================================================================================
A Gluster license request for $count machines has been written to -

  ./license.req

You may now submit this license request file at -

  http://supportservices.gluster.com/

Or mail it as an email attachment to support@gluster.com.

Once you have obtained the signed license file (license.asc) you need
to copy it back into this machine and run the following command -

  sh# gluster-lic-install ./license.asc


NOTE: Every time you 'peer probe' a new server into the cluster, you
need to repeat this process within 30 days of probing.
