No, I meant that if you pass a domain name in ring0_addr, there are no<br>
errors in logs, corosync even seems to find nodes (based on its logs), And<br>
crm_node -l shows them, but in practice nothing really works. A verbose<br>
error message would be very helpful in such case.<br>

This sounds weird. Are you sure that DNS names really maps to correct IP address? In logs there should be something like "adding new UDPU member {IP_ADDRESS}".<br>

Oh, seems I've found the solution! At least two mistakes was in my<br>
corosync.conf (BTW logs did not say about any errors, so my conclusion is<br>
based on my experiments only).<br>

1. nodelist.node MUST contain only IP addresses. No hostnames! They<br>

do not work, "crm status" shows no nodes. And no warnings are in logs<br>

You can add name like this:<br>
<br>
nodelist {<br>
node {<br>
ring0_addr: <public-ip-address-of-the-<u></u>first-machine><br>
name: node1<br>
}<br>
node {<br>
ring0_addr: <public-ip-address-of-the-<u></u>second-machine><br>
name: node2<br>
}<br>
}<br>
<br>
I used it on Ubuntu Trusty with udpu.<br>
<br>
