基于 Debian Jessie 运行 RasPBX - 我尝试更改一些 .conf 文件，但它们总是在重新启动后恢复。我最初以为这是 dhcp 搞乱了事情，但事实证明重启后什么都没有幸存。甚至我在主目录中创建的 .txt 文件也会被删除。
tl;dr - SSH 输入，更改内容，重新启动，恢复所有更改。

拒绝运行 fsck：
fsck from util-linux 2.25.2
e2fsck 1.42.12 (29-Aug-2014)
/dev/mmcblk0p2 is mounted.
e2fsck: Cannot continue, aborting.
另外，拒绝卸载 /dev/mmcblk0p2 - 声称目标正忙。
尝试过：
shutdown -F -r now
导致：
Code should not be reached 'Unhandled option' at ../src/systemctl systemctl.c:6316, function shutdown_parse_argv(). Aborting.

答案1
我也有同样的情况（重新启动没有停留 - 重新启动时，总是进行 fsck）。对我来说，原因是 SD 卡快要死了。您是否可以尝试将此卡的内容添加到另一张卡上？
