Hi

I'm installing Proxmox on a 128GB SSD but I only require 32GB and want to use some of the additional space for redundancy in case of data corruption or configuration error.

I was hoping that I can use ZFS's Snapshots, Copy-on-write clone or RAIDZ-1 to accomplish some of this or even LVM.
It should require as little human intervention as possible.

What would be my best option in this regard without a significant system impact?

thx
 
Thanks

I set the copies=2 in the ZFS configuration to protect against bit flips and data rot.
I am also making snapshots of my VMs after any configuration changes as restore points.

Together they sould provide sufficient redundancy for my requirements.

One last thing, AFAIR ZFS will honor such settings only for newly written data after the settings has been applied.
