RE: [hobbit] failover?

["Mike Rowell" <Mike.Rowell (at) Rightmove.co.uk>]

I have a basic ext script that does a basic check to make sure bbd is up
and running on the primary server, if it is not then it fails over to
the secondary server.  As I say it is basic but it does what I need it
to.

The process is as follows;

Secondary Run's hobbit-redundant check Via ext every 5 minutes
If Primary Server Up then do nothing
Else If Primary Server down then copy in place hobbit-alerts.cfg.live 

This is reliant on data being sent to both servers (so having a proxy
sending to both servers or the clients configured to send data to both
bb servers.

Regards,

Mike Rowell

Hi
I use two independent Hobbit servers; each client reports to both
servers. The question is how to synchronize the two
servers after an outage of a server.
