将WSL2从C盘迁移到D盘

 
  • Aug 20, 2023

众所周知，C盘是操作系统所在的分区，如果其被过多软件占用，将会导致系统的响应速度变慢，影响整体性能。随着WSL2的逐渐使用，其虚拟硬盘渐变大，因此考虑将其迁移到D盘

迁移

  • 使用命令wsl --export <distro name> d:\<tar name>.tar备份发行版
  • 使用命令wsl --unregister <distro name>卸载当前发行版
  • 使用命令wsl --import <distro name> d:\<dir name> <tar path> --version 2导入此前备份的发行版
    • 若这一步出现错误，见下一节

wsl –import出现“未指定的错误”

  • 使用命令choco install lxrunoffline安装LxRunOffline
  • 进入目录C:\tools\lxrunoffline，运行命令.\LxRunOffline.exe install -n <distro name> -d <dir path> -f <tar path>，等待安装完毕即可
    • 若这一步出现错误，见下一点
  • 假如上一步报错：[ERROR]Couldn't get the value "DistributionName" of the registry key "Software\Microsoft\Windows\CurrentVersion\Lxss\TryStoreWSL". Reason: 系统找不到指定的文件，按下win+R，输入regedit进入注册表编辑器，在\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Lxss路径下找到TryStoreWSL并删除它，再重复上一步即可

设置用户名

  • 重新安装发行版后，将会以root用户登录，使用命令sudo -i -u <username>即可登陆回原来的用户
  • 将原有的用户设置为默认用户会更方便，编辑或新增/etc/wsl.conf文件，添加如下行后重启wsl即可： 
    [user]
default=<username>

    升级到WSL2

  • 按以上步骤导入后，WSL版本可能为1，执行命令wsl --set-version <distro name> 2可升级为wsl2
  • 我遇到了报错： 
    导入分发失败。

    出现错误的原因不明，但解决方法就是把以上涉及的文件全部删掉，成功升级到WSL2，之后再重新安装所需的程序。
