I had a RHEL 6.7, cman + rgmanager cluster that I've built many times
before. Oddly, I just hit this error:
====
[root at node2 ~]# /etc/init.d/clvmd start
Starting clvmd: clvmd could not connect to cluster manager
Consult syslog for more information

syslog:

Sep 24 23:00:30 node2 kernel: dlm: Using SCTP for communications
Sep 24 23:00:30 node2 clvmd: Unable to create DLM lockspace for CLVM:
Address already in use
Sep 24 23:00:30 node2 kernel: dlm: Can't bind to port 21064 addr number 1
Sep 24 23:00:30 node2 kernel: dlm: cannot start dlm lowcomms -98
====
There are no iptables rules:
====
[root at node2 ~]# iptables-save
====
And there are no DLM lockspaces, either:
====
[root at node2 ~]# dlm_tool ls
[root at node2 ~]#
====
I tried withdrawing the node from the cluster entirely, the started cman
alone and tried to start clvmd, same issue.
Pinging between the two nodes seems OK:

I have RRP configured and pings work on the second network, too:

Nothing special there at all.
While writing this email though, I saw this on the other node:

Certainly *looks* like a network problem, but I can't see what's
wrong... Any ideas?
Thanks!
