Abstract
Aspects of the subject matter described herein relate to shutdown recovery for resource replication systems. In aspects, a mechanism is described in which a machine having replicated data thereon can recover from a dirty shutdown. First, the machine determines whether a dirty shutdown has occurred. If so, the machine automatically performs shutdown recovery by causing resource metadata stored by the machine to be consistent with resource data stored by the machine. This may involve fixing the resource metadata for updates to the resource data that were not flushed to disk or may involve deleting the resource metadata and restoring it from another machine replicating the data.
