The HA Service doesn’t need SQL backend. Here are some config snippets how it
is working in my environment. Just replace the code between <> with your system
data.

I believe I’ve discovered why my setup doesn’t play. Seems HA feature depends
on using configuration backend (CB) which again requires use of MySQL.
I was hoping HA could have worked using memfile but I guess not.
I am sorry I can’t tell you how to fix your configuration, but I am positive
the HA feature does NOT depend on the configuration backend. HA definitely
works with memfile. This is not the problem.
