Abstract
Techniques are provided for managing replication journals in a distributed replication system. A data replication system assigns an associated replication journal volume to each replication component operating on a storage node. Each replication component is configured to handle a portion of a replication workload which is distributed among the replication components, and to write journal data in the associated replication journal volume of the replication component. The data replication system performs a recovery process in response to detecting a failed replication component. The recovery process includes designating at least one replication component as a recovery replication component, designating the associated replication journal volume of the failed replication component as a recovery journal volume, and assigning the recovery journal volume to the recovery replication component to enable the recovery replication component to recover journal data in the recovery journal volume.
