How to mount a WD Book Live as NFS in OEL6U3

Scenario : I have a Windows 8 (Host) laptop on which I am running two OEL6U3 (Guest) machines in a Virtual Box. I want to have a shared mount between the two Linux machine which will allow me to read/write from both the machines concurrently. Its a very common scenario for a High Availability Environment. Virtual Box provides a facility of creating sharable VDI disks which can be mounted on multiple machines, but it doesn’t allow concurrent read/write access from multiple machines. If you are installing RAC database then its still achievable, because ASM will provide the feature of concurrent read/writes, but if you want to install a WebLogic cluster with High Availability the recommended approach would be to have a Shared Mount. Step to create a shared nfs mount is fairly simple. I am using a WD My Book Live, and will mount the Public folder as shared mount 1. Get the hostname/ip of the WD device. 2. On the Linux Machine 1 create the folder where you want to mount the nfs ...
