features:
- |
Add new CinderNfsSnapshotSupport parameter, which controls whether
cinder's NFS driver supports snapshots. The default value is True.
upgrade:
- |
Cinder's NFS driver does not support snapshots unless the feature is
explicitly enabled (this policy was chosen to ensure compatibility with
very old versions of libvirt). The CinderNfsSnapshotSupport default value
is True, and so the new default behavior enables NFS snapshots. This
change is safe because it just enables a capability (i.e. snapshots)
that other cinder drivers generally provide.
