Question

我在kubectl describe nodes nodename中遇到此错误。我刚刚进行了谷歌搜索，但没有找到任何有用的信息，这意味着什么。

Failed to update Node Allocatable Limits "": failed to set supported cgroup subsystems for cgroup : Failed to set config for supported subsystems : failed to write 3783778304 to memory.limit_in_bytes: write /rootfs/sys/fs/cgroup/memory/memory.limit_in_bytes: invalid argument

我是否需要使用sysctl更改某些内核设置？

[iahmad@lxplus000 ~]$ kubectl --version
Kubernetes v1.5.2
[iahmad@lxplus000 ~]$

Answer 1

这取决于kubectl/kubernetes版本：kubernetes issue 42701

中看到（并修复了）

1.6应该已修补。如果这不是同一个错误，则在issue 29166：

中也会看到错误消息

我忘了在创建新VM后忘记激活disk.uuid！

kubectl描述节点，报告一些错误
