How to set up NFS?

Question

NFS

The host already has a NFS-shared directory /test_h, on the client it is mounted as /test_c
I'm trying to mount another directory there from the same host /test_h2. I mount it as /test_c2

And here on the client in this /test_c2 the contents from /test_h (test_c) are displayed

Why can this be so?

Answer 1

In NFSv4 you can't export more than 1 root folder (exported via fsid=0) - thus - no matter what you mount, it will be the root of all fs.
Just specify a different id for exports and everything will work.
