Server chronicles - HA temporary server (UPDATED)

Among many other services, my server hosts some HA services to control my X10 lights and some operations.
Since my glorious server need to be rebuilt and as usual I don't have time, I needed to find a quick solution for my X10 server.
I decided to use a spare Raspberry I have around and create a temporary HA server, until the main one will be restored.

Server chronicles - planning - UPDATE !

Well, it was matter of time.  

An hard drive in the server died during the latest thunderstorm.
It is time to do some maintenance to the system, very probably rebuild it from scratch, a good time to reinstall only what is really needed and  a full upgrade to the latest version of Linux.
After 7 years of continue service 24/7 I would say it is time 😁
