 ### Change by `volume.move`
 `volume.move` in `weed shell` can be used to move across volume servers:
 ```
-volume.move -source <source volume server host:port> -target <target volume server host:port> -volumeId <volume id> -disk [hdd|ssd]
+volume.move -source <source volume server host:port> -target <target volume server host:port> -volumeId <volume id> -disk [hdd|ssd|<tag>]
 ```
