Abstract
One or more techniques and/or computing devices are provided for implementing synchronous replication. For example, a synchronous replication relationship may be established between a local storage controller hosting local storage and a remote storage controller hosting remote storage (e.g., replication may be specified at a file, logical unit number (LUN), or any other level of granularity). Data file operations may be implemented in parallel upon the local storage and the remote storage. Independent metadata file operations may be independently implemented from data file operations upon the local storage, and upon local completion may be remotely implemented upon the remote storage. In-flight data file operations may be drained before dependent metadata file operations are locally implemented upon the local storage, and upon local completion may be remotely implemented upon the remote storage.
