      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?

            The issue is still there
            Test on trunk version: 4702 with Optiplex 9020 Raid 0.

                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?

                              @mutant Not sure but I think that FOG only see the disk not the volume.

                                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

                                        Well, seams like it all depends. I cannot give you an easy solution like “just do it this way and you’ll be ok” as I don’t have a similar machine here to test.

                                        What do you see when running the following command in debug mode: gdisk -l

                                        Maybe those links are helpful: http://serverfault.com/questions/226053/intel-matrix-storage-raid-and-linux-mdadm and https://forums.gentoo.org/viewtopic-t-888520-start-0.html

                                        Also check out the device files you have in /dev/md/ and let us know.

                                        Edit: fakeraid is even more complicted than I had in mind: https://raid.wiki.kernel.org/index.php/RAID_superblock_formats
                                        See if you can find out how your RAID was setup in the first place. Then we might be able to find a solution to image this thing too.

                                          Just posting some of my own success with RAID and fog.

                                          I have a genuine hardware RAID setup at the house, I just got done installing CentOS 7 on it.

                                          It’s setup with two sata hard drives in RAID 1 configuration.

                                          I was having a very hard time trying to access the logical RAID 1 volume, and the below kernel options weren’t working, and I wasn’t having luck with finding what the system was refering to it as either.

                                          However - I think I might have come across a better solution.

                                          fdisk -l clearly shows two disks with exact size, model, and partitions.

                                          I simply created a new a new image using multiple partition image - single disk (not resizeable)

                                          and obviously I assigned that to the host, and for “host primary disk” I just entered /dev/sda and it worked like a charm.

                                          I’m a little curious about how my RAID 1 controller card would react if FOG tried to resize /dev/sda alone…

                                          Perhaps the RAID card will make those changes to sdb ? maybe the RAID 1 volume will degrade! lol

                                          I have no idea… but…

                                          this is a really good way to get an image off of a RAID 1 system and then put it onto a NON-RAID system. 🙂

                                          I’ll experiment with this and the resizable images.

                                            When setting the “Host Primary Disk” to /dev/md126 because there is no /dev/md0.

                                            It looks some kind of fog bugs when processing fakeraid Raid0 partition.

                                            It has problem to properly read the raid0 partition and it tries to read d1pp1.im* file instead of d1p1.im* file.
