RHEL 6 NFS client takes longer than a RHEL 5 NFS client to mount NFS exports

Solution Unverified - Updated -

Issue

  • In RHEL 5 if I do an ls it's very quick. In RHEL 6.2 it takes 30 seconds to list them.

  • RHEL 6 NFS client takes longer than a RHEL 5 NFS client to mount NetApp Filer exports. Tcpdump contains ICMP Destination unreachable (Port unreachable) after a UDP GETPORT Reply from the NetApp Filer.
