Views on the Same Path
If there are multiple views on the same path, including views on nested paths, all of their view policies must have the same security flavor.
Nested Views
It is possible to create different views on paths that are nested under each other. For example, you can have a view on the path /a/b and another view on the path /a/b/c. Each view can use a different view policy.
This is useful, for example, if you want to give a larger set of NFS client hosts read/write access to the higher level directory while giving a subset of NFS client hosts read/write access to a deeper directory.
However:
It is not recommended to set any multiprotocol behavior settings (such as path length limit or allowed characters which are options you can set in the view policy), on a child directory's view that are different to the security settings of its parent directory's view, since this could result in unpredictable behavior with permission authorization.
S3 bucket views cannot have other views nested under them or on the same path.
If a view has NFSv4 enabled as a protocol, then all views located above that view must also have NFSv4 enabled.
Multiprotocol File Access
When you enable the SMB protocol on a view together with NFSv3, NFSv4.1 or S3, non-simultaneous access to any files in the view from all enabled protocols is fully supported by default.
