Solaris NFS Client increased CPU Usage With NFS4 & NetApp OnTap 7.3.7P2
Last updated on JULY 11, 2017
Applies to:Solaris Operating System - Version 10 3/05 and later
Information in this document applies to any platform.
Solaris 10 server that mounts an NFSv4 volume from a NetApp filer running Data OnTap v 7.3.7P2
experiences a drop in performance defined as:
- a CPU with high system time - this might always be the same CPU, but there will be evidence of a "hot" thread or two. Systems with few CPUs will of course have more obvious high sys time than those with many CPU strands.
-responses/jobs are very sluggish on the NFSv4 mount.
-uptime shows higher than normal load. Again, this is relative to the number of available CPU strands.
The NetApp was recently upgraded to the 7.3.7P2 version of Data OnTap.
