itopen组织
1、提供OpenHarmony优雅实用的小工具
2、手把手适配riscv + qemu + linux的三方库移植
3、未来计划riscv + qemu + ohos的三方库移植 + 小程序开发
4、一切拥抱开源，拥抱国产化

一、小于2T磁盘挂载方式

1.1 安装磁盘到电脑后启动系统

1.2 查找未分区的磁盘

  • 打开终端输入sudo fdisk -l查找到没有分区的磁盘
  • 已经分区的磁盘会有对应的Device Start End Sectors Size Type信息，而未分区的磁盘没有对应的信息，通过查看当前/dev/nvme0n1是新增加的未分区磁盘
$ sudo fdisk -l

1.3 磁盘分区

  • 对未分区的磁盘执行命令sudo fdisk /dev/xxx
  • 根据提示输入m查看指令信息
  • 根据提示输入n开始创建分区
  • 根据提示输入p表示创建主分区，或者输入区e表示创建逻辑分区：一块硬盘最多只能创建4个主分区，逻辑分区可以创建若干个
  • 根据提示输入x表示创建x个分区说明： 我们挂载磁盘一般只创建一个分区即可，直接输入1即可
  • 根据提示直接回车设置分区开始位置是从第2048个扇区开始： 由于EFI的兴起，要给EFI代码留磁盘最开始的1M空间，即2048521/(10241024)=1M，因此分区默认第2048个扇区开始
  • 根据提示直接回车设置分区结束位置为磁盘末尾
  • 根据提示输入w保存分区设置
$ sudo fdisk /dev/nvme0n1Welcome to fdisk (util-linux 2.34).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.Device does not contain a recognized partition table.

1.4 格式化分区

  • 输入命令sudo mkfs -t ext4 /dev/xxx进行格式化磁盘
  • 记住生成磁盘的UUID为挂载磁盘使用
$ sudo mkfs -t ext4 /dev/nvme0n1
mke2fs 1.45.5 (07-Jan-2020)
Found a dos partition table in /dev/nvme0n1

1.5 设置开机自动挂载

  • 打开文件/etc/fstab添加新分区挂载到/data目录
$ sudo vim /etc/fstab
# /datb was on /dev/nvme3n1p1 during installation
UUID=330fdef4-df72-47ab-afa0-0ff08ae4999f /data           ext4    defaults        0       2

1.6 重启系统

  • 系统重启后查看已经有目录/data表示挂载新磁盘成功

    1.7 删除分区

  • 卸载分区：使用sudo umount xxx

  • 对已分区的磁盘执行命令sudo fdisk /dev/xxx

  • 根据提示输入m查看指令信息

  • 根据提示输入d开始删除最后一个分区，如果想删除更多的分区，则不停的输入d即可

  • 根据提示输入p表示打印分区表

  • 根据提示输入w表示保存分区设置

  • 删除/etc/fstab中原UUID挂载的磁盘
