For pvfs2-ping to work it needs access to a pvfs2tab file. You can see in the error message the various places the utility looks for that file. I would recommend placing the pvfs2tab file in the same location as you did on your client node. One other possibility is to place a pvfs2tab file in the current directory your shell is in when running the pvfs2-ping command.
It looks like, what you are calling "Client node", is also running a pvfs2-server process. That is okay, I just wanted to make sure that is what you intended. It appears that the pvfs2-server process is not running for some reason on the host mds10. On mds10 look at the file /tmp/pvfs2-server.log. It should provide a reason why the server failed to start on that host. If you changed the default LogFile parameter in the configuration file you should look at the file in that location.
