Manila in Kolla
===============
Overview
--------
Currently, Kolla can deploy following manila services:
* manila-api
* manila-scheduler
* manila-share
The OpenStack Shared File Systems service (Manila) provides file storage to a
virtual machine. The Shared File Systems service provides an infrastructure
for managing and provisioning of file shares. The service also enables
management of share types as well as share snapshots if a driver supports
them.
Important
---------
For simplicity, this guide describes configuring the Shared File Systems
service to use the ``generic`` back end with the driver handles share
server mode (DHSS) enabled that uses Compute (nova), Networking (neutron)
and Block storage (cinder) services.
Networking service configuration requires the capability of networks being
attached to a public router in order to create shared networks.
Before you proceed, ensure that Compute, Networking and Block storage
services are properly working.
Preparation and Deployment
--------------------------
Cinder and Ceph are required, enable it in /etc/kolla/globals.yml:
.. code-block:: console
enable_cinder: "yes"
enable_ceph: "yes"
Enable Manila in /etc/kolla/globals.yml:
.. code-block:: console
enable_manila: "yes"
By default Manila uses instance flavor id 100 for its file systems. For
Manila to work, either create a new nova flavor with id 100 (using "nova
flavor-create") or change service_instance_flavor_id to use one of the
default nova flavor ids.
Ex: service_instance_flavor_id = 2 to use nova default flavor m1.small.
Create or modify the file /etc/kolla/config/manila.conf and add the contents:
.. code-block:: console
[generic]
service_instance_flavor_id = 2
Verify operation
----------------
Verify operation of the Shared File Systems service. List service components
to verify successful launch of each process:
.. code-block:: console
# manila service-list
+------------------+----------------+------+---------+-------+----------------------------+-----------------+
| Binary | Host | Zone | Status | State | Updated_at | Disabled Reason |
+------------------+----------------+------+---------+-------+----------------------------+-----------------+
| manila-scheduler | controller | nova | enabled | up | 2014-10-18T01:30:54.000000 | None |
| manila-share | share1@generic | nova | enabled | up | 2014-10-18T01:30:57.000000 | None |
+------------------+----------------+------+---------+-------+----------------------------+-----------------+
Launch an Instance
------------------
Before being able to create a share, the manila with the generic driver and
the DHSS mode enabled requires the definition of at least an image,
a network and a share-network for being used to create a share server.
For that back end configuration, the share server is an instance where
NFS/CIFS shares are served.
Determine the configuration of the share server
-----------------------------------------------
Create a default share type before running manila-share service:
.. code-block:: console
# manila type-create default_share_type True
+--------------------------------------+--------------------+------------+------------+-------------------------------------+-------------------------+
| ID | Name | Visibility | is_default | required_extra_specs | optional_extra_specs |
+--------------------------------------+--------------------+------------+------------+-------------------------------------+-------------------------+
| 8a35da28-0f74-490d-afff-23664ecd4f01 | default_share_type | public | - | driver_handles_share_servers : True | snapshot_support : True |
+--------------------------------------+--------------------+------------+------------+-------------------------------------+-------------------------+
Create a manila share server image to the Image service:
.. code-block:: console
# wget http://tarballs.openstack.org/manila-image-elements/images/manila-service-image-master.qcow2
# glance image-create --name "manila-service-image" \
--file manila-service-image-master.qcow2 \
--disk-format qcow2 --container-format bare \
--visibility public --progress

Create a folder where the mount will be placed:
.. code-block:: console
# mkdir ~/test_folder
Mount the NFS share in the instance using the export location of the share:
.. code-block:: console
# mount -v 10.254.0.3:/shares/share-422dc546-8f37-472b-ac3c-d23fe410d1b6 ~/test_folder
