At Austin 2016 summit there were several improvements to Share migration feature discussed. This patch implements these changes. Changes are: - Added 'Writable' API parameter: user chooses whether share must remain writable during migration. - Added 'Preserve Metadata' API parameter: user chooses whether share must preserve all file metadata on migration. - Added 'Non-disruptive' API parameter: user chooses whether migration of share must be performed non-disruptively. - Removed existing 'Notify', thus removing 1-phase migration possibility. - Renamed existing 'Force Host Copy' parameter to 'Force Host-assisted Migration'. - Renamed all 'migration_info' and 'migration_get_info' entries to 'connection_info' and 'connection_get_info'. - Updated driver interfaces with the new API parameters, drivers must respect them. - Changed share/api => scheduler RPCAPI back to asynchronous. - Added optional SHA-256 validation to perform additional check if bytes were corrupted during copying. - Added mount options configuration to Data Service so CIFS shares can be mounted. - Driver may override _get_access_mapping if supports a different access_type/protocol combination than what is defined by default. - Added CIFS share protocol support and 'user' access type support to Data Service. - Reset Task State API now allows task_state to be unset using 'None' value. - Added possibility to change share-network when migrating a share. - Bumped microversion to 2.22. - Removed support of all previous versions of Share Migration APIs.

more combinations of share protocols and access types support
|
|
to the Data Service.
|
|

|
|
procedure to maintain the share writable, preserve its metadata
|

|
|
respective 'user' access type support, through
|

deprecations:

|
|
to 'force_host_assisted_migration', to better represent

|
|
upgrades:
|
|
