Burn a DVD on ClearOS from Command Line
This guide will step you through the process of using ClearOS to burn a DVD-R/DVD+R/DVD+RW/DVD-RW disk to an attached or installed DVD+RW/DVD-RW burner.
Requirements
Your burner must be compatible with ClearOS. Generally speaking, if your burner works with both Windows and Mac it likely will work with ClearOS as well.
Finding your device
The first step is to find your device. For my examples in this howto, I will be using a LG Ultra Slim Portable DVD Writer (SP60). Because it is USB, I can see it when I insert it into my server. I run this command before inserting it:
lsusb
Then I run the command again after inserting it:
lsusb
This shows my device as:
Bus 002 Device 008: ID 0e8d:1887 MediaTek Inc.
I can also see in my messages log that it sees my DVD burner:
Jun 25 16:34:37 kvm1 kernel: usb 2-1.2: new high speed USB device number 8 using ehci_hcd Jun 25 16:34:37 kvm1 kernel: usb 2-1.2: New USB device found, idVendor=0e8d, idProduct=1887 Jun 25 16:34:37 kvm1 kernel: usb 2-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Jun 25 16:34:37 kvm1 kernel: usb 2-1.2: Product: MT1887 Jun 25 16:34:37 kvm1 kernel: usb 2-1.2: Manufacturer: MediaTek Inc Jun 25 16:34:37 kvm1 kernel: usb 2-1.2: SerialNumber: KZ4E5F24221 Jun 25 16:34:37 kvm1 kernel: usb 2-1.2: configuration #1 chosen from 1 choice Jun 25 16:34:37 kvm1 kernel: scsi5 : SCSI emulation for USB Mass Storage devices Jun 25 16:34:38 kvm1 kernel: scsi 5:0:0:0: CD-ROM HL-DT-ST DVDRAM SP60NB50 1.00 PQ: 0 ANSI: 0 Jun 25 16:34:38 kvm1 kernel: scsi 5:0:0:0: Attached scsi generic sg3 type 5 Jun 25 16:34:38 kvm1 kernel: sr0: scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda tray Jun 25 16:34:38 kvm1 kernel: Uniform CD-ROM driver Revision: 3.20
Here I can see that ClearOS calls my device sr0 or /dev/sr0. If you aren’t using USB for your DVD burner the device will have shown up in your ‘dmesg’ log the last time your server booted. You will have a similar message to what is listed above.
Getting the tools
You will need a package installed called dvd+rw-tools.
yum --enablerepo=clearos-core install dvd+rw-tools
Prepping the image
Before committing the image to the disk you will need to make your .iso file. If you already have an .iso file ready, skip this section. If you wanted to create a backup of your flexshare called ‘accounting’ you would do the following:
mkisofs -r -o /root/accounting-backup.iso /var/flexshare/shares/accounting
Burning the image
You will need to know the name of the device which we identified earlier. In my case, it is /dev/sr0. Next commit your ISO image to the disk with the following:
growisofs -Z /dev/sr0=/root/accounting-backup.iso
You can also use this method to make a ClearOS installation DVD. For example:
growisofs -Z /dev/sr0=./clearos-professional-6.5-x86_64.iso
You should get output similar to this:
