Clonezilla Server Edition Installation on Ubuntu

clonezilla-logo

The tutorial describes installation steps for Clonezilla Server Edition (SE) on Ubuntu 16.04.1 LTS using a Bash script. Clonezilla is OpenSource Cloning System (OCS) and it is a partition and disk imaging/cloning program . It helps you to do system deployment, bare metal backup and recovery. Two types of Clonezilla are available, Clonezilla live and Clonezilla SE (server edition).

Clonezilla live is suitable for single machine backup and restore. Clonezilla SE is for massive deployment because it can clone many computers simultaneously. Clonezilla saves and restores only used blocks in the hard disk. It decreases time and saves the hard disk space and increases the clone efficiency.

Clonezilla is a part of DRBL (Diskless Remote Boot in Linux) which provides a diskless environment for client machines. Therefore we need to install and configure DRBL server first. I created DRBL deployment script deploy_drbl.sh that helps you to install DRBL and configure server on Ubuntu with a single Ethernet card. You have to provide only the name of Ethernet interface and the script creates virtual interface for you based on your physical interface. It also downloads a DRBL project public key, download and install drbl package from repository. The script starts interactive Bash and Perl scripts that come with drbl package.  It starts them in this order:

  • drblsrv  - prepares files for PXE client and generates PXE menu
  • drblpush - configures DNS, clients' hostname, Ethernet card, collects MAC addresses of clients, configures and starts DHCP server, diskless services and Clonezilla mode, PXE password, grephical/text boot menu, NAT services for clients and firewall rules
  • dcs - DRBL utility to switch the mode for clients

Here is a version of packages installed with DRBL.

Deploying DRBL Server

1. Starting Script
The script deploy_drbl.sh must be started with root privileges. Once you login to root account with sudo su command, assign execute privileges to the script.

$ sudo su
# chmod +x ./deploy_drbl.sh
# ./deploy_drbl.sh

Now enter the name of Ethernet interface which is connected to the Internet, e.g. eth0. The script creates a new virtual interface adding suffix 100 to the name of your Ethernet interface e.g. eth0:100. It also configures IP address 192.168.112.200/24 on your virtual interface. If you want to configure different suffix or IP address/mask on the virtual interface, just change a value of variables ipaddress, mask and suffix in the script. The script installs a package drbl from repository drbl testing.

Note: The script deploy_drbl.sh requires a working connection to the Internet in order to install DRBL server. The script sets only an IP address and a mask on the virtual  interface. It is your job to configure a correct IP address/mask on the physical interface. You also need to configure default route and add DNS server.  Here are my network settings /etc/network/interfaces.

2. DRBL Server Installation
The scripts deploy_drbl.sh automatically starts a script drblsrv with a parameter -i . The script drbl is responsible for installation of DRBL server.  Installation is interactive so you must provide answers for questions - either y or n. If the letter is capital, it is a default choice and you can press Enter or type particular letter to select this choice.

Picture 10 - Same IP address for Clients

Press Enter to reject the offer to configure the same IP addresses for clients.

3.7 DHCP Server

3.8 Diskless Linux Services

Select an option -p poweroff. Clients automatically power off once cloning is finished. When dcs script finishes, you can see the following command in your terminal window.

drbl-ocs -b -l en_US.UTF-8 -y1 -p poweroff select_in_client

-b - run program in batch mode, i.e without any prompt
-l - language en-US.UTF-8
-y1 - clonezilla server as restore server
-p - shutdown client when cloning/restoring finishes
select_in_client - client chooses either to clone or restore

You can put the command inside the script /etc/init/clone.conf to start Clonezilla automatically after boot. To clone clients using multicast in order to speed up cloning process, use the following command.

drbl-ocs -b -g auto -e1 auto -e2 -x -r -j2 -sc0 -p poweroff --time-to-wait 30 -l en_US.UTF-8 startdisk multicast_restore core_linux sda

All options are explained here.

5. Troubleshooting

Here are the problems I noticed during writing the tutorial.

5.1 Client Does Not Get IP Address

Check if DHCP service is running with the command:

$ ps -ef | grep dhcpd | grep -v grep

picture25_dhcp_service_running

Picture 25 - Checking DHCP Service

If you cannot see the output above, DHCP service is not running. Check the service status with the command:

$ systemctl status isc-dhcp-server

picture26_dhcp_service_not_active

Picture 26 - DHCP Service Disabled and Not Active

We can see that DHCP service is disabled and not active. We can enable it with the command:

$ systemctl enable isc-dhcp-server

picture27_dhcp_service_enabled_but_not_active

Picture 27 - DHCP Service Enabled But Not Active

DHCP service is enabled but not active. Activate the service with the command:

$ systemctl start isc-dhcp-server

picture28_dhcp_service_enabled_and_active

Picture 28 - DHCP Service Enabled and Active

You can check DHCP messages in /var/log/syslog file.

picture29_obtaining_ip_from_dhcp

Picture 29 - Obtaining IP Address for Client

Obtaining IP address 192.168.112.1 for client with a MAC address 09:00:27:93:43:bb via the interface enp0s3.

End.

  1. can't get the script to run. I get bash: ./deploy_drbl.sh: /bin/bash^M: bad interpreter: no such file or directory. what's up???

    • please disregard my last comment. i used wget to download the file and that solved my previous issue. However, now I get DRBL Project public key '1024D/D7E8DF3A' was not properly installed, exiting. here is a picture of the error - http://i.imgur.com/dLRTEzB.jpg

  2. I got an error that the public key wasn't found, so I had to run apt-key list and record the actual value of the key, and put that in the script file. Just a note in case anyone else runs into this.
