+It is possible to run an arbitrary list of commands against the cluster after
+deployment by setting the ``cephadm_commands_pre`` and ``cephadm_commands_post``
+variables. Each should be a list of commands to pass to ``cephadm shell --
+ceph``. For example:
 
 .. code:: yaml
 
    # A list of commands to pass to cephadm shell -- ceph. See stackhpc.cephadm.commands
    # for format.
-   cephadm_commands:
+   cephadm_commands_pre:
     # Configure Prometheus exporter to listen on a specific interface. The default
     # is to listen on all interfaces.
     - "config set mgr mgr/prometheus/server_addr 10.0.0.1"
 
+Both variables have the same format, however commands in the
+``cephadm_commands_pre`` list are executed before the rest of the Ceph
+post-deployment configuration is applied. Commands in the
+``cephadm_commands_post`` list are executed after the rest of the Ceph
+post-deployment configuration is applied.

 1. ``source kayobe-env --environment ci-aio``
 2. Run ``kayobe overcloud host configure``
 3. Run ``kayobe overcloud service deploy``
+
+
+Manila
+======
+The Multinode environment supports Manila with the CephFS native backend, but it
+is not enabled by default. To enable it, set the following in
+``/etc/kayobe/environments/ci-multinode/kolla.yml``:
+
+.. code-block:: yaml
+
+      kolla_enable_manila: true
+      kolla_enable_manila_backend_cephfs: true
+
+And re-run ``kayobe overcloud service deploy`` if you are working on an existing
+deployment.
+
+To test it, you will need two virtual machines. Cirros does not support the Ceph
+kernel client, so you will need to use a different image. Any regular Linux
+distribution should work. As an example, we will use Ubuntu 20.04.
+
+Download the image locally:
+
+.. code-block:: bash
+
+      wget http://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64.img
+
+Upload the image to Glance:
+
+.. code-block:: bash
+
+      openstack image create --container-format bare --disk-format qcow2 --file focal-server-cloudimg-amd64.img Ubuntu-20.04 --progress
+
+Create a keypair:
+
+.. code-block:: bash
+
+      openstack keypair create --private-key ~/.ssh/id_rsa id_rsa
+
+Create two virtual machines from the image:
+
+.. code-block:: bash
+
+      openstack server create --flavor m1.small --image Ubuntu-20.04 --key-name id_rsa --network admin-tenant ubuntu-client-1
+      openstack server create --flavor m1.small --image Ubuntu-20.04 --key-name id_rsa --network admin-tenant ubuntu-client-2
+
+Wait until the instances are active. It is worth noting that this process can
+take a while, especially if the overcloud is deployed to virtual machines. You
+can monitor the progress with the following command:
+
+.. code-block:: bash
+
+      watch openstack server list
+
+Once they are active, create two floating IPs:
+
+.. code-block:: bash
+
+      openstack floating ip create external
+      openstack floating ip create external
+
+Associate the floating IPs to the instances:
+
+.. code-block:: bash
+
+      openstack server add floating ip ubuntu-client-1 <floating-ip-1>
+      openstack server add floating ip ubuntu-client-2 <floating-ip-2>
+
+
+Then SSH into each instance and install the Ceph client:
+
+.. code-block:: bash
+
+      sudo apt update
+      sudo apt install -y ceph-common
+
+
+Back on the host, install the Manila client:
+
+.. code-block:: bash
+
+      sudo dnf install -y python-manilaclient
+
+Then create a share type and share:
+
+.. code-block:: bash
+
+      manila type-create cephfs-type false --is_public true
+      manila type-key cephfs-type set vendor_name=Ceph storage_protocol=CEPHFS
+      manila create --name test-share --share-type cephfs-type CephFS 2
+
+Wait until the share is available:
+
+.. code-block:: bash
+
+      manila list
+
+Then allow access to the shares to two users:
+
+.. code-block:: bash
+
+      manila access-allow test-share cephx alice
+      manila access-allow test-share cephx bob
+
+Show the access list to make sure the state of both entries is ``active`` and
+take note of the access keys:
+
+.. code-block:: bash
+
+      manila access-list test-share
+
+And take note of the path to the share:
+
+.. code-block:: bash
+
+      manila share-export-location-list test-share
+
+SSH into the first instance, create a directory for the share, and mount it:
+
+.. code-block:: bash
+
+      mkdir testdir
+      sudo mount -t ceph {path} -o name=alice,secret='{access_key}' testdir
+
+Where the path is the path to the share from the previous step, and the secret
+is the access key for the user alice.
+
+Then create a file in the share:
+
+.. code-block:: bash
+
+      sudo touch testdir/testfile
+
+SSH into the second instance, create a directory for the share, and mount it:
+
+.. code-block:: bash
+
+      mkdir testdir
+      sudo mount -t ceph {path} -o name=bob,secret='{access_key}' testdir
+
+Where the path is the same as before, and the secret is the access key for the
+user bob.
+
+Then check that the file created in the first instance is visible in the second
+instance:
+
+.. code-block:: bash
+
+      ls testdir
+
+If it shows the test file then the share is working correctly.
