Are you sure you are running corosync on that machine as root AND you
really turned of selinux?

Yount, William D napsal(a):
I am following the guide posted here: http://www.clusterlabs.org/doc/en-US/Pacemaker/1.1/html/Clusters_from_Scratch/
I have two servers with dual NICS:
Server 1
NIC-A: 10.89.99.31
NIC-B: 192.168.1.5
Server 2
NIC-A: 10.89.99.32
NIC-B: 192.168.1.10
I want to use NIC-B on both machines to carry corosync traffic. I got down to this section:
1. export ais_port=4000
2. export ais_mcast=226.94.1.1
3. export ais_addr=`ip addr | grep "inet" | tail -n 1 | awk '{print $4}' | sed s/255/0/`
4. env | grep ais_ais_mcast=226.94.1.1
The last command did not produce any output, so I edited the corosync.conf file manually. I have attached a copy of the file as it appears on both servers. I am able to start corosync up on Server 1 with no problems. On Server 2, I am getting the errors below:
Jun 7 01:06:48 KNTCLFS002 corosync[2452]: [TOTEM ] Initializing transport (UDP/IP Multicast).

I have made sure that iptables is turned off and selinux is set to permissive. When I run the command 'corosync-blackbox' I get this:
rec=[1056] Log Message=sendmsg(mcast) failed (non-critical): Socket operation on non-socket (88)

I can ping each machine from the other one. Any help will be greatly appreciated.
Thanks,
William
