Hobbit newbie from BB: differences and what may Ilose from migrating?

Have you considered setting up some kind of Heartbeat or VRRP system ?
At my lab, we use VRRP to share one IP between a master DNS and a secondary DNS which takes over if the primary fails (we have the same system for our web site and our mail server).
If the slave cannot contact the master, it takes over the 'public' IP, and can start some services, like bind or dhcpd for example.
There seems to be the same kind of possibilities with Heartbeat, but I haven t looked into it yet.
You could maybe set up your "b" site to start sending notifications in the event that site "a" is unreachable ?

We have 2 separate data centers, and while there are bb servers in both data centers monitoring the hosts on both sides, only side "a" does notifications. When side "b" can not reach side "a", then side "b" "fails over" and takes on the notification tasks, until side "a" becomes reachable again. There's nothing like that in hobbit yet, but if there were, we'd be able to make the switch.I won't say it is being worked on, but it is definitely on my agenda. My own setup is identical to yours, except that we have a procedure for doing the failover from site "a" to site "b" manually. I've done some planning for how to implement an active/passive cluster-like setup in Hobbit, so ... it's coming. Regards, Henrik
