systemd - 启动进入紧急模式并出现错误 - /home 依赖失败

systemd - 启动进入紧急模式并出现错误 - /home 依赖失败

最近,我更新了我的 Arch Linux 安装。我尝试每两周这样做一次。完成后,我重新启动并收到一条错误,表明 /home(我的主分区)的依赖项失败。启动过程立即进入紧急模式。我发现我的主分区根本没有被安装。奇怪的是,我可以进入紧急模式,然后退出。之后,主分区就会安装并且系统加载得很好。

我应该提到我的主分区是BTFS而我的根分区是分机4。我的文件中有一个 HOOK /etc/mkinitcpio.conf,可以在启动时扫描 btrfs。它正在工作,我可以看到它输出正在扫描 btrfs。

它确实告诉我检查输出,journalctl -xb但是,不明白为什么我的主分区没有安装。

我读过类似的帖子,说要检查我的文件中主分区的 UUID /etc/fstab。我的 fstab 文件中的所有内容看起来都不错,但我决定放入 arch 安装 USB 并重新生成文件。这并没有解决问题。

这是我的 Journalctl -xb 输出的一部分:

这是我的/etc/fstab文件(出于安全原因,我故意删除了其他 UUID):

我想永久的解决方案是复制 BTRFS 分区中的所有内容,将其重新格式化为 EXT4,然后将文件放回其上。我不一定想这样做,因为这会花费很多时间,但这可能就是需要做的。

任何帮助将不胜感激,我觉得我已经尝试了我所知道的一切。

如果您需要任何其他输出或日志,请告诉我。

答案1

-netdev选项添加到fstab“/home”条目。看来安装的依赖项是网络管理堆栈。
