我有一个 EC2 实例,它在每个工作日结束时停止,然后第二天早上通过 Control-M 作业重新启动。大多数实例启动时都没有问题,但是偶尔我们会看到错误,因为启动时实例可达性检查失败。
以下内容取自系统日志:
[ 8.688983] RPC: Registered named UNIX socket transport module.
[ 8.693873] RPC: Registered udp transport module.
[ 8.697700] RPC: Registered tcp transport module.
[ 8.702012] RPC: Registered tcp NFSv4.1 backchannel transport module.
[ 11.203839] ixgbevf: Unable to start - perhaps the PF Driver isn't up yet
[ 11.575869] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
[ 12.594246] ixgbevf: Unable to start - perhaps the PF Driver isn't up yet
[ 19.465602] Adding Red Hat flag eBPF/event.
我对这种故障排除不是很有经验,有人亲眼见过这个问题吗,或者能够提供有关为什么会发生这种情况的信息?
提前致谢。
答案1
实例状态检查失败表明实例的可达性存在问题。此问题是由于操作系统级错误引起的,例如:无法启动操作系统。无法正确安装卷。
