# Comments from https://wiki.duraspace.org/display/FEDORA4x/Deploying+a+Fedora+Cluster :
# - The initial_hosts attribute should only include remote hosts for the local
#   node, not itself.
# - The num_initial_members should match the count of remote hosts, i.e. it
#   does not include the local node either.
# - If you are running just one port on each host, then port_range will be 0.
# - IP resolution is important if you use DNS names. The locally resolved IP
#   of each remote host must match the TCP@bind_addr in the remote host config.
