Looks like you are trying to mount "/" via v3. "/" is reserved for
psuedo file system which can be mounted only via "v4" AFAIK.
Please try using a different path other than '/' in your Export Block.

In this case, the path exported is
"/storage" for v3 and
"/cephfs" for v4

As I said, '/' is reserved, you may need to use different Path here.
