Netapp filer ontap upgrade results in RHEL NFS clients receiving delayed RPC replies

Solution In Progress - Updated -

Issue

  • We have a netapp filer (nfs) issue on some oracle 12g RAC hosts, there are seven hosts, clustered in 2, 2, 3 formation. They were stable until this month of August 2015, the only difference I have seen is a change in the NetApp ONTAP version, on July 28th it was upgraded from 8.2.1 to 8.3 P2.

Environment

  • Red Hat Enterprise Linux 6.6 (NFS client)
  • kernel 2.6.32-358.0.1.el6.x86_64
  • kernel 2.6.32-504.30.3.el6.x86_64
  • NFSv3
  • Netapp filer ontap 8.3 P2
