Hi,
I have installed DRBD+OCFS2 and working Amazon EC2, however as a previous
thread suggested we should use Pacemaker in order to get OCFS modified in
runtime (modify/del nodes).
Pacemaker/corosync and other components were very straight forward installing
via Lucid-Cluster and Ubuntu-HA, but at the first steps I experienced some
problems with CoroSync regarding network connectivity.
Unfortunately, Amazon does not allow Multicast, so I used udpu once it would
be the only way to get it working, but when I started I got same error on logs
Even with all traffic allowed, no apparmor (ubuntu), no iptables locally at all:
Jun 29 15:11:11 corosync [TOTEM ] Totem is unable to form a cluster because of
an operating system or network fault. The most common cause of this message is
that the local firewall is configured improperly.
Just for sake, I used iperf and netcat to send UDP packets and it is working
fine in several ports, so we can rule out firewall issue.
Any thoughts?
Thank you very much.
