Use the Shared Filesystems service¶
Available since MOSK 22.5 TechPreview
This section provides instructions on how to create a share filesystem resource using default service settings.
Prepare an environment to work with Manila¶
Create a share network:
openstack share network create --name <share-network-name> \ --neutron-net-id <neutron-net-id> \ --neutron-subnet-id <neutron-subnet-id>
For example, use the command below to create the
demo_share_netshare network with the followingneutron-net-idandneutron-subnet-id:2a23fceb-eeed-439c-8506-ef489362d1eeis the ID of thedemo_netnetwork which the virtual machine is connected to479b27e4-0b73-4f8d-a838-d330d72578eais the ID of thedemo_subnetsubnet of thedemo_netnetwork, which is connected to a public router
openstack share network create --name demo_share_net \ --neutron-net-id 2a23fceb-eeed-439c-8506-ef489362d1ee \ --neutron-subnet-id 479b27e4-0b73-4f8d-a838-d330d72578ea
Example of a positive system response:

Verify that the share network has been successfully created:
openstack share network list
Example of a positive system response:
+--------------------------------------+----------------+ | ID | Name | +--------------------------------------+----------------+ | 52438b02-7a06-4dfc-a0a9-cbc773bd4389 | demo_share_net | +--------------------------------------+----------------+
Create a share file system and grant access to it¶
Create a 1Gb NFS share:
openstack share create --name <share-name> NFS 1 \ --share-network <share-network-name>
For example, to create the
demo_shareshare:openstack share create --name demo_share NFS 1 --share-network demo_share_net
Example of a positive system response:
+---------------------------------------+--------------------------------------+ | Field | Value | +---------------------------------------+--------------------------------------+ | access_rules_status | active | | availability_zone | None | | create_share_from_snapshot_support | False | | created_at | 2022-11-23T15:34:28.604430 | | description | None | | has_replicas | False | | host | | | id | 9e864fc8-c3f6-464e-a91f-3aad236b1c8d | | is_public | False | | is_soft_deleted | False | | metadata | {} | | mount_snapshot_support | False | | name | demo_share | | progress | None | | project_id | 6a1e7dfe64164fb884e146634a84b204 | | replication_type | None | | revert_to_snapshot_support | False | | scheduled_to_be_deleted_at | None | | share_group_id | None | | share_network_id | 52438b02-7a06-4dfc-a0a9-cbc773bd4389 | | share_proto | NFS | | share_server_id | None | | share_type | dbbca99c-268e-490a-b4de-b420d407e4d7 | | share_type_name | default | | size | 1 | | snapshot_id | None | | snapshot_support | False | | source_share_group_snapshot_member_id | None | | status | creating | | task_state | None | | user_id | c2a226097e1f442dbbd065534e61c20a | | volume_type | default | +---------------------------------------+--------------------------------------+
Verify that the share creation has been finalized:
openstack share list
Example of a positive system response:
+--------------------------------------+------------+------+-------------+-----------+-----------+-----------------+-----------------------------------------------------------------------+-------------------+ | ID | Name | Size | Share Proto | Status | Is Public | Share Type Name | Host | Availability Zone | +--------------------------------------+------------+------+-------------+-----------+-----------+-----------------+-----------------------------------------------------------------------+-------------------+ | 9e864fc8-c3f6-464e-a91f-3aad236b1c8d | demo_share | 1 | NFS | available | False | default | ok-rs-vwiza7ejeugp-1-swk6jtqte3gp-server-ovr6zpdtas6y@generic#GENERIC | nova | +--------------------------------------+------------+------+-------------+-----------+-----------+-----------------+-----------------------------------------------------------------------+-------------------+
Grant the
rwaccess to the virtual machine:openstack share access create <share-name> ip <VM-IP> --access-level rw
For example:
openstack share access create demo_share ip 192.0.2.59 --access-level rw
Example of a positive system response:
+--------------+--------------------------------------+ | Field | Value | +--------------+--------------------------------------+ | id | b356fdd2-b019-4fef-95da-93bc7a6e407d | | share_id | 9e864fc8-c3f6-464e-a91f-3aad236b1c8d | | access_level | rw | | access_to | 192.0.2.59 | | access_type | ip | | state | queued_to_apply | | access_key | None | | created_at | 2022-11-23T15:40:42.540847 | | updated_at | None | | properties | | +--------------+--------------------------------------+
List grants for the share you created:
openstack share access list <share-name>
For example, to list the grants for the
demo_shareshare:openstack share access list demo_share +--------------------------------------+-------------+-------------+--------------+--------+------------+----------------------------+------------+ | ID | Access Type | Access To | Access Level | State | Access Key | Created At | Updated At | +--------------------------------------+-------------+-------------+--------------+--------+------------+----------------------------+------------+ | b356fdd2-b019-4fef-95da-93bc7a6e407d | ip | 192.0.2.59 | rw | active | None | 2022-11-23T15:40:42.540847 | None | +--------------------------------------+-------------+-------------+--------------+--------+------------+----------------------------+------------+
Connect the share to the virtual machine¶
Obtain the share URL:
openstack share show <share-name> -c export_locations -f value
For example, to obtain the
demo_shareURL:openstack share show demo_share -c export_locations -f value
Example of a positive system response where the URL is
10.254.0.68:/shares/share-04c212a4-a547-4f06-b8eb-3b5006878c6e:id = 29b59502-6165-4ec5-b174-76553490510c path = 10.254.0.68:/shares/share-04c212a4-a547-4f06-b8eb-3b5006878c6e preferred = False share_instance_id = 04c212a4-a547-4f06-b8eb-3b5006878c6e is_admin_only = False id = a6fb11a1-d015-4de3-8b30-98e0d2027c02 path = 10.254.0.68:/shares/share-04c212a4-a547-4f06-b8eb-3b5006878c6e preferred = False share_instance_id = 04c212a4-a547-4f06-b8eb-3b5006878c6e is_admin_only = True
Log in to the virtual machine using the share URL obtained in the previous step and run as root:
mount -t nfs <share-URL> /mnt/
Verify that the share is mounted and has a property size:
df -h /mnt
Example of a positive system response:
Filesystem Size Used Avail Use% Mounted on 10.254.0.68:/shares/share-04c212a4-a547-4f06-b8eb-3b5006878c6e 974M 0 907M 0% /mnt
