How to change Foglight Management Server from a standalone server to run as a high availability server? (4290492)

How to change Foglight Management Server (FMS) from a standalone server to run as a high availability (HA) server?

Note: The FMS repository must be an external database

As per the HA entry within the 'server.config' (foglight.config on version FMS 5.5.8 and below) file, it states the following:

# If you did not choose HA option at installation time but wish to use HA
# mode afterwards, uncomment the following line, fill in a partition name, and
# start the server using "fmsha" command
#
# foglight.ha.partition.name = "";

So, in summary, all you need to do is remove the # to uncomment the argument, and set a name for the HA partition, for example:
foglight.ha.partition.name = "FMS_HA";

Ensure all nodes, that you wish to use within your HA environment, have the same entry as above. Once that is done, start all intended HA servers using the fmsha command for HA to work accordingly.
