Peoples? If you want to do failover with puppet servers and you are using environments, there's a major gotcha that I really should add to that page... If a puppet client connects to server A, downloads the compiled manifest, and then starts requesting files via the puppet:/// protocol, and in the middle of all these short lived requests the server switches over to Server B, that server doesn't necessarily know what environment the client should be using, as that is stored in a file on the server. The only feasible solution is to somehow share those state files between servers. This may or may not be feasible in your environment (no pun intended...) -- Nigel Kersten Systems Administrator Tech Lead - MacOps --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.
