+RBD Namespaces
+~~~~~~~~~~~~~~
+
+Namespaces in the rados block device (RBD) layer can be used to have multiple
+Proxmox VE clusters using the same pool, but still be logically separated.
+Namespaces can be managed in the web UI in the 'Node -> Ceph -> Pools' panel.
+
+Alternatively, the `pveceph` or Ceph's `rbd` footnote:[https://docs.ceph.com/en/latest/man/8/rbd/]
+utility can be used too. To list all RBD namespaces of the pool `vmstore`, run the
+following command:
+[source, bash]
+----
+pveceph pool namespace ls vmstore
+----
+The result will be for example:
+[source, bash]
+----
+┌───────────┐
+│ Namespace │
+╞═══════════╡
+│ bar       │
+├───────────┤
+│ foo       │
+└───────────┘
+----
+
+To create a new RBD namespace `baz` in the pool `vmstore`, run:
+[source, bash]
+----
+pveceph pool namespace create vmstore baz --add-storage 1
+----
+The `--add-storage` parameter is optional an when set, will create a new
+storage configuration with the new namespace.
+
+To delete the `baz` RBD namespace in pool `vmstore`:
+[source, bash]
+----
+pveceph pool namespace destroy vmstore baz
+----
