For those of you who might still be waiting for OpenOffice to start
up, the noteworthy section of pvfs2-ping output looks like this:

(5) Verifying that all servers are responding...
   meta servers:
   tcp://jw3:3334 Ok
   data servers:
Error: bmi_tcp: Transport endpoint is not connected
Warning: non PVFS2 error code (6b):
*** msgpair did not complete successfully: Transport endpoint is not connected
   tcp://jw1:3334 Ok

in the future, plain text would be the best way to send information

In general, when pvfs2-ping fails to work, you have to go back and
double-check the basics.  
- On all 5 machines, is pvfs2-server still running?  
- From the client, can you ping all 5 machines?
- Do you have any hardware or software firewalls that prevent access
  to the pvfs2 port (3334)?  Try telnetting to port 334

Please respond with the answers to these three questions and we'll go
from there.
