Pseudo-HA on 2 or 3 containers without clustering. Possible?

[dominikp]

I have 2 LXC containers which are basically a twins (except MAC and IP). They are openvpn servers. Sometimes one of them just stops (entire lxc container). This happens once for few months.
What i plan to make are some kind of watcher scripts (bash) placed on each other which will ping themselves every 5mins or so. If one of them dies then second should somehow try to start another one. Or maybe it would be easier to place them on host.

Anyway, is it good approach? Or are there better solutions? I dont want ( i cant) to create cluster with second machine.

PS. Im aware that it doesnt provide ha on service lvl, but for now it would be sufficient solution.

You could use something as HAproxy ,or similar thing with floatingIP.

Well dont want only to switch between servers. This i can do on clients side (manually or automatically). But i would rather try to revive the ones which are down.
//EDIT
OK i found option in HA section. I think problem is solved.
