Issue

  • Multiple NFS clients have been sending the message nfs: server Data_LIF_IP not responding, still trying in the middle of every night. 
  • From the PerfArchive log, all we can see is that NFS I/O suddenly stopped, and there are no signs of high latency behaviors.
  • From the packet trace log:
  1. The storage system failed to receive any further NFS requests during the period when these client messages were being sent
  2. The client was repeatedly sending TCP Retransmission packets to the storage system
