由于"卷存储元数据库:超时",Docker无法启动

Question

我已经按照Docker CE for CentOS的安装说明进行操作.最初这很有效.在某些时候系统重新启动,现在启动Docker失败.欣赏专家对这件事的看法......

systemctl start docker 生产:

docker.service的作业失败,因为控制进程退出并显示错误代码.有关详细信息,请参阅"systemctl status docker.service"和"journalctl -xe".

systemctl status docker.service 生产:

Answer 1

从这里:https://github.com/moby/moby/issues/22507

我跑了:

ps axf | grep docker | grep -v grep | awk '{print "kill -9 " $1}' | sudo sh 

然后我可以使用以下命令重启docker:

sudo systemctl start docker

Answer 2

步骤1：systemctl status docker（如果docker正在运行）停止docker。

第2步：systemctl停止docker。

步骤3：dockerd

Answer 3

我在从生产机器复制卷时收到此消息，最终覆盖metadata.db内部/var/lib/docker/volumes，然后崩溃。修复就是这么简单

docker system prune --volumes -f && rm /var/lib/docker/volumes/metadata.db && docker-compose up -d
