OpenEBS ZFS Host Prep

Run on the ZFS node before reconciling platform-openebs.

Upgrade the host ZFS stack and enable any required pool features before OpenEBS is installed. Backwards-incompatible pool features must be enabled only after confirming every host that may import the pool supports them.

Create the neutral parent dataset used by OpenEBS LocalPV ZFS. Workload-facing ZFS properties are declared in StorageClass parameters instead of being baked into parent datasets:

sudo zfs create -p ********

Verify the OpenEBS parent dataset:

zfs get recordsize,compression,dedup,mountpoint ********

Label the Kubernetes node:

kubectl label node <zfs-node-name> has-zfs=true --overwrite
