I think I understand what you are saying up to here. In this case, can you do 'xrdfs ... stat /'. This
may give you an error like the following. But it is still a legitimate response telling you the server
is running:
$ xrdfs root://myXcache stat /
[ERROR] Server responded with an error: [3010] Stating path '/' is disallowed.
Or you can do
$ xrdfs root://myXcache query config version
v5.0.2
