N430x盒子和一体机默认都安装了OpenEuler 24.03 LTS，默认安装并使能了Docker。不过由于不同的N430x设置硬盘配置不太一样，有的安装了nvme固态硬盘，有的安装了sata固态硬盘、有的安装了机械硬盘，有的只有eMMC，所以为了达到最佳性能，需要将Docker目录设置到硬盘或者eMMC的特定分区上。
硬盘分区与格式化会丢失所有硬盘数据，请提前备份好数据！！！
sudo fdisk -l
从结果中查找/dev/sda /dev/sdb /dev/nvme /dev/nvme0n1等关键信息，如果有其中的任何一个，说明有磁盘，不过U盘等也是/dev/sda /dev/sdb这种名字，确认是如果插了U盘，需要将U盘排除掉。
输出例子：
[root@openEuler ~]# fdisk -l

如果有硬盘则进行接下来的步骤，如果没有硬盘，则无需进行接下来的步骤，直接跳到第二章。
如果对硬盘有特殊分区需求，则可以对硬盘进行分区操作，一般新买的硬盘或则设备自带的硬盘已经做了分区操作，此处只针对有特殊要求的使用者。
硬盘分区操作步骤如下(以nvme为例)：
[root@openEuler ~]# gdisk /dev/nvme0n1 #也可能是 /dev/sdb 或者 /dev/nvme0n1，具体看1.1的结果
GPT fdisk (gdisk) version 1.0.9
Partition table scan:
MBR: not present
BSD: not present
APM: not present
GPT: not present
Creating new GPT entries in memory. # 创建一个新的GPT分区表：
Warning! Unable to generate a proper UUID! Creating an improper one as a last
resort! Windows 7 may crash if you save this partition table!
Command (? for help):
输入n创建新的分区，如果只需要创建一个分区，后面几个就使用默认参数，直接回车即可：
Command (? for help): n
Partition number (1-128, default 1):
First sector (34-4000797326, default = 2048) or {+-}size{KMGTP}:
Last sector (2048-4000797326, default = 4000796671) or {+-}size{KMGTP}:
Warning! Unable to generate a proper UUID! Creating an improper one as a last
resort! Windows 7 may crash if you save this partition table!
Current type is 8300 (Linux filesystem)
Hex code or GUID (L to show codes, Enter = 8300):
Changed type of partition to 'Linux filesystem'
Command (? for help):
使用命令w保持分区信息，并使用y确认：
Command (? for help): w
Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!
Do you want to proceed? (Y/N): y
OK; writing new GUID partition table (GPT) to /dev/nvme0n1.
The operation has completed successfully.
至此硬盘分区就完成了。
硬盘分区后，需要在分区上创建文件系统，一般使用ext4文件系统，如果想使用别的文件系统类型也可以。
sudo mkfs.ext4 /dev/nvme0n1
[root@openEuler ~]# sudo mkfs.ext4 /dev/nvme0n1
mke2fs 1.47.0 (5-Feb-2023)
Found a gpt partition table in /dev/nvme0n1
Proceed anyway? (y,N) y # 此处需要输入y确认

创建挂载点（这里假设磁盘挂载到/bigdata/目录）：
sudo mkdir -p /bigdata
修改配置文件/etc/fstab,新增需要自动挂载的磁盘分区：
sudo vim /etc/fstab
以上面nvme的例子，新增如下行到配置文件末尾，保存并退出：
/dev/nvme0n1 /bigdata ext4 defaults 0 1
测试挂载：
sudo mount -a
使用lsblk命令验证是否挂载：
[root@openEuler ~]# lsblk

sudo systemctl stop docker
sudo systemctl stop docker.socket
sudo systemctl stop containerd
# 有硬盘的话在硬盘上创建目录
sudo mkdir -p /bigdata/docker
# 没有硬盘的话在eMMC上创建目录，mmcblk0p9默认挂载在/data/分区
sudo mkdir -p /data/docker
# sudo ln -s /data /bigdata
/etc/docker/daemon.json, 如果该配置文件不存在，则使用下面的命令创建配置文件sudo vim /etc/docker/daemon.json
将下面的内容增加到配置文件中并保存：
硬盘使用下面的配置：
{
"data-root": "/bigdata/docker"
}
没有硬盘使用下面的配置：
{
"data-root": "/data/docker"
}
sudo systemctl start docker
docker info -f '{{ .DockerRootDir}}'
[root@openEuler ~]# docker info -f '{{ .DockerRootDir}}'
/bigdata/docker #是我们前面配置的目录，说明已经生效
