Incus Cluster Requirements

Hi everyone,
Is it possible to make a cluster with 2 hosts and if possible what can be the incus cluster requirements /settings for it?
Regards.

It’s possible, but very much not recommended.

You need 3 servers for the database to be highly available.
A cluster of 2 will be less reliable than a standalone server as the loss of either server can doom the entire cluster.

Thanks Stephane.

Sorry for open this thread again, When I initialize hosts separately in incus, can I add those hosts to cluster later on? How do I convert those hosts to make a cluster?
Regards.

An initial server can be converted from standalone to the first server in the cluster.
Any server after that must be completely empty when it’s joined to the cluster.
