I think I found the problem, I used:

```auto
pcs cluster setup test_cluster --start server-2 server-1 --force

```

If I change this value inside `corosync.conf` to the actual IP, both servers are online.

```auto
ring0_addr: server-*

```

The hosts file looks like:

```auto
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 server-2
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.1.112 server-2
192.168.1.111 server-1

```

I noticed this problem with netstat. 😬

```auto
udp 0 127.0.0.1:5405 0.0.0.0:* 0 28920 2809/corosync 

```
