Description
Our test setup contains 16 MDTs. Our clients only ever see 10 MDTs. All output below is from a client with the file system mounted. All were formatted at the same time with the same script and same mgs nid.
Attempts to use any MDT that is not listed fails (i.e. lfs mkdir --index=10 will fail).
