日常巡检时发现项目系统docker服务运行异常,无法使用docker ps等命令,正常启动docker服务夯住。通过开启debug模式,发现进程卡在activateDeviceIfNeeded处。

问题排查思路

docker服务在低版本内核时默认使用devicemapper,因能力有限,无法排查到具体因为什么原因引起的。故需要更改storage-driveroverlay

升级内核

内核升级成功后需要重启系统。

[root@localhost ~]# yum -y update kernel
[root@localhost ~]# reboot
修改daemon

编辑/etc/docker/daemon.json文件并添加或修改storage-driver内容。

{
    "log-driver": "json-file",
    "log-opts":
    {
        "max-size": "100m"
    },
    "storage-driver": "overlay",
    "registry-mirrors":
    [
        "http://hub-mirror.c.163.com"
    ]
}

修改完成后重启docker即可。

辅助命令
  • dmsetup ls:查看虚拟设备
  • dmsetup mknodes: 加载全部虚拟设备至/dev/mapper/
  • dmsetup remove_all: 移除所有虚拟设备
END
