HA Best Practice

I only have 1 local NVMe on each node.
Note that this does NOT give you any redundancy. Neither with LVM not with ZFS.

ZFS has self-healing features which requires some redundancy to be present. The usual way is to create mirrors - and for specific tasks contructs called RaidZ.

Redundancy is not a requirement for ZFS in itself. But is is recommended ;-)
