Abstract
A first storage server of the file system receives a request to perform an operation on the data file. The operation is to be performed on a first replica of the data file stored at the first storage server and a second replica of the data file stored at a second storage server of the file system. The first storage server configures first metadata associated with a first index file to indicate that the operation is to be performed on a first portion of the first replica. The first storage server determines the second replica is an outdated state indicating that the operation on the second replica has not been performed by the second storage server. In response to the second replica being in the outdated state, updating a first portion of the second replica identified in view of the first metadata and corresponding to the first portion of the first replica.
