Share basic operations

General concepts

To create a file share, and access it, the following general concepts
are prerequisite knowledge:

  1. To create a share, use manila create command and specify the required
    arguments: the size of the share and the shared file system protocol.
    NFS, CIFS, GlusterFS,
    HDFS, CephFS or MAPRFS share file
    system protocols are supported.
  2. You can also optionally specify the share network and the share
    type.
  3. After the share becomes available, use the manila show command to
    get the share export locations.
  4. After getting the share export locations, you can create an access rule <access_to_share> for the share,
    mount it and work with files on the remote file system.

There are big number of the share drivers created by different
vendors in the Shared File Systems service. As a Python class, each
share driver can be set for the back end <shared_file_systems_multi_backend> and
run in the back end to manage the share operations.

Initially there are two driver modes for the back ends:

  • no share servers mode
  • share servers mode

Each share driver supports one or two of possible back end modes that
can be configured in the manila.conf file. The
configuration option driver_handles_share_servers in the
manila.conf file sets the share servers mode or no share
servers mode, and defines the driver mode for share storage lifecycle
management:

ModeConfig option

Description

no share serversdriver_handles_share_servers = FalseAn administrator rather than a share driver manages the bare metal
storage with some net interface instead of the presence of the share
servers.
share serversdriver_handles_share_servers = TrueThe share driver creates the share server and manages, or handles,
the share server life cycle.

It is the share types <shared_file_systems_share_types>
which have the extra specifications that help scheduler to filter back
ends and choose the appropriate back end for the user that requested to
create a share. The required extra boolean specification for each share
type is driver_handles_share_servers. As an administrator,
you can create the share types with the specifications you need. For
details of managing the share types and configuration the back ends, see
shared_file_systems_share_types and shared_file_systems_multi_backend documentation.

You can create a share in two described above modes:

  • in a no share servers mode without specifying the share network and
    specifying the share type with
    driver_handles_share_servers = False parameter. See
    subsection create_share_in_no_share_server_mode.
  • in a share servers mode with specifying the share network and the
    share type with driver_handles_share_servers = True
    parameter. See subsection create_share_in_share_server_mode.

Create a share in no share
servers mode

To create a file share in no share servers mode, you need to:

  1. To create a share, use manila create command and specify the required
    arguments: the size of the share and the shared file system protocol.
    NFS, CIFS, GlusterFS,
    HDFS, CephFS or MAPRFS share file
    system protocols are supported.
  2. You should specify the share type <shared_file_systems_share_types>
    with driver_handles_share_servers = False extra
    specification.
  3. You must not specify the share network because no share
    servers are created. In this mode the Shared File Systems service
    expects that administrator has some bare metal storage with some net
    interface.
  4. The manila create command creates a share. This
    command does the following things:

    • The manila-scheduler <shared_file_systems_scheduling>
      service will find the back end with
      driver_handles_share_servers = False mode due to filtering
      the extra specifications of the share type.
    • The share is created using the storage that is specified in the
      found back end.
  5. After the share becomes available, use the manila show command to
    get the share export locations.

In the example to create a share, the created already share type
named my_type with
driver_handles_share_servers = False extra specification is
used.

Check share types that exist, run:

$ manila type-list
+------+---------+------------+------------+--------------------------------------+-------------------------+
| ID   | Name    | visibility | is_default | required_extra_specs                 | optional_extra_specs    |
+------+---------+------------+------------+--------------------------------------+-------------------------+
| %ID% | my_type | public     | -          | driver_handles_share_servers : False | snapshot_support : True |
+------+---------+------------+------------+--------------------------------------+-------------------------+

Create a private share with my_type share type, NFS
shared file system protocol, and size 1 GB:

Create a share in share
servers mode

To create a file share in share servers mode, you need to:

  1. To create a share, use manila create command and specify the required
    arguments: the size of the share and the shared file system protocol.
    NFS, CIFS, GlusterFS,
    HDFS, CephFS or MAPRFS share file
    system protocols are supported.
  2. You should specify the share type <shared_file_systems_share_types>
    with driver_handles_share_servers = True extra
    specification.
  3. You should specify the share network <shared_file_systems_share_networks>.
  4. The manila create command creates a share. This
    command does the following things:

  5. After the share becomes available, use the manila show command to
    get the share export location.

In the example to create a share, the default share type and the
already existing share network are used.

Note

There is no default share type just after you started manila as the
administrator. See shared_file_systems_share_types to create the default
share type. To create a share network, use shared_file_systems_share_networks.

