Maintaining timestamp parity of objects with alternate data streams during transition phase to synchronous state

Abstract

Techniques are provided for maintaining timestamp parity during a transition replay phase to a synchronous state. During a transition logging phase where metadata operations executed by a primary node are logged into a metadata log and regions modified by data operations executed by the primary node are tracked within a dirty region log, a close stream operation to close a stream associated with a basefile of the primary node is identified. A determination is made as to whether the dirty region log comprises an entry for the stream indicating that a write data operation previously modified the stream. In an example, in response to the dirty region log comprising the entry, an indicator is set to specify that the stream was deleted by the close stream operation. In another example, a modify timestamp of the basefile is logged into the metadata log for subsequent replication to the secondary node.
