Abstract
Snapshots are created on replicated storage systems R1 and R2 in a manner resulting in identical snapshots being generated on R1 and R2. In response to an instruction to create a snapshot on a storage system (R1 and/or R2), command-phase write operations (CWOs) are held and data-phase write operations (DWOs) are completed on the storage system before the snapshot is created. Determining that DWOs includes querying processes, and using information, available on the storage system, by which a state of a write operation—e.g., whether the write operation is a DWO and when the DWO completes—may be determined. A CWO queue may be maintained on the storage system for tracking the status of CWOs. A DWO queue may be maintained on the storage system for tracking DWOs, to determine DWOs when the snapshot is created, and track their processing, including when they are completed.
