Editing DRBD Reactor Promoter Plugin Configurations on Running Systems

If you need to edit a DRBD Reactor promoter plugin configuration that currently manages high availability services in your cluster, this knowledge base article guides you through the process.

You can also adapt the workflow in the article if you need to perform system maintenance on nodes in your cluster. In this case, forego the editing the configuration file parts of the process, and rather than disabling the two inactive nodes at once, disable just one node at a time when you need to do system maintenance, for example, if you need to update memory or an application.
