Hi!

I have 2 servers with redundant links: eth0 + eth1

corosync (1.2.1-4 Debian package) is configured to use 2 interfaces:
ring0 uses eth0, ring1 uses eth1. rrp_mode: active


If I unplug eth1, then corosync detects that (corosync-cfgtool -s on
both servers reports ring1 as faulty).

However if I unplug eth0, then corosync-cfgtool -s on both servers still
reports ring0 as "no faults". (However pacemaker detects that the other
node is offline whereas itself is online.) If I reverse the config so
that ring0 uses eth1 and ring1 uses eth0, then the same problem happens
with eth1. Thus, ring0 is always "no faults", even if the Ethernet cable
is unplugged.

Question 1: Is this a bug/feature/know problem that ring0 is always
reported as "no faults"? Is there a solution/workaround to have proper
ring status?


Next thing is, that if I call "corosync-cfgtool -r" while ring1 is
faulty, then ring1 status will become "no faults" although it is still
unplugged - which IMO is another bug. Any reason for this?


Would updating to 1.3.0-3 from Debian backports improve the situation?

Thanks
Klaus
