Shared File Systems

Create the service image

Note

In typical deployments, you should create an instance from an image that supports network file systems such as NFS/CIFS to evaluate the Shared File Systems service. This guide should use the CirrOS image for instances to reduce resource requirements for evaluation. However, the CirrOS image lacks support for network file systems. For evaluation of the Shared File Systems service, this guide creates a regular instance using the manila-share-service image because it supports network file systems and using the manila-service-flavor that limits resource consumption by the instance to 256 MB memory on the compute node.

1. Download the source image of the share server:

   $ wget http://tarballs.openstack.org/manila-image-elements/images/manila-service-image-master.qcow2

2. Add the image to the Image service:

   # openstack image create "manila-service-image" \
   --file manila-service-image-master.qcow2 \
   --disk-format qcow2 \
   --container-format bare \
   --public

3. Create a new flavor to support the service image:

   # openstack flavor create manila-service-flavor --id 100 --ram 256 --disk 0 --vcpus 1
   +----------------------------+-----------------------+
   | Field                      | Value                 |
   +----------------------------+-----------------------+
   | OS-FLV-DISABLED:disabled   | False                 |
   | OS-FLV-EXT-DATA:ephemeral  | 0                     |
   | disk                       | 0                     |
   | id                         | 100                   |
   | name                       | manila-service-flavor |
   | os-flavor-access:is_public | True                  |
   | ram                        | 256                   |
   | rxtx_factor                | 1.0                   |
   | swap                       |                       |
   | vcpus                      | 1                     |
   +----------------------------+-----------------------+

   Note

   Flavor is image specific and may differ from image to image.

Launch an instance of the service image

Note

This section uses manila-service-image image as an instance for mounting shares.

1. Launch an instance using the manila-service-image and manila-service-flavor.
2. Log into the instance using manila as the username and password.

Create a share

Create a share for the Shared File Systems service option that you chose in manila-storage.
