Set up Multiple service-discover Servers
Within a Carbonio Multi-Server installation, it is possible to
install multiple service-discover
servers, provided they are
in odd numbers, e.g., 1, 3, 5 (or even more), because they can
always find a quorum and avoid deadlocks.
Requirements
In order to setup additional service-discover
servers, you need:
having installed and configured package
service-discover-server
on one node (see Section SRV2: Directory Server, LDAP Server, and DB connection)the
/etc/zextras/service-discover/cluster-credentials.tar.gpg
file created in the set up of the first instance of service-discovery
Moreover, as mentioned before, make sure to install an odd number of
service-discover
servers.
Installation
Instructions to install multiple service-discover
servers are
the same for each new server installed, simply repeat the following
procedure on each new server.

# apt install service-discover-server

/etc/zextras/service-discover/cluster-credentials.tar.gpg
