Integrating Shared Storage on a server (Ubuntu/Debian)

For Cloud Servers and Dedicated Servers managed in the Cloud Panel

This article explains how to mount shared storage on a server running Ubuntu/Debian.

Prerequisites

  • You assigned an IP address or domain to your server.

  • You have assigned the Shared Storage to your server

  • You set the access permissions for the desired server in the Shared Storage Details section.

  • You have downloaded the Kerberos key.

  • You have taken note of the NFS path.

Please Note

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

  • Make sure that the krb5 and nfs packages are installed. To install these packages, enter the following command:

    Ubuntu 16.04 and Debian 10

    apt-get install nfs-common krb5-user


    Ubuntu 18.04, Ubuntu 20.04, Ubuntu 22.04 and Debian 11
    To install krb5, enter the following command:

    apt-get install krb5-user


    To install nfs, enter the following commands:

    sudo apt update
    sudo apt install nfs-common

  • Open the /etc/default/nfs-common file using the vi editor. To do this, enter the following command:

    [root@localhost ~]# vi /etc/default/nfs-common

Additional Information about the vi editor

  • Press the [i] key. In this mode, the entered characters are immediately inserted into the text. To enter the command mode, press [ESC] afterwards. When you use command mode, your keyboard input is interpreted as a command.

  • To exit vi and save the file, type the command :wq, and then press Enter.

  • To enable the NEED_GSSD parameter, enter yes in the NEED_GSSD line in /etc/default/nfs-common.

  • Open the zipped Kerberos key file.

  • Copy the krb5.conf and krb5.keytab files.

  • Paste the files into the /etc folder.

Note

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

  • To start the required services manually, enter the following commands:

    Debian 10 and 11:

    systemctl start rpc-gssd

    Ubuntu 16.04:

    systemctl start gssd

    Ubuntu 18.04, Ubuntu 20.04 and Ubuntu 22.04:

    systemctl start rpc-gssd

  • Create the directory under which the storage is to be mounted.

    mkdir /mnt/nfs

Note

To mount multiple shared storages, create another directory, (e.g. /mnt/nfs2 etc.) Then perform the next step for all shared storages.

  • To mount the shared storage permanently, open /etc/fstab with the editor (for example, vi) and insert the desired mount point in the following format:

    vid12345.nas1.lan:/vid12345 /mnt/nfs nfs sec=krb5 0 0

    Example:

    vid15943.nas3.lan:/vid15943 /mnt/nfs nfs sec=krb5 0 0

Note

You need the NFS path for this.

  • To have the new entry in /etc/fstab checked and the shared storage mounted, enter the following command:

    mount -a

The shared storage is mounted.
