Abstract
A data recovery method includes: by a first data node, obtaining a notification that a second data node fails; and storing specified data to a third data node, recording information of the specified data stored in the third data node in backup information stored in the first data node, and providing a metadata node and other data nodes storing the specified data with the information of the specified data stored in the third data node, where the specified data is data stored in the first and second data nodes. A data recovery method, two data nodes, and a distributed file system are also provided. In embodiments of the present invention, the data recovery is mainly performed among the data nodes, and the metadata node does not need to perform a lot of operations. Therefore, the load of the metadata node is reduced.
