给出错误消息“不支持的图形驱动程序:btrfs"；在SLES中，尝试进行Kubeadm初始化时 [英] Giving error saying "unsupported graph driver: btrfs" in SLES when try to Kubeadm init

问题描述

我尝试在SLES上安装Kuberneties集群.但是当我使用下面的命令执行Kubeadm初始化时，会给出给定的错误.

I try to install Kuberneties cluster on SLES. But When I do Kubeadm init using below command it gives given error.

Kubeadm初始化

Kubeadm init

kubeadm init  --pod-network-cidr=10.244.0.0/16 --kubernetes-version=1.15.3

错误

error execution phase preflight: [preflight] Some fatal errors occurred:
        [ERROR SystemVerification]: unsupported graph driver: btrfs
    [preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...`

在SLES中，默认文件系统为btrfs.因此，根据官方Docker文档获取适用于SLES的Docker EE 在/etc/docker/daemon.json

In SLES default file system is btrfs. So as per the official docker documentation Get Docker EE for SLES I add below in /etc/docker/daemon.json

{
  "storage-driver": "btrfs"
}

那怎么了?需要您的帮助.

So what would be wrong? Need your kind assistance.

推荐答案

这是问题所在.

SLES默认使用btrfs.该文件系统不支持docker"overlay"驱动程序，因此在/var/lib/docker中使用etx4是明智的.

SLES uses btrfs by default. The docker "overlay" driver is not supported with this file-system, so it is sensible to use etx4 in /var/lib/docker.

即使我们告诉Docker有关BTRFS的信息:

Even if we tell Docker about BTRFS :

https://docs.docker.com/storage/storagedriver/btrfs-驱动程序/

Kubeadm仍然会抱怨.

Kubeadm will still complain.

因此请在/var/lib/docker中使用etx4.

So use use etx4 in /var/lib/docker.
