[olug] Fails Over, but does Not Fail Back

[Rob Townley]

tldr; Systems that reliably fail over to redundant system, but absolutely
refuses to revert back to primary system.

Looking for general guidelines on systems (primarily networking) to
troubleshoot the fail back to primary pathway.

The failover happens reliably.   The   problem is  when the primary comes
back up, actually reverting back, aka “Failing Back” to the primary path.

Have experienced this failure to fail back too many times across a variety
of equipment and systems.  Looking for general guidelines.  What do noobs
usually miss?

Also, is it a common problem or just me?
