    Sorry Wolf…didn’t see yours. Yes, i was using MPI - non-resizeable for the image type as to try and not break the array while imaging.

      Rebuilding inits with dmraid and mdadm tools, as well as currently compiling 3.18.0 kernels with support for RAID devices.

      When it’s pushed, do you mind trying it out, and see if anything better happens?

        2759 has the mdadm/dmraid tools in the init and raid tools built into the kernel.

        Hopefully this will suite your needs.

          Hi,

          this is an old thread but I have the same problem.

          I’m using Dell Precision Rack 7910 with RAID1.

          Is the INTEL RAID working now with FOG?

            @eddy According to Tom’s last posts, the support should be there… no way to really know but to try. Either way, you’ll need to move to the latest FOG Trunk version to find out. Here’s how you do that:

              It wouldn’t be optimal, but have you tried the dd method?

                    I don’t know if this will help anybody.

                    https://github.com/FOGProject/fogproject/pull/53

                    But I’m not going to try auto mounting raid myself.

                    Follow the instructions (essentially set the host’s kernelArgs to contain mdraid=true)

                      putting Host Kernel Arguments “mdraid=true” still result in the same issue that when deploy image it will break the raid and only image one disk.

                          Kernel was updated last week when upgrade using git to trunk version 4702.
                          The git source “S99fog” file does have the $mdraid change.

                            Again,

                            I need more information.

                            What is happening, what isn’t working? Does the system recognize the volumes at all?

                              I have Dell Optiplex 9020s at work. The factory firmware settings come with the hdd operating in “RAID ON” mode instead of AHCI. I’ve been able to successfully image this system with FOG Trunk. Have you played with these HDD operation mode settings? Does the 9020 have two physical hard drives, or just one? What is not working? Can the system network boot? Can you upload an image? Can you download an image? Can you provide a photograph of the issue you’re seeing?

                                    What does it look like on the original system?? If this is a real RAID controller you shouldn’t see the two disks in Windows! A real RAID is not configured in Windows/Linux but has it’s own (BIOS-like) configuration. You’d have to configure the RAID on the target system before cloning. This cannot be done by FOG!

                                      @Uncle-Frank Very true.

                                      When you’re using hardware RAID, the OS is oblivious to it. Even FOG would be oblivious to a good hardware RAID setup.

                                      Since it’s clearly not hardware RAID, or a good hardware RAID - use “Multiple Partition Image - All Disks”

                                        Re-reading your post and trying to find out a bit more about the RAID in Optiplex 9020 I noticed that I was totally wrong, sorry! This is not a real RAID but a fakeraid (as you already said in your first post 😉). It is Intel ICH8R (82801HR) southbridge which they call a ‘firmware RAID’. After setting it up properly on the target machine (http://www.dell.com/support/article/us/en/19/SLN153494/EN) you still need to address this in linux as well.

                                        Do you have ‘Host Primary Disk’ configured for those hosts? FOG is not intelligent enough yet to find out about (fake)RAID setup and use the correct device just by itself! You might be fine not setting ‘Host Primary Disk’ for the host you are getting the image from as /dev/sda should be equal to /dev/sdb (FOG uses /dev/sda as default). But you need to set this to /dev/md0 to make FOG properly deploy to your RAID.

                                        By the way: “Multiple Partition Image - All Disks” probably won’t help you as the RAID array won’t be in sync if it is not properly deployed through the correct device file AFAIK.

                                          Set the “Host Primary Disk” to /dev/md0 and test again and still no go.

                                          Went into debug mode to check the raid status

                                          mdadm -D /dev/md0
                                          shows the status of md0 is “inactive”

                                          cat /proc/mdstat
                                          shows only md126 is “active” and md127 is inactive

                                          The problem seems that FOG does not assemble /dev/md0 properly

                                          Re-run the task after setting the “Host Primary Disk” to /dev/md126
                                          still not go , it shows “Problem opening /dev/md126p1 for reading! Error is 2. The specified file does not exist!”

                                          The problem seems that FOG try to read from /dev/md126p1 instead of /dev/md126
