Wow! What a shame! How could I miss it... So you're absolutely right,
thanks: that was the cause, an entry in /etc/hosts. On some machines I
removed it manually, but on others - didn't. Now I do it automatically
by sed -i -r "/^.*[[:space:]]$host([[:space:]]|\$)/d" /etc/hosts in the
initialization script.
I apologize for the mess.
So now I have only one place in corosync.conf where I need to specify a
plain IP address for UDPu: totem.interface.bindnetaddr. If I specify
0.0.0.0 there, I'm having a message "Service engine 'corosync_quorum'
failed to load for reason 'configuration error: nodelist or
quorum.expected_votes must be configured!'" in the logs (BTW it does not
say that I mistaked in bindnetaddr). Is there a way to completely untie
from IP addresses?
