**********************************************************************
    Welcome to the PVFS2 Configuration Generator:

This interactive script will generate configuration files suitable
for use with a new PVFS2 file system.  Please see the PVFS2 quickstart
guide for details.

**********************************************************************
You must first select the network protocol that your file system will use.
The only currently supported options are "tcp", "gm", "mx", "ib", and "portals".
(For multi-homed configurations, use e.g. "ib,tcp".)

* Enter protocol type [Default is tcp]:

Choose a TCP/IP port for the servers to listen on.  Note that this
script assumes that all servers will use the same port number.

* Enter port number [Default is 3334]:

Choose a directory for each server to store data in.

* Enter directory name: [Default is /pvfs2-storage-space]:

Choose a file for each server to write log messages to.

* Enter log file location [Default is /tmp/pvfs2-server.log]:

Next you must list the hostnames of the machines that will act as
I/O servers.  Acceptable syntax is "node1, node2, ..." or "node{#-#,#,#}".

* Enter hostnames [Default is localhost]:

Use same servers for metadata? (recommended)

* Enter yes or no [Default is yes]:

Configured a total of 1 servers:
1 of them are I/O servers.
1 of them are Metadata servers.

* Would you like to verify server list (y/n) [Default is n]?
