Title: DATA RECOVERY METHOD AND FILE SERVER
Abstract:
Disclosed are a data recovery method and a file server, which relate to the technical field of storage, and can solve the problem in the prior art that when data in a faulty disk are copied to a new disk, file parsing needs to be performed, so the copying speed becomes slow, thereby causing the recovery speed of the faulty disk to be slow. The specific solution is: when data in a faulty disk need to be recovered, a file server creates management metadata in a new disk, the management metadata being management information about the new disk (101); the file server copies a node data block in the faulty disk to the new disk, the node data block comprising a directory data block or a file data block (102); and the file server mounts the node data block copied to the new disk from the faulty disk on the management metadata of the new disk (103).
