Abstract
A method for a node to become a member of a cluster includes, when the node is in an initialization state, refraining from starting any service for the cluster, rejecting any reconfiguration request from a coordinator of the cluster, and determining if a local copy of a member list is out-of-date. When the local member list is up-to-date, the method includes advancing to an observer state or a participant state depending on if the node is in the member list. When the local copy of the member list is out-of-date, the method includes waiting to receive the member list, updating the local member list to be equal to the member list, persisting the local member list, recording the local member list as up-to-date, and advancing to an observer state or a participant state depending if the node is in the member list.
