Intro

Chef High Availability: Backend Cluster and its not so common problems list.

Notes:

• In my case, Chef HA setup is entirely on AWS but this can be translated to other vendors too
• chef-backend-ctl commands are for backend nodes
• chef-server-ctl commands are for frontend nodes

Index

• Nodes hostname
