16. A device for managing segments in a distributed-file system implemented by a plurality of file servers, the device comprising:
-
a communication interface configured to communicate with the file servers; and
a processor coupled to the communication interface and configured to;
determine a segment of the distributed-file system controlled by a first file server for which control is to be migrated;
select a second file server, that is different from the first file server, to take control of the segment; and
send indicia to the file servers to effect moving of control of the segment from the first file server to the second file server. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
