Subject Re: Failover, how does it work?
Date Tue, 29 Mar 2011 12:22:47 GMT
To send email or notification we are thinking in use a monitorization tool
like nagios or something more light...

About the manual restart, i think that you could take a look about
linux-heartbeat v2, you could configure services to monitorize and make
petitions.


One more question, If we have a cluster, if the master goes down, all
messages goes to the slave, but, if we start the master again, all messages
will send to the master again?
