15.11. Node Maintenance

It is sometimes necessary to shutdown or reboot a node to do maintenance tasks, such as to replace hardware, or simply to install a new kernel image. This is also true when using the HA stack. The behaviour of the HA stack during a shutdown can be configured.

Below you will find a description of the different HA policies for a node shutdown. Currently Conditional is the default due to backward compatibility. Some users may find that Migrate behaves more as expected.
