[Pvfs2-users] connection refused during PVFS client configuration

[Kevin Harms]

   The problem is the fact that the initial storage space was not  
created so your server isn't running. You should be able to see this  
in the log.

   Ubuntu 8.10 has bdb 4.7 by default but it has packages for the 4.6  
version as well. (Something like apt-get install libdb-4.6-dev)  
Rebuild you server with bdb 4.6 and those errors while creating the  
storage space should go away. Alternatively you could get the latest  
version of PVFS out of CVS which supports bdb 4.7. Just as an FYI, the  
kernel module will not build with 2.7.1 and Ubuntu 8.10 either.
