HA setup for Management server

[Felipe Arturo Polanco <fe...@gmail.com>]

Hi,

I followed the guide on the documentation for the Multi node Management
servers, they are up and running but when the first provisioned MGMT server
goes down, the agents in the SystemVMs goes offline.

I checked the scripts in the systemVM and found that the agent is tied to
the IP of the first provisioned management server, thus when it goes down
the agent can't communicate.

Has anyone stumbled on this problem and found a solution for a true HA
setup?

Thanks,

Thanks Rafael, right in the spot, it's working now with a Virtual IP I put
between mgmt nodes.

I think that script uses the parameter “host” to configure those scripts.
You should then configure the “host” parameter as a URL to a load balancer
which can balance/provide HA for features needed by system VMs from MSs.
You can use HA proxy to load balance/provide HA for those service ports,
which are not 443, 80, 8080 and other common ones used for HTTP.
