Description of problem: In some network environments the first ping may fail. validation-scripts/all-nodes.sh Only pings once. That sometimes caused the deployment to fail on the node validation steps. After changing it to ping -c 10 it works reliably.
This bug did not make the OSP 8.0 release. It is being deferred to OSP 10.
Obsolete, please re-open if still valid with more specific info about the environments.
