Provided are a distributed file system and a method of replacing cache data in a distributed file system capable of replacing cache data based on the degree of network instability between a server and a client. The method includes monitoring network instability between the first apparatus and the second apparatus, determining whether an empty space exists in a storage space of the second apparatus if the second apparatus needs data of the first apparatus, if an empty space does not exist in the storage space, deleting at least one cache data item already stored in the second apparatus according to the monitored network instability, and storing data obtained from the first apparatus in the empty space generated by deleting the cache data.
