ganesha: store exports and export counter in RADOS

Allow the ganesha driver to store ganesha exports
and export counter as Ceph RADOS objects. This enables
highly available(HA) Ganesha servers in manila deployments
to store their config in a HA storage.

recommended to set this option even if the ganesha server is co-located
with the :term:`manila-share` service.
With NFS-Ganesha (v2.5.4 or later), Ceph (v12.2.2 or later), the driver (Queens
or later) can store NFS-Ganesha exports and export counter in Ceph RADOS
objects. This is useful for highly available NFS-Ganesha deployments to store
its configuration efficiently in an already available distributed storage
system. Set additional options in the NFS driver section to enable the driver
to do this.

The following ganesha library (See manila's ganesha library documentation for
more details) related options are set in the driver backend section above:
* ``ganesha_rados_store_enable`` to True for persisting Ganesha exports and
export counter in Ceph RADOS objects.
* ``ganesha_rados_store_pool_name`` to the Ceph RADOS pool that stores Ganesha
exports and export counter objects. If you want to use one of the backend
CephFS's RADOS pools, then using CephFS's data pool is preferred over using
its metadata pool.
Edit ``enabled_share_backends`` to point to the driver's backend section
using the section name, ``cephfnfs1``.

``%include <ganesha_export_dir>/INDEX.conf``
In versions 2.5.4 or later, Ganesha can store NFS client recovery data in
Ceph RADOS, and also read exports stored in Ceph RADOS. These features are
useful to make Ganesha server that has access to a Ceph (luminous or later)
storage backend, highly available. The Ganesha library class
`GaneshaNASHelper2` (in manila Queens or later) allows you to store Ganesha
exports directly in a shared storage, RADOS objects, by setting the following
manila config options in the driver section:
- `ganesha_rados_store_enable` = 'True' to persist Ganesha exports and export
counter in Ceph RADOS objects
- `ganesha_rados_store_pool_name` = name of the Ceph RADOS pool to store
Ganesha exports and export counter objects
- `ganesha_rados_export_index` = name of the Ceph RADOS object used to store
a list of export RADOS object URLs (defaults to 'ganesha-export-index')
Check out the `cephfs_driver` documentation for an example driver section
that uses these options.
To allow Ganesha to read from RADOS objects add the below code block in
ganesha's configuration file, substituting values per your setup.
.. code-block:: console
# To read exports from RADOS objects
RADOS_URLS {
ceph_conf = "/etc/ceph/ceph.conf";
userid = "admin";
}
# Replace with actual pool name, and export index object
%url rados://<ganesha_rados_store_pool_name>/<ganesha_rados_export_index>
# To store client recovery data in the same RADOS pool
NFSv4 {
RecoveryBackend = "rados_kv";
}
RADOS_KV {
ceph_conf = "/etc/ceph/ceph.conf";
userid = "admin";
# Replace with actual pool name
pool = <ganesha_rados_store_pool_name>;
}
For a fresh setup, make sure to create the Ganesha export index object as an
empty object before starting the Ganesha server.
