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:
enable_cinder: "yes"
enable_ceph: "yes"Enable Manila in /etc/kolla/globals.yml:
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:
[generic]
service_instance_flavor_id = 2Verify operation
Verify operation of the Shared File Systems service. List service components to verify successful launch of each process:

+------------------+----------------+------+---------+-------+----------------------------+-----------------+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:
# manila type-create default_share_type True

+--------------------------------------+--------------------+------------+------------+-------------------------------------+-------------------------+Create a manila share server image to the Image service:
# wget http://tarballs.openstack.org/manila-image-elements/images/manila-service-image-master.qcow2
