2 corosync nodes not online together (one offline, one online)
May be you need to switch to unicast from multicast communication.
Try something like this in your corosync.conf:
totem {
version: 2
secauth: off
interface {
member {
memberaddr: 172.16.0.1
}
member {
memberaddr: 172.16.0.2
}
ringnumber: 0
bindnetaddr: 172.16.0.0
mcastport: 5405
}
transport: udpu
}

I am currently trying to set up corosync based on this tutorial:
However, I am not able to get my 2 nodes connected.
I have 2 nodes:
data-master with IP address LAN: 10.0.0.122, Crossover: 172.16.0.1 data-slave with IP address LAN: 10.0.0.123, Crossover: 172.16.0.2
And this is my /etc/corosync/corosync.conf (exactly same as the tutorial):
compatibility: whitetank
totem { version: 2 secauth: off threads: 0 interface { ringnumber: 0 bindnetaddr: 10.0.0.0 mcastaddr: 226.94.1.1 mcastport: 4000 } } logging { fileline: off to_stderr: yes to_logfile: yes to_syslog: yes logfile: /tmp/corosync.log debug: off timestamp: on logger_subsys { subsys: AMF debug: off } } amf { mode: disabled } aisexec { user: root group: root } service { # Load the Pacemaker Cluster Resource Manager name: pacemaker ver: 0 }
I am able to start the openais service successfully. But, when I checking with
crm_mon -1
on both nodes, they have different result:Node 1 (data-master)

Node 2 (data-slave)

Online: [ data-slave ] OFFLINE: [ data-master ]
What I expect is to get both nodes online together:
Online: [ data-master data-slave ]
Can you guys help me out what exactly I missed?
My platform: VirtualBox, both Nodes are using SLES 11 SP3 with HA-Extension, both Guest IP Address for LAN is bridged, the Crossover is internal network mode.
Thanks!