Check share types that exist, run:

$ manila type-list
+------+---------+------------+------------+--------------------------------------+-------------------------+
| ID   | Name    | visibility | is_default | required_extra_specs                 | optional_extra_specs    |
+------+---------+------------+------------+--------------------------------------+-------------------------+
| %id% | default | public     | YES        | driver_handles_share_servers : True  | snapshot_support : True |
+------+---------+------------+------------+--------------------------------------+-------------------------+

Check share networks that exist, run:

$ manila share-network-list
+--------------------------------------+--------------+
| id                                   | name         |

Create a public share with my_share_net network,
default share type, NFS shared file system protocol, and
size 1 GB:

$ manila create nfs 1 \
    --name "Share2" \
    --description "My second share" \
    --share-type default \
    --share-network my_share_net \

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

The share also can be created from a share snapshot. For details, see
shared_file_systems_snapshots.

See the share in a share list:

$ manila list
+--------------------------------------+---------+------+-------------+-----------+-----------+-----------------+----------------------+-------------------+
| ID                                   | Name    | Size | Share Proto | Status    | Is Public | Share Type Name | Host                 | Availability Zone |
+--------------------------------------+---------+------+-------------+-----------+-----------+-----------------+----------------------+-------------------+

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

Check the share status and see the share export locations. After
creating status share should have status
available:

$ manila show Share2
+----------------------+----------------------------------------------------------------------+

projects for the share if you need:

$ manila update Share2 --description "My second share. Updated" --is-public False

$ manila show Share2

Share metadata

If you want to set the metadata key-value pairs on the share,
run:

$ manila metadata Share2 set project=my_abc deadline=01/20/16

Get all metadata key-value pairs of the share:

$ manila metadata-show Share2
+----------+----------+
| Property | Value    |
+----------+----------+
| aim      | testing  |
| project  | my_abc   |
| deadline | 01/20/16 |
+----------+----------+

You can update the metadata:

$ manila metadata-update-all Share2 deadline=01/30/16
+----------+----------+
| Property | Value    |
+----------+----------+
| deadline | 01/30/16 |
+----------+----------+

You also can unset the metadata using manila metadata
<share_name> unset <metadata_key(s)>
.

Reset share state

As administrator, you can reset the state of a share.

Use manila reset-state [–state <state>]
<share>
command to reset share state, where
state indicates which state to assign the share. Options
include available, error,
creating, deleting,
error_deleting states.

$ manila reset-state Share2 --state deleting

Delete and force-delete
share

You also can force-delete a share. The shares cannot be deleted in
transitional states. The transitional states are creating,
deleting, managing, unmanaging,
migrating, extending, and
shrinking statuses for the shares. Force-deletion deletes
an object in any state. Use the policy.yaml file to grant
permissions for this action to other roles.

Tip

The configuration file policy.yaml may be used from
different places. The path /etc/manila/policy.yaml is one
of expected paths by default.

Use manila delete <share_name_or_ID> command
to delete a specified share:

$ manila delete %share_name_or_id%
$ manila delete %share_name_or_id% --consistency-group %consistency-group-id%

If you try to delete the share in one of the transitional state using
soft-deletion you’ll get an error:

$ manila delete Share2
Delete for share 195e3ba2-9342-446a-bc93-a584551de0ac failed: Invalid share: Share status must be one of ('available', 'error', 'inactive'). (HTTP 403) (Request-ID: req-9a77b9a0-17d2-4d97-8a7a-b7e23c27f1fe)
ERROR: Unable to delete any of the specified shares.

A share cannot be deleted in a transitional status, that it why an
error from python-manilaclient appeared.

Print the list of all shares for all projects:

$ manila list --all-tenants
+--------------------------------------+---------+------+-------------+-----------+-----------+-----------------+----------------------+-------------------+
| ID                                   | Name    | Size | Share Proto | Status    | Is Public | Share Type Name | Host                 | Availability Zone |

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

Force-delete Share2 and check that it is absent in the list of
shares, run:

$ manila force-delete Share2

$ manila list
+--------------------------------------+---------+------+-------------+-----------+-----------+-----------------+----------------------+-------------------+

Manage access to share

The Shared File Systems service allows to grant or deny access to a
specified share, and list the permissions for a specified share.

To grant or deny access to a share, specify one of these supported
share access levels:

  • rw. Read and write (RW) access. This is the default
    value.
  • ro. Read-only (RO) access.

You must also specify one of these supported authentication
methods:

  • ip. Authenticates an instance through its IP
    address. A valid format is XX.XX.XX.XX or
    XX.XX.XX.XX/XX. For example 0.0.0.0/0.
  • user. Authenticates by a specified user or group
    name. A valid value is an alphanumeric string that can contain some
    special characters and is from 4 to 32 characters long.
  • cert. Authenticates an instance through a TLS
    certificate. Specify the TLS identity as the IDENTKEY. A valid value is
    any string up to 64 characters long in the common name (CN) of the
    certificate. The meaning of a string depends on its interpretation.
  • cephx. Ceph authentication system. Specify the Ceph
    auth ID that needs to be authenticated and authorized for share access
    by the Ceph back end. A valid value must be non-empty, consist of ASCII
    printable characters, and not contain periods.

