Creating shares with Shared File Systems Option 1 (DHSS = False)

Create a share type

Disable DHSS (driver_handles_share_servers) before creating a share using the LVM driver.

1. Source the admin credentials to gain access to admin-only CLI commands:

   $ . admin-openrc

2. Create a default share type with DHSS disabled. A default share type will allow you to create shares with this driver, without having to specify the share type explicitly during share creation.

   $ manila type-create default_share_type False
   +----------------------+--------------------------------------+
   | Property             | Value                                |
   +----------------------+--------------------------------------+
   | required_extra_specs | driver_handles_share_servers : False |
   | Name                 | default_share_type                   |
   | Visibility           | public                               |
   | is_default           | -                                    |
   | ID                   | 3df065c8-6ca4-4b80-a5cb-e633c0439097 |
   | optional_extra_specs | snapshot_support : True              |
   +----------------------+--------------------------------------+

   Set this default share type in manila.conf under the [DEFAULT] section and restart the manila-api service before proceeding. Unless you do so, the default share type will not be effective.

   Note

   Creating and configuring a default share type is optional. If you wish to use the shared file system service with a variety of share types, where each share creation request could specify a type, please refer to the Share types usage documentation here <http://docs.openstack.org/admin-guide/shared-file-systems-share-types.html>_.

Create a share

1. Source the demo credentials to perform the following steps as a non-administrative project:

   $ . demo-openrc

2. Create an NFS share. Since a default share type has been created and configured, it need not be specified in the request.

   $ manila create NFS 1 --name share1

   +-----------------------------+--------------------------------------+

3. After some time, the share status should change from creating to available:

   $ manila list
   +--------------------------------------+--------+------+-------------+-----------+-----------+--------------------+-----------------------------+-------------------+
   | ID                                   | Name   | Size | Share Proto | Status    | Is Public | Share Type Name    | Host                        | Availability Zone |
   +--------------------------------------+--------+------+-------------+-----------+-----------+--------------------+-----------------------------+-------------------+
   | 55c401b3-3112-4294-aa9f-3cc355a4e361 | share1 | 1    | NFS         | available | False     | default_share_type | storage@lvm#lvm-single-pool | nova              |
   +--------------------------------------+--------+------+-------------+-----------+-----------+--------------------+-----------------------------+-------------------+

4. Determine export IP address of the share:

   $ manila show share1
   +-----------------------------+------------------------------------------------------------------------------------+
   | Property                    | Value                                                                              |
   +-----------------------------+------------------------------------------------------------------------------------+
   | status                      | available                                                                          |

Allow access to the share

1. Configure access to the new share before attempting to mount it via the network. The compute instance (whose IP address is referenced by the INSTANCE_IP below) must have network connectivity to the network specified in the share network.

   $ manila access-allow share1 ip INSTANCE_IP
   +--------------+--------------------------------------+
   | Property     | Value                                |

   | share_id     | 55c401b3-3112-4294-aa9f-3cc355a4e361 |
   | access_type  | ip                                   |
   | access_to    | 10.0.0.46                            |
   | access_level | rw                                   |
   | state        | new                                  |
   | id           | f88eab01-7197-44bf-ad0f-d6ca6f99fc96 |
   +--------------+--------------------------------------+

Mount the share on a compute instance

1. Log into your compute instance and create a folder where the mount will be placed:

   $ mkdir ~/test_folder

2. Mount the NFS share in the compute instance using the export location of the share:

   # mount -vt nfs 10.0.0.41:/var/lib/manila/mnt/share-8e13a98f-c310-41df-ac90-fc8bce4910b8 ~/test_folder
