Creating shared file systems

Before being able to create a share, 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.

Note

This configuration automatically creates a cinder volume for every share. The cinder volumes are attached to share servers according to the definition of a share network.

Determine the configuration of the share server

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

    $ . admin-openrc.sh

  2. Create a default share type before running manila-share service:

    $ 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 |
+--------------------------------------+--------------------+------------+------------+-------------------------------------+-------------------------+

  3. Create a manila share server image to the Image service:

    $ glance image-create \
--copy-from http://tarballs.openstack.org/manila-image-elements/images/manila-service-image-master.qcow2 \
--name "manila-service-image" \
--disk-format qcow2 \
--container-format bare \
--visibility public --progress

| visibility       | public                               |
+------------------+--------------------------------------+

  4. List available networks in order to get id and subnets of the private network:

    $ neutron net-list
+--------------------------------------+---------+----------------------------------------------------+
| id                                   | name    | subnets                                            |
+--------------------------------------+---------+----------------------------------------------------+

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

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

    $ . demo-openrc.sh
    $ manila share-network-create --name demo-share-network1 \
--neutron-net-id PRIVATE_NETWORK_ID \
--neutron-subnet-id PRIVATE_NETWORK_SUBNET_ID

Create a share

  1. Create a NFS share using the share network:

    $ manila create NFS 1 --name demo-share1 --share-network demo-share-network1
+-----------------------------+--------------------------------------+
| Property                    | Value                                |

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

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

    $ manila list
+--------------------------------------+-------------+------+-------------+-----------+-----------+--------------------------------------+---------------------------------------------------------------+-----------------------------+-------------------+
| ID                                   | Name        | Size | Share Proto | Status    | Is Public | Share Type                           | Export location                                               | Host                        | Availability Zone |
+--------------------------------------+-------------+------+-------------+-----------+-----------+--------------------------------------+---------------------------------------------------------------+-----------------------------+-------------------+
| 5f8a0574-a95e-40ff-b898-09fd8d6a1fac | demo-share1 | 1    | NFS         | available | False     | 8a35da28-0f74-490d-afff-23664ecd4f01 | 10.254.0.6:/shares/share-0bfd69a1-27f0-4ef5-af17-7cd50bce6550 | storagenode@generic#GENERIC | nova              |
+--------------------------------------+-------------+------+-------------+-----------+-----------+--------------------------------------+---------------------------------------------------------------+-----------------------------+-------------------+

  3. Configure user access to the new share before attempting to mount it via the network:

    The image used for launching an instance and mounting a share must have the NFS packages provided by the distro. Example: The cirros image created at the image service section is not enough.

    Use an instance that is connected to the private network used to create the share-network.

    $ manila access-allow demo-share1 ip INSTANCE_PRIVATE_NETWORK_IP

Mount the share from an instance

  1. Create a folder where the mount will be placed:

    $ mkdir ~/test_folder

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

    $ mount -v 10.254.0.6:/shares/share-0bfd69a1-27f0-4ef5-af17-7cd50bce6550 ~/test_folder
