# 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:

```sh
sudo zfs create -p ********
```

Verify the OpenEBS parent dataset:

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

Label the Kubernetes node:

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