Keeping track of OSDs and their underlying storage devices/directories can be

The following storage selection settings are specific to Ceph and do not apply to other backends. All variables are key-value pairs represented as strings.
* `metadataDevice`: Name of a device to use for the metadata of OSDs on each node. Performance can be improved by using a low latency device (such as SSD or NVMe) as the metadata device, while other spinning platter (HDD) devices on a node are used to store data. Provisioning will fail if the user specifies a `metadataDevice` but that device is not used as a metadata device by Ceph. Notably, `ceph-volume` will not use a device of the same device class (HDD, SSD, NVMe) as OSD devices for metadata, resulting in this failure.
* `storeType`: `filestore` or `bluestore`, the underlying storage format to use for each OSD. The default is set dynamically to `bluestore` for devices, while `filestore` is the default for directories. Set this store type explicitly to override the default. Warning: Bluestore is **not** recommended for directories in production. Bluestore does not purge data from the directory and over time will grow without the ability to compact or shrink.
* `storeType`: `bluestore`, the underlying storage format to use for each OSD. The default is set dynamically to `bluestore` for devices and is the only supported format at this point.
* `databaseSizeMB`: The size in MB of a bluestore database. Include quotes around the size.
* `walSizeMB`: The size in MB of a bluestore write ahead log (WAL). Include quotes around the size.
* `journalSizeMB`: The size in MB of a filestore journal. Include quotes around the size.
* `osdsPerDevice`**: The number of OSDs to create on each device. High performance devices such as NVMe can handle running multiple OSDs. If desired, this can be overridden for each node and each device.
* `encryptedDevice`**: Encrypt OSD volumes using dmcrypt ("true" or "false"). By default this option is disabled. See [encryption](http://docs.ceph.com/docs/nautilus/ceph-volume/lvm/encryption/) for more information on encryption in Ceph.

* If `useAllDevices: false`, OSDs will only be created if `directories` or a `deviceFilter` are specified.

### Production Environments
For production environments it is required to have local storage devices attached to your nodes.
In this walkthrough, the requirement of local storage devices is relaxed so you can get a cluster up and running
as a "test" environment to experiment with Rook. A Ceph filestore OSD will be created in a `directory` instead
of requiring a device. For production environments, you will want to follow the example in `cluster.yaml` instead of
`cluster-test.yaml` in order to configure the devices instead of test directories. See the [Ceph examples](ceph-examples.md) for more details.

Now that the Rook operator is running we can create the Ceph cluster. For the cluster to survive reboots,
make sure you set the `dataDirHostPath` property that is valid for your hosts. For more settings, see the documentation on [configuring the cluster](ceph-cluster-crd.md).
Save the cluster spec as `cluster-test.yaml`:

Create the cluster:

kubectl create -f cluster-test.yaml
kubectl create -f cluster.yaml

Use `kubectl` to list pods in the `rook-ceph` namespace. You should be able to see the following pods once they are all running.
The number of osd pods will depend on the number of nodes in the cluster and the number of devices and directories configured.
If you did not modify the `cluster-test.yaml` above, it is expected that one OSD will be created per node.
