Hi, I am facing a DNS resolution problem with 2 of my hosts in my cluster. /etc/hosts file is configured like : ip FQDN hostname for all hosts python -c "import socket; print socket.getfqdn(); print socket.gethostbyname(socket.getfqdn())" gives me back the correct values , also i can ping each host with hostname normally But still i cannot avoid this issue about DNS resolution . Also the hosts IDs are different . Any ideas pls ? ... View more
