Adding a secondary management server
Dear colleagues,
Would you be so kind as to share your experience of running multiple servers?
I have 2 management servers, they have different IP-addresses (x.x.x.1, x.x.x.2) and there are also a common IP-address (x.x.x.3) that is being provided by a load-balancer (haproxy). Also I have some hosts and some system VMs, they all connect to x.x.x.1, because x.x.x.1 was the management-server who was used to set-up the zone.
It's easy to let the hosts know that they need to connect to x.x.x.3, as this parameter is being set in agent.properties, but where to change it in the system VMs? Grep haven't found x.x.x.1 anywhere but the log-files. Moreover, if I destroy and create the system VMs, they'll keep establishing connections to x.x.x.1. How to change their behaviour?
Had I add "-m x.x.x.3" when I was running cloudstack-setup-database to prevent that? It's a new setup, so it's still okay to reset it. :)
Thanks to all for sharing clues and hints!

Oh, yes, how could I forget the "host" parameter??
Thank you very much!

Hello Vlamdir,
you need to change settings in global settings, Go to your global settings
in your cloudstack and search for "host", i m sure it will be your 1st
management ip( x.x.x.1) , so remove this out and put the virtual ip ( Load
balancer IP- x.x.x.3 ) in host section and then restart all cloudstack
services on both of yours management server.
