Without specifying a device, rook's osd-prepare job scans the node for all devices that can be retrieved with command lsflk --all.

| - `clusters`: Contains the two `AttachedCluster` objects created earlier, indicating that the distributedstorage plugin will be installed on these two clusters. | ||
| - `plugin`: The `distributedStorage` indicates the configuration of a distributedstorage plugin. `dataDirHostPath` defines the directory in which the rook-ceph cluster will save the cluster configuration. `monitor` and `manager` provide configuration for the mon and mgr components of ceph. For more configuration options, please refer to the [Fleet API](https://kurator.dev/docs/references/fleet-api/). | ||
| - In addition to the configuration fields mentioned above, kurator also provides `storage.devices` field that allows you to specify the use of disks mounted in a specific directory such as `sda` in the cluster. And `storage.nodes` field that allows you to specify the use of storage resources on specific nodes. For more configuration options, please refer to the [Fleet API](https://kurator.dev/docs/references/fleet-api/). |

I am not sure what you mean by sda in the cluster? Is it set in the example?

sda is a device mounted on /dev/sda. if a specific mount path is specified, rook will check the specified path on all nodes in the cluster for the presence of storage resources that comply with requirements.

| Let's delve into the `spec` section of the above Fleet: | ||
|
|
||
| - `clusters`: Contains the two `AttachedCluster` objects created earlier, indicating that the distributedstorage plugin will be installed on these two clusters. |
| There are a few things to note in the above block storage class configuration: | ||
|
|
||
| - provisioner is configured in the format (operator-namespace).rbd.csi.ceph.com. Change "rook-ceph" provisioner prefix to match the operator namespace if needed. | ||
| - `parametes.clusterID` is the namespace where the rook cluster is running. |

In the documentation for rook, it is mentioned that the clusterID is the namespace where the rook cluster is running.
