IO timeout on N8000 NFS client

Publication Date:  2012-09-18 Views:  45 Downloads:  0
Issue Description
1. NFS client output information: Feb 9 09:21:42 mdud-ms01 kernel: nfs: server 192.168.0.51 not responding, still trying
Alarm Information
None
Handling Process
Modify client loading parameters:
mount -t nfs -o rw,intr,tcp,bg,timeo=600
Main reasons:
1. timeo=60 means 6 seconds, the original parameter is 10, making warning of no responding reported if IO request is not dispending in one second.
2. tcp  UDP is default parameter, but TCP is more stable which can help accelerate response.
3. intr allow client operation interrupted, in case console breakdown when the operation on mount point.
4. bg enable uncompleted operations running in background, not to block following operations.   

Root Cause
This information emerges when client IO read-write operation timeout. This timeout value can be modified through timeo.
Suggestions
Recommend optimum mount parameters to customers before NFS method mounted.
