如果有帮助，我会使用btrfs进行故障排除

在manjaro论坛上讨论

有一个拙劣的PR（https://github.com/Nefelim4ag/systemd-swap/pull/140）修改了btrfs代码路径，可能的修复仍在进行中（https://github.com/Nefelim4ag/systemd -swap / pull / 144）。

由于＃144提交者已经有一段时间没有看到更新了，因此我可以修复并合并它。

糟糕，不是要立即关闭此功能。
c8431ddbd728e7da14eaa69362a2ef0becf6074d是否已为您修复了此问题？

@ Jarel1337当我回到家时，我会给您反馈。 我应该在这里使用arch repo还是git clone中的版本？

请使用master（此处为aur软件包或仅进行安装）

似乎对我不起作用，我尝试删除旧的systemd-swap文件夹并重新启动系统，但它对我来说总是出错。

我正在使用aur包btw

@ Jarel1337对我也一样（例如@nathanielcwm）通过make install

最新版本> journalctl -p err -b swap File failed to activate

@nathanielcwm您是否还在使用btrfs？

要解决此问题，直到合并了修订，您可以设置swapfc_force_use_loop=true

编辑：显然， systemd-swap.service单元不允许循环设备，解决方法是简单的一个衬套，并且在当前的主设备上。

应该通过使用dd而不是fallocate （我什至忘记了dd未用于某些文件系统，这应该早就发生了）

我希望它能解决该问题，解决方法： swapfc_force_use_loop=true向我显示systemctl status systemd-swap.service invalide参数

也可以与硬件相关吗？

您将需要手动向后移植两个提交才能使其正常工作，我建议暂时只使用master

最后从master进行安装，问题消失了。 非常感谢@ Jarel1337 ！
我将等到拱形Linux上游存储库中。
