You have been granted a limited, five day operational license for Gluster.

To get a free full featured 30-day license with detailed documentation and access
to engineering support, please copy and paste the following URL in your browser:

This system is unlicensed. To obtain a license you have to first generate
a license request and get it signed. Note that a license request is for the
entire cluster of systems and therefore you need to first start all your
systems (ensure ssh connectivity among them) and peer probe them all as well.

To generate a license request, run this command and follow the instructions:

  sh# gluster-lic-request
