Notes and workarounds
NFS client 4.1 is not supported
If you are using the RHEL 7.4 operating system, you must configure NFS 4.0 on delegate hosts. A file locking defect might exist in NFS 4.1 with RHEL/CentOS 7.4. For more information, refer to topic "Configuring NFS 4.0" in the Control Center installation guide or upgrade guide.
