Where is the .mbr file?



  • Is there a reason why when you capture an image there would not be the d1.mbr file in the image folder?

    I had written a lengthy post that seemed to have gotten deleted when i went to verify my email.

    I can provide more details if needed, but just wondered if there was something silly i am missing here. This is on a new install. One machine captured perfectly and then the last two images I tried to capture did not include the MBR file for whatever reason.

    Thanks!

    @Robotic said in Where is the .mbr file?:

    As you can see in the screenshot i added that one arg pertaining to nvme latency. That wouldnt affect the image capture process would it?

    No, shouldn’t cause this issue.

    What jumps at me in the file listing is this:

    /images/HP-9480:
    total 15882304
    drwxrwxrwx 2 root root 4096 Feb 6 10:11 .
    drwxrwxrwx 7 fogproject root 4096 Feb 6 09:36 …
    -rwxrwxrwx 1 root root 2 Feb 6 09:24 d1.fixed_size_partitions
    -rw-r–r-- 1 administrator administrator 1048576 Feb 3 08:58 d1.mbr
    ...
    

    Two things:

    1. The name in the listing is different than in the picture: HP-9480 vs. HP9480
    2. The file is owned by a user called administrator. Seems like someone messed with this image.

    No idea why d1.mbr is missing in /images/HP-9470 directory!?!



  • Sebastian, thanks for your reply!

    I am running dev-branch 1.5.7.109

    The reason I am doing that is because it was the only fix i could find for some of our newer machines with nvme drives. As you can see in the screenshot i added that one arg pertaining to nvme latency. That wouldnt affect the image capture process would it?

    One temporary fix i found was to fire up our older Fog server and copy the .mbr from the older images for the corresponding machine. That is why there is a difference in the screenshot and the output from the command I ran per your request later.

    @Robotic Can you please let us know the FOG version you are using? As well please run the following command and post output here: ls -alR /images

    Is there a reason why when you capture an image there would not be the d1.mbr file in the image folder?

    The only obvious reason I can think of right now is if you set the option Partition in the image settings to something like “Partition 2 only”.

    Do you get any error when deploying the image? I suppose so. Please take a picture and post that here too.
