This patch adds support for share server migration between NetApp ONTAP drivers. This operation is now supported for migrating a share server and all its resources between two different clusters. Share server migration relies on ONTAP features available only in versions equal and greater than ``9.4``. Also, in order to have share server migration working across ONTAP clusters, they must be peered in advance. At this moment, share server migration doesn't support migrate a share server without disrupting the access to shares, since the export locations are updated at the migration complete phase. The driver doesn't support changing security services while changing the destination share network. This functionality can be added in the future.

The NetApp ONTAP driver now supports migration of share servers across
|
||
clusters. While migrating a share server, the source remains writable
|
||
during the first phase of the migration, until the cutover is issued. It is
|
||
possible to specify a new share network for the destination share server,
|
||
only if the associated security services remain unchanged.
|
||
Share server migration relies on ONTAP features available only in versions
|
||
equal and greater than ``9.4``. In order to have share server migration
|
||
working across ONTAP clusters, they must be peered in advance.
|
||
In order to adapt to different workloads and provide more flexibility on
|
||
managing cluster’s free space a new configuration option was added:
|
||
|
||
- ``netapp_server_migration_check_capacity``:
|
||
Specifies if a capacity validation at the destination backend must be
|
||
made before proceeding with the share server migration. When enabled,
|
||
the NetApp driver will validate if the destination pools can hold all
|
||
shares and snapshots belonging to the source share server.
