Create and manage shares¶
General Concepts¶
A share is filesystem storage that you can create with manila. You can pick
a network protocol for the underlying storage, manage access and perform
lifecycle operations on the share via the manila command line tool.
Before we review the operations possible, lets take a look at certain important terms:
share network: This is a network that your shares can be exported to. Exporting shares to your own self-service isolated networks allows manila to providehard network pathdata isolation guarantees in a multi-tenant cloud. To do so, under the hood, manila creates isolatedshare servers, and plugs them into your network. These share servers manage exports of your shares, and can connect to authentication domains that you determine. Manila performs all the lifecycle operations necessary on share servers, and you needn’t worry about them. The important thing to note is that your cloud administrator must have made a share type with extra-specdriver_handles_share_servers=Truefor you to be able to use share networks and create shares on them. See Create and manage share networks and Create and manage share network subnets for more details.share type: A share type is a template made available by your administrator. You must always specify a share type when creating a share, unless you would like to use the default share type. It’s possible that your cloud administrator has not made a default share type accessible to you. Share types specify some capabilities for your use:
Capability |
Possible values |
Consequence |
|---|---|---|
driver_handles_share_servers |
true or false |
you can or cannot use share networks to create shares |
snapshot_support |
true or false |
you can or cannot create snapshots of shares |
create_share_from_snapshot_support |
true or false |
you can or cannot create clones of share snapshots |
revert_to_snapshot_support |
true or false |
you can or cannot revert your shares in-place to the most recent snapshot |
mount_snapshot_support |
true or false |
you can or cannot export your snapshots and mount them |
replication_type |
dr |
you can create replicas for disaster recovery, only one active export allowed at a time |
readable |
you can create read-only replicas, only one writable active export allowed at a time |
|
writable |
you can create read/write replicas, any number of active exports per share |
|
availability_zones |
a list of one or more availability zones |
shares are limited to these availability zones |
Note
When
replication_typeextra specification is not present in the share type, you cannot create share replicasWhen the
availability_zonesextra specification is not present in the share type, the share type can be used in all availability zones of the cloud.
statusof resources: Resources that you create or modify with manila may not be “available” immediately. The API service is designed to respond immediately and the resource being created or modified is worked upon by the rest of the service stack. To indicate the readiness of resources, there are several attributes on the resources themselves and the user can watch these fields to know the state of the resource. For example, thestatusattribute in shares can convey some busy states such as “creating”, “extending”, “shrinking”, “migrating”. These “-ing” states end in a “available” state if everything goes well. They may end up in an “error” state in case there is an issue. See Troubleshooting asynchronous failures to determine if you can rectify these errors by yourself. If you cannot, consulting a more privileged user, usually a cloud administrator, might be useful.snapshot: This is a point-in-time copy of a share. In manila, snapshots are meant to be crash consistent, however, you may need to quiesce any applications using the share to ensure that the snapshots are application consistent. Cloud administrators can enable or disable snapshots via share type extra specifications.security service: This is an authentication domain that you define and associate with your share networks. It could be an Active Directory server, a Lightweight Directory Access Protocol server, or Kerberos. When used, access to shares can be controlled via these authentication domains. You may even combine multiple authentication domains.

Note
This Manila API does not validate the subnet information you supply right away. The validation is performed when creating a share with the share network. This is why, you do not see some subnet information populated on the share network resource until at least one share is created with it.
