[Kea-users] High Availability

We, too, hope to attain high availability by

  *   using Pacemaker/Corosync to monitor Kea (fronted with a floating IP address since we deal exclusively with dhcrelay)
  *   using replicated postgres databases for leases

Note the complete lack of HA with respect to configuration files. We are hoping that the configuration can be stored in the database in a future release.

Hello,

I understood that Kea still does not have failover or any other type of high availability (I have version 1.1.0 and use memfile).

Case 1: If I use only static lease (reservations) and keep two servers with the same configuration file, would it work as high availability ?.

Case 2: If I use a pool on each server, would it be a way of high availability? :
server1 = {"pool": "192.168.0.50 - 192.168.0.100"}
server2 = {"pool": "192.168.0.101 - 192.168.0.200"}

Thanks,
