NFS client hangs indefinitely following a network partition and recovery
Applies to
- ONTAP 9
- RHEL7.6 kernel (3.10.0-957*el7)
Issue
- After upgrading from the RHEL7.5 kernel (3.10.0-862*el7) to the RHEL7.6 kernel (3.10.0-957*el7), reads or writes to a NFS share by a NFS client hang indefinitely following a network partition and recovery.
- This is new behavior that is not seen in versions of RHEL 7 prior to RHEL 7.6.
- If migrating lif, can not encounter the same problem.
