更新2018年10月23日
该指标现在支持 列出网络共享。感谢mihaigalos
更新2016年10月29日
指示器现在具有卸载功能，并且通过引用每个分区的UUID而不是块设备名称（例如）来使别名唯一sda1。查看相关的错误报告
更新，2016年10月8日
该指标现在是2.0版，增加了一些功能并拥有自己的PPA。
要从PPA安装，请在终端中使用以下步骤：
sudo apt-add-repository ppa:udisks-indicator-team/ppasudo bash -c 'apt-get update && apt-get install udisks-indicator'
如发行说明中所述，这些功能包括：
- 菜单条目的图标：每个分区/设备均附有适当的图标。如果设备是USB磁盘，则使用可移动媒体图标；如果它是iso映像，则使用-光盘图标，并且显然硬盘/ SSD分区具有驱动器图标。
- 现在以百分比和人类可读的值（1024的幂）显示使用情况。
- 通过使用情况条以图形方式表示使用情况（非常感谢Mateo Salta的想法）
- 首选项对话框：用户可以关闭每个菜单项中不想看到的某些字段。如果连接了大量分区，这可以使指示器菜单保持干净。（感谢Zacharee的请求）
- 文本间距：使用默认的Ubuntu字体和Monospace字体，文本条目之间的间距很好，以使外观更整洁并增强信息的可读性。
- 如果无法安装分区，则会出现通知气泡
以下是默认Ubuntu图标主题的屏幕截图：
Ubuntu Kylin图标主题
关闭所有可选字段
设计选择和其他想法：
在制定此指标时，我希望获得一种适用于高级和休闲用户的实用程序。我试图解决一些新用户在处理命令行工具时可能遇到的问题。另外，该实用程序努力成为多用途的。
使用“首选项”对话框可以使指示器复杂和/或简单，如用户所愿。这也是一个特定的设计决策，要避免在顶部面板中贴标签，以免占用用户的顶部面板空间过多。另外，该指示器致力于成为一种多功能工具，该工具允许安装分区以及打开其各自的目录。它不仅可以用作磁盘使用实用程序，还可以用作导航实用程序以快速打开目录。
用户也很方便地知道哪个分区驻留在哪个磁盘上，从而避免了通过诸如的命令行实用程序进行安装时的频繁混淆mount。相反，它udisksctl为此目的而使用（以及从UDisks2守护程序中获取信息，从而进行命名）。它唯一不执行的任务是卸载，或者因此包含Open Disks Utility菜单项。
虽然最初我努力使其类似于iStat menulet，但该项目与该目标有所不同-该指示器在设计和目的上都是独一无二的。我希望它将对许多用户有用，并使他们的Ubuntu体验更加愉快。
udisks-indicator（原始答案）
具有Unity桌面的Ubuntu指示器以显示磁盘使用情况
总览
带有Unity的Ubuntu指示器可轻松查看有关已安装分区的信息。它努力在视觉上类似于OS X中的iStat Menu 3菜单。
条目按顺序组织：
- 划分
- 别名（如果由用户设置）
- 分区所属的磁盘驱动器
- 分区的安装点（目录）
- 使用百分比
单击每个分区条目将在默认文件管理器中打开分区的挂载点
“未安装的分区”菜单列出了系统当前未安装的所有分区。单击该子菜单中的任何条目将自动将该分区安装，通常安装到/media/username/drive-id文件夹
该指示器使用系统随附的默认图标，因此当您使用Unity Tweak Tool或其他方法更改图标主题时，该图标应在更改
注意：如果要同时添加多个别名，而不是通过“ Make Alias”选项一个接一个地添加，可以通过编辑~/.partition_aliases.json配置文件来添加。格式如下：
{
"sda1": "Alias 1",
"sda2": "Alias 2",
"sdb1": "Alias 3"
}
安装
易于安装的PPA即将推出。。。
同时，这是替代步骤：
cd /tmpwget https://github.com/SergKolo/udisks-indicator/archive/master.zipunzip master.zipsudo install udisks-indicator-master/udisks-indicator /usr/bin/udisks-indicatorsudo install udisks-indicator-master/udisks-indicator.desktop /usr/share/applications/udisks-indicator.desktop
所有这些步骤都可以放入一个不错的安装脚本中：
#!/bin/bash
cd /tmp
rm master.zip*
wget https://github.com/SergKolo/udisks-indicator/archive/master.zip
unzip master.zip
install udisks-indicator-master/udisks-indicator /usr/bin/udisks-indicator
install udisks-indicator-master/udisks-indicator.desktop /usr/share/applications/udisks-indicator.desktop

附加信息：
Ubuntu Mate 16.04测试：
侏儒用户需要扩展（KStatusNotifierItem / AppIndicator支持）以使指标正常运行：
/dev/sdb1并在其旁边使用它？以百分比还是实际的千兆字节为单位？
