I have DNS roundrobin on 2 virtual IP in front of service. (Among others the service tested was: apache, nginx, varnish, postfix, … It really does not matter. Let's call it just service.)
I have corosync config where on two nodes service is running (as a clone with
max=2 max-node=1) and each node has one of 2 virtual IP.
- In case of node failure: Corosync stop, standby mode - other node takes over IP.
- In case of stopping service: Cluster brings it up.
- In case of destroying config of the service: Cluster cannot start it and it remains stopped/errored but the virtual IP remains.
When the cluster was active/passive there waw no clone. Primitive service was in group with IP and in case of failure also virt IP wasn't started.
I cannot group clone.
How do I solve this?
Please note that it seems to have nothing with ordering, which works just fine.
