We have sent an upstream patch[1] that enhances the list command by showing used space in case of 'gluster v quota <VOLNAME> list <path>' and shows 'dir_count,file_count' with gluster v quota <VOLNAME> list-objects <path>' command even when quota limit is not set(But quota/inode-quota should be configured for the first time).
