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, wherein the converting takes place in both 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, wherein the removing includes physically deleting and disconnecting 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
A non-distruptive migration of a native volume from a source server to a destination server performed by a file switch involves converting the source native volume to a native with metadata volume. The native with metadata volume is converted to a mirrored native with metadata volume including the source server and the destination server. The destination server includes a mirror copy of the native with metadata volume. The source server is removed from the mirrored native with metadata volume. The mirror copy of the native with metadata volume on the destination server is converted 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; a processor coupled to the network interface; and a memory coupled to the processor, wherein the processor is configured to execute programmed instructions stored in the memory comprising; converting the source native volume to a native with metadata volume using a local file system managed by the file switch; converting , the native with metadata volume to a mirrored native with metadata volume, wherein the converting takes place in both 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, wherein the removing includes physically deleting and disconnecting 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A non-transitory computer readable medium having stored thereon instructions 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, comprising machine executable code which when executed by at least one processor, causes the processor to perform steps comprising:
-
converting the source native volume to a native with metadata volume using a local file system; converting the native with metadata volume to a mirrored native with metadata volume, wherein the converting takes place in both 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, wherein the removing includes physically deleting and disconnecting 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. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
