Failed to read back partitions

Jedi · Apr 24, 2019, 11:15 PM

I have an OS installed on a hardware RAID controller with two 2TB SSD’s.

I have taken an image. It had to be “Multiple Partition Image - Single Disk (Not Resizeable)”. The “Single Disk - Resizable” option would not work for some reason.

Now I am wanting to deploy the image to a different drive on the same computer (a 2TB HDD).

I unplugged the sata cables for all the drives except the one I am wanting to deploy the image to.

When I attempted to deploy the image I got the following error:

Failed to read back partitions (runPartprobe)
Args Passed: /dev/sdd

Any help with this would be much appreciated.

Let me see if I understand this correctly. We are talking about the target computer right?

That target computer has a hardware raid controller in it, but its presenting the drive as sdd?

I unplugged the sata cables for all the drives except the one I am wanting to deploy the image to.

Would that make /dev/sdd become /dev/sda?

What I want you to do is reinstall all of the drives into that target computer. Goto FOG Configuration->FOG Settings, then hit the expand all button. Somewhere in that list find “kernel args”. Place the following parameter in that field mdraid=true. Save the settings.
Then setup a new capture/deploy task (don’t care) but before you schedule the task, tick the debug check box then schedule the task.

PXE boot the target computer, after a few enter key presses you will be dropped to a FOS linux command prompt. At the FOS command prompt key in lsblk and fdisk -l and post the results here. This will show us the exact geometry of the disks.

Hi George,

Thank you for your reply. My system is Ubuntu 19.04 so I just took the output from terminal, hope that’s ok?

The image was taken from /dev/sdd and I am wanting to deploy it to /dev/sdb

In case its relevant I specified “/dev/sdd” as Host Primary Disk to prevent FOG taking Windows as the image.
