我已经安装了一个水桶：
hostname:/ # gcsfuse --implicit-dirs --foreground bucketname /directory
Using mount point: /directory
Opening GCS connection...
WARNING: gcsfuse invoked as root. This will cause all files to be owned by
root. If this is not what you intended, invoke gcsfuse as the user that will
be interacting with the file system.
Opening bucket...
Mounting file system...
File system has been successfully mounted.
然后，在另一个连接中，运行此命令：
hostname:/ # head /directory/subdirectory/file.bak
head: error reading '/directory/subdirectory/file.bak': Input/output error
同时，在带有gcsfuse的第一个shell上，我看到了：
fuse: 2019/06/11 13:23:28.153146 *fuseops.ReadFileOp error: fh.reader.ReadAt: startRead: NewReader: Received unexpected status code 200 instead of HTTP 206
另一方面，树上的目录是完全可遍历的。
编辑：使用--debug_gcs，我发现了这一点：

这似乎不是gcsfuse中的正常权限错误，而是带有-implied-dirs 的东西。有人可以帮忙吗？
