Claim 12:
13. A multi-site distributed storage system having a primary storage site with a primary storage cluster and a secondary storage site with a secondary storage cluster, comprising:
a processing resource; and
a non-transitory computer-readable medium coupled to the processing resource, having stored therein instructions, which when executed by the processing resource cause the processing resource to:
maintaining a first operation (Op) Log for a first volume and a second Op Log for a second volume in order to be capable of facilitating resynchronization between a dataset stored on the first volume of the primary storage cluster of the distributed storage system and a mirror copy of the dataset stored on the second volume of the secondary storage cluster of the distributed storage system, wherein changes to the dataset are synchronously replicated to the second volume;
receive an operation associated with a file within the dataset;
determine whether the operation is a modifying operation; and
creating an operation (Op) log entry with one of the first and second Op Logs if the operation is a modifying operation to cause a modification of the file, wherein the Op log entry contains a sequence number assigned to the operation, and wherein the Op log entry is not required to contain data associated with the operation when the operation comprises a write operation.
