问题描述

节点意外重新启动。
或者节点在意外关闭后不会重新启动。
受影响节点上的服务处理器日志显示以下内容：

Record 454: Mon Feb 08 11:49:20.924775 2021 [IPMI Event.critical]: L2 watchdog timeout hard reset Record 455: Mon Feb 08 11:49:20.984259 2021 [Trap Event.critical]: hwassist l2_watchdog_reset (29) Record 456: Mon Feb 08 11:49:23.000822 2021 [SP.critical]: Filer Reboot

如果节点重新启动，可以在 EMS 日志文件中看到以下错误：

[cluster-01:mgr.boot.reason_abnormal:EMERGENCY]: System rebooted due to a watchdog reset.

如果节点无法重新启动，system sensors SP 可能会显示传感器不可用（na）或故障（Fault）：
