Hello Robert,

I am just checking. I have the following configured for the mean time 
until I get the other machine.

root at 0-0-0:~] cat /etc/drbd.d/drbd.res
resource r0 {
     device        minor 0;
     disk        /dev/system/drbd;
     meta-disk     internal;

     on 0-0-0.kingsley.co.za {
     on 0-0-1.kingsley.co.za {
     startup {
         wfc-timeout        1;
         degr-wfc-timeout    1;
         become-primary-on    0-0-0.kingsley.co.za;

[root at 0-0-0:~] cat /proc/drbd
version: 8.3.7 (api:88/proto:86-91)
srcversion: EE47D8BF18AC166BE219757

Thank you
