This means the node you are working on is not seeing the second computer at all: > drbd1: Primary/Unknown --> Secondary/Unknown > drbd1: Secondary/Unknown --> Primary/Unknown - Make sure drbd module is loaded on the second node lsmod | grep drbd - Make sure drbd is started on that node es well /etc/init.d/drbd start or whatever your startup script is. If the above are truth and you still get /Unknown, then check your network connections: - Check your cables - Make sure your network cards are configured to start on boot If using any redhat like system then look in /etc/sysconfig/network-scripts/ifcg-ethX to make sure that it has: ONBOOT=yes IPADDR=X.X.X.X NETMASK=X.X.X.X - Make sure you can ping the IP of the other node's network card used for drbd. - Use nmap to see if the port is opened (Maybe you forgot to add a permanent firewall rule to open the appropriate ports for your drbd connection). nmap -p [DRBD PORT NUMBER HERE] other_drbd_host_ip_address If none of the above works then I am out of hints... Hope this helps, Diego
