Methods and systems for cursor remirroring are disclosed. A mirroring process is initiated for a plurality of chunks stored by a master node. The mirroring process comprises visiting a sequence of one or more of the chunks and, for at least some of the chunks, copying chunk data or metadata to a slave node. During the initiated mirroring process, a request is received for a write operation on one of the chunks stored by the master node. If the chunk in the request has been visited in the mirroring process, the write operation is performed on the master node and on the slave node. If the chunk in the request has not been visited, the write operation is performed on the master node and postponed on the slave node until the chunk in the request has been visited in the mirroring process.
