Multiple Carbonio Mesh servers can be installed within a Carbonio CE Multi-Server installation, provided they are in odd numbers, e.g., 1, 3, 5 (or even more), so they can always find a quorum and prevent deadlocks.

Requirements

You will need the following items to set up more Carbonio Mesh servers:

• installation and configuration of package service-discover-server on one node (see Section SRV2: MTA, Proxy, and User Management)
• the /etc/zextras/service-discover/cluster-credentials.tar.gpg file produced during the initial setup of service-discovery

Furthermore, as previously said, install an odd number of Carbonio Mesh servers.
