我突然经历了没有磁盘空间Ubuntu 16.04 上的 BOINC 出现问题。我对 Linux 还不太熟悉，所以我很难弄清楚原因。
在 BOINC 首选项中，我允许使用 100 GB 的磁盘空间，但根据 /var/lib/boinc-client 文件夹属性，只使用了 9 GB。
以下是一些输出：

答案1
好的，我找到了解决问题的方法，尽管我不知道我是否完全理解为什么会发生这种情况，或者为什么我无法获得准确的信息来诊断它。
事实证明，我的 BOINC 文件夹中的 ClimatePrediction.net 文件夹中充满了 100 多 GB 的旧工作单元和崩溃的工作单元。这也阻止了任何其他项目任务的下载。我并不想在那堆工作单元中寻找并保存它们，所以我只是重置了项目，现在一切都恢复正常了。
我最初从 Cairo-Dock 打开 Nautilus，右键单击 BOINC 文件夹并选择属性。它告诉我已使用 9 GB 空间，还有 100 + GB 可用空间。但是，当我想到在终端中使用“gksudo nautilus”打开 Nautilus 时，我得到了不同的结果，并能够查明问题所在。我不明白为什么它会有什么不同，但似乎确实如此。
我应该补充一点，为了我自己的辩护，我周日晚上在当地一家医院的急诊室度过，只睡了一两个小时 - 而且我还没有补觉。
干杯!
