I'm not an expert but "WFConnection" means "Waiting For Connection". I
think that "StandAlong" means that it gave up on the other side but
not sure (and I lost the link to the web page which explained
/proc/drbd).
Two things I'd look at:
1. Firewall - make sure the hosts can talk to each other on TCP port
9999 (verify with tcpdump, maybe).
2. The IP address of axsrnd2 is 10.0.4.144 (i.e. the IP address you
include for each host is that of the host itself, not the other one),
right?
