Home Server & Cloud Infrastructure Cloud Server Integrating a Shared Storage on a Server

Integrate shared storage on a server (AlmaLinux 8 and Rocky Linux 8)

For Cloud Servers and dedicated servers that are managed in the Cloud Panel

To integrate shared storage on a server with AlmaLinux 8 or Rocky Linux 8 installed:

Requirements
  • You have assigned an IP address or a domain to your server.
  • You have set the access authorizations for the desired server in the detailed view of the shared storage.
  • You have downloaded the Kerberos key.
  • You have noted the NFS path.
  • You have logged in to the server as an administrator.
Note

If you have assigned a domain to the 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:

    [root@localhost ~]# yum install nfs-utils krb5-workstation

  • To start the installation, press the y key.
  • Open the zipped Kerberos key file.
  • Copy the files krb5.conf and krb5.keytab.
  • Paste the files into the /etc folder.
Note

If you are using a local computer with a Windows operating system, you can transfer the files easily and conveniently using the WinSCP application. WinSCP is a graphical open source SFTP and FTP client for Windows. You can download the application from the following website:

https://winscp.net/eng/download.php

  • Optional: If the error message Failed to issue method call:No such file or directory is displayed, execute the following commands:

    [root@localhost ~]# ln -s /usr/lib/systemd/system/nfs-secure.service /etc/systemd/system/multi-user.target.wants/

    [root@localhost ~]# ln -s /usr/lib/systemd/system/nfs.service /etc/systemd/system/multi-user.target.wants/

  • To restart the server, enter the following command:

    [root@localhost ~]# reboot

  • Create the directory under which the shared storage is to be integrated.

    [root@localhost ~]# mkdir /mnt/nfs

  • Open the /etc/fstab file with the vi editor.

    [root@localhost ~]# vi /etc/fstab

  • To mount the shared storage permanently, add 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

Notes
  • The vi editor has an insert mode and a command mode. You can call up insert mode with the [i] key. In this mode, the characters entered are immediately inserted into the text. To call up command mode, press [ESC]. If you use command mode, your keyboard input is interpreted as a command.
  • To exit vi and save the file, enter the command :wq and then press Enter.

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

    [root@localhost ~]# mount -a

  • To restart systemd, enter the following command:

    [root@localhost ~]# systemctl daemon-reload

  • To call up the shared storage, enter the following command:

    [root@localhost ~]# cd /mnt/nfs
