Abstract
A mechanism is provided in a data processing system for unobtrusive failover in a clustered file system. A node in the clustered file system periodically monitors publicized resource events from a cluster manager in the clustered file system for a triggering event that triggers a grace period. Responsive to detecting a triggering event, the node enters a grace period without restarting. During the grace period, the node processes a state request from a first client.
