A method for defragmenting volumes in a mirrored system. The method includes determining that a defragmentation process has been performed on a second server. The method further includes storing a before and after mapping of a second set of tracks, wherein the before and after mapping includes information identifying at least one track of the second set of tracks and a corresponding first location of the respective track before the performing of the defragmentation process and a second location of the respective track after the performing of the defragmentation process and sending an indication to a first server to relocate at least one track of a first set of tracks on the first server from a first location on the first server to a second location on the first server according to the stored before and after mapping of the corresponding second set of tracks on the second server.
