Thanks for including your steps.  You've got the right idea, but there
are a few things you are missing before 'pvfs2-ping' will work:

You've got your config files now (/etc/pvfs2-fs.conf and
seven files like /etc/pvfs2-server.conf-comp-pvfs-0-XX ), so that's a
good start.   When i say 'comp-pvfs-0-XX' i mean "the name of an I/O
or metadata server"

You'll have to somehow get those files from prospero to the other
nodes.
http://www.pvfs.org/pvfs2/pvfs2-quickstart.html#sec:server-config
describes one approach using 'scp', but it's probably easiest to just
"scp /etc/pvfs2-* comp-pvfs-0-XX:/etc/" for each of your servers.

Then on each node, you need to create the storage space with the '-f'
option to pvfs2-server:

    pvfs2-server -f pvfs2-fs.conf pvfs2-server.conf-comp-pvfs-0-XX

After you create the storage space, then you can start the servers.
Again, do this on each node (note, there's no -f option):

   pvfs2-server pvfs2-fs.conf pvfs2-server.conf-comp-pvfs-0-XX

Once all the servers are running (one on each of your machines) you'll
be able to run pvfs2-ping.  Once pvfs2-ping reports everything is OK,
then you can move on to the kerrnel interface.
