- Add Database migration to introduce the column on the share instances model. - Set the field to True if creating read-only secondary replicas, unset while promoting them. - Set the field to True if drivers don't support writable access to migrating shares, or if using host assisted migration. Unset if migration fails, or is canceled. - Expose the field via share-instances and share-replicas APIs to administrators. Supporting read only-access rules is part of the minimum driver requirements in manila.

The share migration feature was improved to support
|
|
migrating snapshots where possible and provide a more
|
|
deterministic user experience.
|
|
features:
|
|
- Added 'preserve_snapshots' parameter to share migration API.
|
|
upgrade:
|
|
- All share migration driver-assisted API parameters are
|
|
now mandatory.
|
|
- Improvements to the share migration API have been qualified
|
|
with the driver assisted migration support that exists in the
|
|
ZFSOnLinux driver. However, this driver does not currently
|
|
support preserving snapshots on migration.
|
|
- Snapshot restriction in share migration API has been
|
|
changed to return error only when parameter
|
|
force-host-assisted-migration is True.
|
|
deprecations:
|
|
- Support for the experimental share migration APIs has been
|
|
dropped for API microversions prior to 2.30.
|
|
fixes:
|
|
- Added check to validate that host assisted migration cannot
|
|
be forced while specifying driver assisted migration options.
|
|
- The share migration API can only be invoked when at least one
|
|
parameter within (host, share-network, share-type) is expected
|
|
to be changed.
