存储接口 (LIF) 丢弃 ICMP 数据包导致延迟
适用场景
- ONTAP 9
- SMB
- NFS
问题描述
- 主机尝试 ping cifsserver，但没有收到响应，则报告如下错误：
05/12/2023 11:54:56:251 | 03 | 040 | p5136 | t1096 | GetVolumeStatus | DiskMonitorThread.cpp(117) | Successful attempt to ping the location: \\cifsserver.LOCAL\file0105/12/2023 11:54:56:380 | 03 | 015 | p5136 | t1096 | TestWriteAccess | DiskMonitorThread.cpp(32) | Fail test write access: A device attached to the system is not functioning.- 洪水
ping使用-f在 Linux 中，iscsi lif 报告数据包丢失，结果 icmp.ping.throttle当系统在一秒的时间间隔内收到大量 ICMP ping 数据包时，就会发生这种情况。- EMS 日志中显示以下事件：
Wed Nov 29 12:54:43 +0530 [NODE-01: kernel: icmp.ping.throttle:notice]: icmp_input: The system dropped 2180 ping packets after limiting the packets to 200 per second.Wed Nov 29 13:04:44 +0530 [NODE-01: kernel: icmp.ping.throttle:notice]: icmp_input: The system dropped 4522 ping packets after limiting the packets to 200 per second.Wed Nov 29 13:14:46 +0530 [NODE-01: kernel: icmp.ping.throttle:notice]: icmp_input: The system dropped 2013 ping packets after limiting the packets to 200 per second.Wed Nov 29 13:24:47 +0530 [NODE-01: kernel: icmp.ping.throttle:notice]: icmp_input: The system dropped 3477 ping packets after limiting the packets to 200 per second.
