![systemd 关闭:90 秒延迟,journalctl 显示停止 /dev 和 session-5.scope 超时](https://linux22.com/image/106491/systemd%20%E5%85%B3%E9%97%AD%EF%BC%9A90%20%E7%A7%92%E5%BB%B6%E8%BF%9F%EF%BC%8Cjournalctl%20%E6%98%BE%E7%A4%BA%E5%81%9C%E6%AD%A2%20%2Fdev%20%E5%92%8C%20session-5.scope%20%E8%B6%85%E6%97%B6.png)
我的 Kubuntu 16.04 关闭速度异常缓慢,并且journalctl -b-1
在一些超时错误周围显示 90 秒的延迟。如何找到这些关闭问题的原因并(希望)解决问题?
时间线:
- 关机开始:13:00:38
- 出现错误之前的最后一次活动:13:00:40
- 错误期间:13:00:50-13:02:08(见下面的日志)
- 关机完成:13:02:09

根据您发布的日志,关闭过程中的挂起之一与停止加密交换磁盘有关。
您使用的是加密交换磁盘吗?您最近是否测试过安装、使用和卸载/停止它?
