提取泊坞窗图像时提取文件失败答案

【问题标题】：Failure extracting files when PULLing docker image提取泊坞窗图像时提取文件失败
【发布时间】：2020-04-27 00:39:01
【问题描述】：

我正在尝试提取并运行一个非常简单的 python 应用程序以进行测试，但我面临以下问题。我在其中创建 docker 映像的服务器是 System Z 上的 Linux，具有相同的架构和相同的 Linux 发行版 - 我想提取的服务器的 SLES 12.5。

/usr 大小为 30 GB 可用空间，因此不会是实际空间不足。

请问有什么想法吗？

inode 利用率似乎不错：

谢谢大家，我想知道“覆盖”docker 文件系统。有趣！
