We need solution for something like VIP for our MySQL servers (for example)
with auto migration when something go wrong. If you have a better solution
– please suggest.
Talking about dynamic IP addresses: it is not important for us. After boot
(not every day) we reconfigure cluster using maintenance mode in the
pacemaker.