Try to mount NFS share with export path
10.0.0.4:/shares/manila_share_a5fb1ab7_0bbd_465b_ac14_05706294b6e9
on the node with IP address 10.0.0.13:

$ sudo mount -v -t nfs 10.0.0.4:/shares/manila_share_a5fb1ab7_0bbd_465b_ac14_05706294b6e9 /mnt/
mount.nfs: timeout set for Tue Oct  6 10:37:23 2015
mount.nfs: trying text-based options 'vers=4,addr=10.0.0.4,clientaddr=10.0.0.13'
mount.nfs: mount(2): Permission denied
mount.nfs: access denied by server while mounting 10.0.0.4:/shares/manila_share_a5fb1ab7_0bbd_465b_ac14_05706294b6e9

An error message “Permission denied” appeared, so you are not allowed
to mount a share without an access rule. Allow access to the share with
ip access type and 10.0.0.13 IP address:

$ manila access-allow Share1 ip 10.0.0.13 --access-level rw
+--------------+--------------------------------------+
| Property     | Value                                |
+--------------+--------------------------------------+
| share_id     | 10f5a2a1-36f5-45aa-a8e6-00e94e592e88 |
| access_type  | ip                                   |
| access_to    | 10.0.0.13                            |
| access_level | rw                                   |
| state        | new                                  |
| id           | de715226-da00-4cfc-b1ab-c11f3393745e |
+--------------+--------------------------------------+

Try to mount a share again. This time it is mounted successfully:

$ sudo mount -v -t nfs 10.0.0.4:/shares/manila_share_a5fb1ab7_0bbd_465b_ac14_05706294b6e9 /mnt/

Since it is allowed node on 10.0.0.13 read and write access, try to
create a file on a mounted share:

$ cd /mnt
$ ls
lost+found
$ touch my_file.txt

Connect via SSH to the 10.0.0.4 node and check new file
my_file.txt in the
/shares/manila_share_a5fb1ab7_0bbd_465b_ac14_05706294b6e9
directory:

$ ssh 10.0.0.4
$ cd /shares
$ ls
manila_share_a5fb1ab7_0bbd_465b_ac14_05706294b6e9
$ cd manila_share_a5fb1ab7_0bbd_465b_ac14_05706294b6e9
$ ls
lost+found  my_file.txt

You have successfully created a file from instance that was given
access by its IP address.

Allow access to the share with user access type:

$ manila access-allow Share1 user demo --access-level rw
+--------------+--------------------------------------+
| Property     | Value                                |
+--------------+--------------------------------------+
| share_id     | 10f5a2a1-36f5-45aa-a8e6-00e94e592e88 |
| access_type  | user                                 |
| access_to    | demo                                 |
| access_level | rw                                   |
| state        | new                                  |
| id           | 4f391c6b-fb4f-47f5-8b4b-88c5ec9d568a |
+--------------+--------------------------------------+

Note

Different share features are supported by different share drivers.
For the example, the Generic driver with the Block Storage service as a
back-end doesn’t support user and cert
authentications methods. For details of supporting of features by
different drivers, see Manila share features support mapping
<https://docs.openstack.org/manila/latest/admin
/share_back_ends_feature_support_mapping.html>
.

To verify that the access rules (ACL) were configured correctly for a
share, you list permissions for a share:

$ manila access-list Share1
+--------------------------------------+-------------+------------+--------------+--------+
| id                                   | access type | access to  | access level | state  |
+--------------------------------------+-------------+------------+--------------+--------+
| 4f391c6b-fb4f-47f5-8b4b-88c5ec9d568a | user        | demo       | rw           | error  |
| de715226-da00-4cfc-b1ab-c11f3393745e | ip          | 10.0.0.13  | rw           | active |
+--------------------------------------+-------------+------------+--------------+--------+

Deny access to the share and check that deleted access rule is absent
in the access rule list:

$ manila access-deny Share1 de715226-da00-4cfc-b1ab-c11f3393745e

$ manila access-list Share1
+--------------------------------------+-------------+-----------+--------------+-------+
| id                                   | access type | access to | access level | state |
+--------------------------------------+-------------+-----------+--------------+-------+
| 4f391c6b-fb4f-47f5-8b4b-88c5ec9d568a | user        | demo      | rw           | error |
+--------------------------------------+-------------+-----------+--------------+-------+
