AWS Greengrass守护程序无法在Amazon Linux中启动

Question

关于亚马逊网络服务(http://docs.aws.amazon.com/greengrass/latest/developerguide/start-core.html)的文档(遵循所有先决条件)，我正在尝试在Amazon Linux上设置AWS Greengrass核心。

我在启动Greengrass核心守护进程时收到以下错误

 ./greengrassd start

Found cgroup subsystem: net_prio
Found cgroup subsystem: hugetlb
Found cgroup subsystem: pids

Starting greengrass daemon
Greengrass daemon 23933 failed to start
Failed to create overlay fs for container rootfs no such file or directory

我找不到任何解决这个问题的方法，我被困在这个过程中。如果你们中有谁能帮我解决的话会更有帮助。

您是否尝试过使用sudo执行./greengrassd start命令？

当我省略sudo时，我可能会出现一个错误，指出需要使用sudo来运行此命令。

sudo ./greengrassd start
