Is your feature request related to a problem? Please describe.
Carp can be a challenge to troubleshoot, having a docs article that would explain some common and advanced scenario could help us and others.
Describe the solution you like
- Common and intermediate errors with CARP (e.g. multicast issues, split-brain scenario, flapping interfaces, TX/RX errors etc...)
- Which log files are important
- Which patterns in log files to look out for, common CARP errors and other related errors
- CARP debug logging
- important sysctl values and how to reset them
- viewing and comparing the VIP hashes
- Checking CARP configuration for errors
It does not have to be perfect, it should give an overview of a troubleshooting workflow with the most common errors (on shell). More specific errors can be added later to improve this document.
I want the document to be less like a technical documentation and more like a manual/how-to
