- fsync() force deletes file from local cache and invalidates attribute cache. This forces Cloudfuse to refresh the file metadata and contents on next open call to that file.
- fsyncdir() invalidates metadata of that directory recursively. This forces Cloudfuse to refresh metadata of any child of that directory on next metadata query by kernel.
- Cloudfuse does not support overlapping mount paths. While running multiple instances of Cloudfuse make sure each instance has a unique and non-overlapping mount point.
- Cloudfuse does not support co-existence with NFS on same mount path. Behavior in this case is undefined.
- For non-HNS Azure accounts (flat name space), Cloudfuse expects special directory marker files to identify any directory. If such files do not exist on storage and '--virtual-directory=true' cli flag is not provided, Cloudfuse will fail to identify directories.
- On non-HNS Azure accounts chmod operations are not permitted and Cloudfuse will return back success in such cases.
