Share Migration
|
|
===============
|
|
As an administrator, you can migrate a share with its data from one
|
|
location to another in a manner that is transparent to users and workloads.
|
|
|
|
Possible use cases for data migration include:
|
|
|
|
- Bring down a physical storage device for maintenance without disrupting
|
|
workloads.
|
|
- Modify the properties of a share.
|
|
- Free up space in a thinly-provisioned back end.
|
|
|
|
.. note::
|
|
|
|
Share Migration APIs are part an the ``experimental`` feature
|
|
introduced in version 2.5. The APIs may change or be removed in further
|
|
versions of the Shared File Systems API. The changes are
|
|
documented within each API below. All experimental APIs require the
|
|
``X-OpenStack-Manila-API-Experimental: True`` header to be
|
|
sent in the requests.
|
|
|
|
|
|
Migrate share (versions 2.5 to 2.14)
|
|
=========================================
|
|
|
|
.. rest_method:: POST /v2/{tenant_id}/shares/{share_id}/action
|
|
|
|
Migrates a share from one back end to another.
|
|
|
|
You can migrate a share from one back end to another but both back
|
|
ends must set the ``driver_handles_share_servers`` parameter to
|
|
``False``. If a share driver handles one of the back ends, this
|
|
action is not supported. You can configure a back end in the
|
|
``manila.conf`` file.
