Non-Disruptive File Migration
First Claim
1. In a switched file system having a file switch in communication with a plurality of file servers including at least a source server and a destination server, where the source server manages a source native volume, a method for non-disruptive migration of the native volume from the source server to the destination server, the method comprising:
- converting, by the file switch, the source native volume to a native with metadata volume using a local file system managed by the file switch;
converting, by the file switch, the native with metadata volume to a mirrored native with metadata volume including the source server and the destination server, the destination server including a mirror copy of the native with metadata volume;
removing, by the file switch, the source server from the mirrored native with metadata volume; and
converting, by the file switch, the mirror copy of the native with metadata volume on the destination server to a destination native volume on the destination server.

Abstract
Non-disruptive migration of the native volume from the source server to the destination server performed by a file switch involves converting the source native volume to a native with metadata volume; converting the native with metadata volume to a mirrored native with metadata volume including the source server and the destination server, the destination server including a mirror copy of the native with metadata volume; removing the source server from the mirrored native with metadata volume; and converting the mirror copy of the native with metadata volume on the destination server to a destination native volume on the destination server.

10. A file switch for non-disruptive file migration in a switched file system having a plurality of file servers including at least a source server and a destination server, where the source server manages a source native volume, the file switch comprising:
-
a network interface for communication with the file servers; and a processor coupled to the network interface and configured to convert the source native volume to a native with metadata volume using a local file system managed by the file switch;
convert the native with metadata volume to a mirrored native with metadata volume including the source server and the destination server, the destination server including a mirror copy of the native with metadata volume;
remove the source server from the mirrored native with metadata volume; and
convert the mirror copy of the native with metadata volume on the destination server to a destination native volume on the destination server. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
