Integrating Shared Storage on a CentOS 7 Server

In this article, we'll show you how to add shared storage to your server running CentOS 7.

Prerequisites

You have assigned an IP address or a domain to your server.
You have set the access authorisations for the required shared storage in the detail view.
You have downloaded the Kerberos key.
You have made a note of the NFS path.

Please Note

If you assigned a domain to your server, it must be accessible on the Internet.

Make sure the krb5 and nfs packages are installed. To install these packages, type the following command:
yum install nfs-utils krb5-workstation
Open the zipped Kerberos key file.
Copy the files krb5.conf and krb5.keytab.
Add the files to the /etc folder.

Please Note

If you use a local Windows computer, you can transfer the files easily with the WinSCP program. WinSCP is a graphical, open-source SFTP and FTP client for Windows. To download the program, click here.

Activate and start the required services. To do this, enter the following commands:
systemctl enable nfs-secure
systemctl start nfs-secure
Optional: If the error Failed to issue method call:No such file or directory is displayed, execute the following commands:
ln -s /usr/lib/systemd/system/nfs-secure.service /etc/systemd/system/multi-user.target.wants/
ln -s /usr/lib/systemd/system/nfs.service /etc/systemd/system/multi-user.target.wants/
To restart the server, type the following command:
reboot
Create the directory where the storage should be mounted.
mkdir /mnt/nfs
To permanently mount the shared storage, open /etc/fstab with a text editor (such as vi) and add the desired mount point in the following format:
vid12345.nas1.lan:/vid12345 /mnt/nfs nfs sec=krb5 0 0

Please Note

To do this, you will need the NFS path.

To check the new entry in /etc/fstab and mount the shared storage, enter the following command:
mount -a

The shared storage is now mounted and available to use in your server.
