nfs: server xxx.xxx.xxx.xxx not responding, still trying
Applies to
- ONTAP 9
- NFSv3
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:
- The storage system failed to receive any further NFS requests during the period when these client messages were being sent
- The client was repeatedly sending TCP Retransmission packets to the storage system
