Hey,
I've not long setup 2 OVH (SoYouStart) Servers myself, with Fully
encrypted ZFS with Proxmox.
I think the best approach personally is to reinstall either using
proxmox installer ISO via KVM. Then you can install with ZFS as you
want. Then you can setup RAIDZ1 etc, allowing for one disk failure.
If you want ZFS and full disk encryption, then its a much longer process
but doable. See links below.
Is there a reason you didn't use the KVM and install from ISO to start
with?
I followed these two guides: (tweaked bits here and there though)

Don't have experience with OVH, but depending on the situation, it might be
possible to "transfer" the existing OS installation to a ZFS backed setup.
To do so, it will be required to have an additional hdd, partition it,
create a ZFS pool on it with proper datasets (rpool/ROOT/pve-1 etc..), set
the appropriate zfs options for each dataset (you can use an existing root
on zfs installation as a reference) and rsync the existing PVE (lvm)
installation onto it. Then chroot into the zfs installation and make the
required changes in grub, initramfs,fstab etc etc, finally boot from the
system from the zfs disk. It will require some effort, but should be
doable.
What are the benefits? Unless you want to benefit from the zfs snapshots
for rolling back your system after an unwanted system update, I don't see
any.
Is it worth it? Don't think so, especially since this is a backup system.
Since you've managed to create a zfs pool for storing your VMs (pve-zsync
target), that should be enough in my opinion.

Subject: Proxmox 5 to root on ZFS
Hi,
I have a new dedicated server on OVH with two sets of SSD and SATA
drives (4 in total). Template from OVH only installs Proxmox 5 without
ZFS on a LVM soft RAID1. I have used this tool to create a ZFS pool:
https://github.com/extremeshok/xshok-proxmox
But I´m wondering if It would be worth the effort to try move the OS
too to ZFS. What are the benefits? I am using this machine for disaster
recovery VM (pve-zsync) and run backups.
If It is worth it, any advice on how to do it? I can´t find a proper
procedure, I just have a rescue system from OVH (not possible to use
specific ISO or KVM)
Thanks!
Miguel
