Hi all. I have two nodes taken different places. They are connected together on a network. So, i have a service, it works on one of nodes and when the node is unavailable the service should will be launched on other node.
Solution: rhel cluster, keepalive, hearbeat...may be Carp
but what if the channel in between nodes will break and servers remain to work...split brain?
And looking ahead may be will need to transfer service but with different addresses(same config but diff network ip)
If somebody worked with similar tasks prompt where to look please!!
