Hello Steven,

My setup

10.10.10.1 primary server -----EoIP tunnel vpn ipsec ----- dr server 10.10.10.2

On both servers is 2 interfaces eth0 which default gw out and eth1 where corosync live.

Iptables:

-A INPUT -i eth1 -p udp -m state --state NEW -m udp --dport 5404:5407

-A INPUT -i eth1 -m pkttype --pkt-type multicast

-A INPUT -i eth1 -p igmp

Corosync.conf

totem {
        version: 2
        token: 160
        token_retransmits_before_loss_const: 3
        join: 250
        consensus: 300
        vsftype: none
        max_messages: 20
        threads: 0
        nodeid: 2
        rrp_mode: active
        interface {
                ringnumber: 0
                bindnetaddr: 10.10.10.0
                mcastaddr: 226.94.1.1
                mcastport: 5405
        }
}

Join message

[root@eusipgw01 ~]# corosync-objctl | grep member
runtime.totem.pg.mrp.srp.members.2.ip=r(0) ip(10.10.10.2)
runtime.totem.pg.mrp.srp.members.2.join_count=1
runtime.totem.pg.mrp.srp.members.2.status=joined
runtime.totem.pg.mrp.srp.members.1.ip=r(0) ip(10.10.10.1)
runtime.totem.pg.mrp.srp.members.1.join_count=254
runtime.totem.pg.mrp.srp.members.1.status=joined

Is it possible that ping sends out of wrong interface ?

Slava.

Hello Everyone,

Corosync run on box  with 2 Ethernet interfaces.

I am getting this message

CPG mcast failed (6)

Any information thank you in advance.

https://github.com/corosync/corosync/blob/master/include/corosync/corotypes.h#L84

This can occur because:
a) firewall is enabled - there should be something in the logs telling you to properly configure the firewall
b) a config change is in progress - this is a normal response, and you should try the request again
c) a bug in the synchronization code is resulting in a blocked unsynced cluster

c is very unlikely at this point.

2 ethernet interfaces = rrp mode, bonding, or something else?

Digimer needs moar infos :)
