Create NFS Ganesha Cluster
--------------------------

This creates a common recovery pool for all NFS Ganesha daemons, new user based on
``cluster_id``, and a common NFS Ganesha config RADOS object.

Ganesha daemons on the cluster (should you want to have more than one NFS Ganesha
daemon running per node). For example, the following placement string means

+"deploy NFS Ganesha daemons on nodes host1 and host2" (one daemon per host)::

When using cephadm orchestration, these commands check service status:

Updating an NFS Cluster
-----------------------
-In order to modify cluster parameters (like the port or placement), you need to
-use the orchestrator interface to update the NFS service spec. The safest way to do
-that is to export the current spec, modify it, and then re-apply it. For example,

For more information about the NFS service spec, see :ref:`deploy-cephadm-nfs-ganesha`.
List NFS Ganesha Clusters
-------------------------
-.. code:: bash
+.. prompt:: bash #
- $ ceph nfs cluster ls
+ ceph nfs cluster ls
This lists deployed clusters.
Set Customized NFS Ganesha Configuration
----------------------------------------
-.. code:: bash
+.. prompt:: bash #
- $ ceph nfs cluster config set <cluster_id> -i <config_file>
+ ceph nfs cluster config set <cluster_id> -i <config_file>
With this the nfs cluster will use the specified config and it will have
precedence over default config blocks.
Example use cases include:
-#. Changing log level. The logging level can be adjusted with the following config
- fragment::

- `auth get-or-create`::
+ `auth get-or-create`:
- # ceph auth get-or-create client.<user_id> mon 'allow r' osd 'allow rw pool=.nfs namespace=<nfs_cluster_name>, allow rw tag cephfs data=<fs_name>' mds 'allow rw path=<export_path>'

-----------------------------------------
-.. code:: bash
+.. prompt:: bash #
- $ ceph nfs cluster config get <cluster_id>

This will output the user defined configuration (if any).
Reset NFS Ganesha Configuration
-------------------------------
-.. code:: bash
+.. prompt:: bash #
- $ ceph nfs cluster config reset <cluster_id>
+ ceph nfs cluster config reset <cluster_id>
This removes the user defined configuration.
Create CephFS Export
--------------------
-.. code:: bash
+.. prompt:: bash #
- $ ceph nfs export create cephfs --cluster-id <cluster_id> --pseudo-path <pseudo_path> --fsname <fsname> [--readonly] [--path=/path/in/cephfs] [--client_addr <value>...] [--squash <value>] [--sectype <value>...] [--cmount_path <value>]

This creates export RADOS objects containing the export block, where
``<path>`` is the path within cephfs. Valid path should be given and default
path is '/'. It need not be unique. Subvolume path can be fetched using:
-.. code::
+.. prompt:: bash #
