在我们的常规维护期间，重新启动一个SRX345后，发现它卡在db模式（调试模式）下。
经过简短，快速的分析，我发现Juniper JunOS设备可能会卡在引导过程中或无法引导OS，在极少数情况下，是在突然断电或不正常的电源关闭之后。杜松 路由器，交换机和防火墙 可能会遇到文件系统损坏的情况，这会阻止设备恢复到功能状态。建议客户最小化其日志中国体育彩票开奖，以防止对文件系统进行过多的读/写操作，这减少了对存储介质的压力并减少了可能出现此问题的可能性。此外，如果突然的电源故障在很短的时间内发生瞬变，则UPS的可用性也可以防止设备突然断电。
在这些情况下，您不必担心会损坏硬件，因为硬件无法区分正常关机和拉电源线之间的区别。潜在的损坏与文件系统结构有关。如果在操作系统运行期间中断计算机的电源，则数据可能会损坏。数据可能在节点中，这可能导致文件丢失或文件内容损坏。
尽管很少见，但在使用基于UNIX / BSD的操作系统（例如Junos）访问基于闪存的存储介质的平台上，更可能发生此问题。
“尽管极少数，突然断电可能会损坏文件系统，这可能在下次启动时引起问题。使用request system halt或request system reboot命令来正常关闭或重新引导操作系统。一旦操作系统停止，就可以安全地断电。” – from O’Reilly Media的《 JUNOS企业转换》一书。
有几个知识库讨论此修复程序。 KB29811 正在使用USB将快照从运行状况良好的设备复制到故障设备。 KB20046 建议按空格键转到u-boot提示符，然后输入一些命令以解决问题。
