Docker无法使用装载硬盘上的数据重新启动

我使用mount/dev/vdb/mnt/data在/mnt/data上挂载硬盘驱动器

更改：/etc/docker/daemon.json中的默认docker文件夹

一切正常

但在计算机重新启动后： docker守护程序无法重新启动

我得到了这些错误：

$ service docker start
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

Docker在非OS磁盘mnt/data/Docker装入之前启动。您可以要求docker在启动docker之前等待成功装载

找到装载，编辑Docker systemd服务文件以满足要求，并等待装载后再开始

systemctl list units-type==挂载列出所有挂载。 systemctl状态获取有关装载的详细信息。查找与您的装载目录匹配的目录 sudo nano/lib/systemd/system/docker.service编辑您的systemd服务文件 在After和Requires行的末尾添加名称

After=network-online.target firewalld.service containerd.service <example.mount>

您是否将新的挂载添加到/etc/fstab@Henry你说得对，我只是在启动时添加了挂载过程。问题解决了。不知道为什么docker不想以其他方式重新启动。没有/etc/fstab条目，docker根本无法访问驱动器/数据，因此这是必须完成的一个强制性步骤
