## 'mv_avs_dir' which can be used to change the data directory.
##
## You just specify the current directory and the destination directory,
## and you need to modify the leo_storage configuration, 'obj_containers.path '
## before re-launching the LeoStorage node.
##
## Note: You need to stop a target LeoStorage node before executing 'mv_avs_dir'.
