Manage and unmanage share snapshot

To manage a share snapshot means that an administrator, rather than a share driver, manages the storage lifecycle. This approach is appropriate when an administrator manages share snapshots outside of the Shared File Systems service and wants to register it with the service.

To unmanage a share snapshot means to unregister a specified share snapshot from the Shared File Systems service. Administrators can revert an unmanaged share snapshot to managed status if needed.

Unmanage a share snapshot

The unmanage operation is not supported for shares that were created on top of share servers and created with share networks. The Share service should have the option driver_handles_share_servers = False set in the manila.conf file.

To unmanage managed share snapshot, run the openstack share snapshot abandon <share_snapshot> command. Then try to print the information about the share snapshot. The returned result should indicate that Shared File Systems service won’t find the share snapshot:

$ openstack share snapshot abandon my_test_share_snapshot
$ openstack share snapshot show my_test_share_snapshot
ERROR: No sharesnapshot with a name or ID of 'my_test_share_snapshot'
exists.

Manage a share snapshot

To register the non-managed share snapshot in the File System service, run the openstack share snapshot adopt command:

openstack share snapshot adopt [--name <name>] [--description <description>]
                               [--driver-option <key=value>]
                               <share> <provider_location>

The positional arguments are:

• share. Name or ID of the share.

• provider_location. Provider location of the share snapshot on the backend.

The driver_options is an optional set of one or more key and value pairs that describe driver options.

To manage share snapshot, run:

$ openstack share snapshot adopt \

    --name my_test_share_snapshot \
    --description "My test share snapshot" \
