provides?

But if I choose ZFS from the installer, will the main OS be put on ZFS or not? Or will the installer create a separate partition for ZFS?

ZFS wants whole disks. if you only want to use ZFS as storage for guest disks, install using LVM/ext4, and use the remaining free disks after installation to setup a zpool yourself (see the admin guide and ZFS man pages for details). you can also have separate pools for OS/rpool and storage (again, by setting up the storage pool yourself AFTER installation).
