walkthrough after initial automated setup of gxfsadm server

After the server has been successfully setup using the gxfsberry it needs to be attached to the RHEL license server. For that purpose the servers needs to have internet access. This can either be done by configuring a network connection. The gxfsberry is configured to do NAT on the WLAN interface. Or the normal way can be used. http_proxy and/or https_proxy needs to be set by environmental variable.<br>

as next step pcs needs to be triggered to restart drbd. issue a pcs resource cleanup. After the drbd devices are visible, but are in state connecting. Use the guideline under https://www.recitalsoftware.com/blogs/29-howto-resolve-drbd-split-brain-recovery-manually to revalidate the connection.
