Benjamin Cane has nearly 10 years of experience in Linux systems administration. His first systems administration role was in 2006. At that time, he worked for a web hosting company supporting thousands of FreeBSD and Linux systems. Afterwards, he joined a managed services company that specialized in managing mission-critical systems. There, he worked his way to the position of a lead systems engineer, providing 24x7 support for highly critical enterprise systems that ran Red Hat Enterprise Linux. Now, Benjamin is a systems architect. He focuses on building High and Continuous Availability environments within the financial services industry. He is also currently a Red Hat Certified Engineer and Certified Ethical Hacker. With his experience in mission-critical environments, he has learned to identify and troubleshoot very complex issues quickly, because often these environments have a low tolerance for downtime. Being able to identify the root causes of very complex systems issues quickly is a skill that requires extensive knowledge of Linux and troubleshooting best practices. In addition to this book, Benjamin writes about Linux systems administration and DevOps topics on his blog at http://bencane.com. He is also the project founder for Runbook (https://github.com/Runbook/runbook), an open source application designed to monitor and automatically resolve infrastructure and application issues.

NFS – Network Filesystem

Looking at the /data filesystem we can see that the filesystem type is set to nfs4. This filesystem type means that the filesystem is a Network Filesystem (NFS).

NFS is a service that allows a server to share an exported directory with other remote servers. The nfs4 filesystem type is a special filesystem that allows the remote servers to access this service as if it was a standard filesystem.

The 4 in the filesystem type denotes the version to use, which means the remote server is to use Version 4 of the NFS protocol.

Tip

Currently, the most popular versions for NFS are versions 3 and 4, with 4 being the default for Red Hat Enterprise Linux 6 and 7. There are quite a few differences between version 3 and version 4; however, none of those differences are enough to make a difference in our troubleshooting methodology. If you find yourself running into issues with NFS Version 3, then you can most likely follow the same types of steps that we will follow in this chapter...
