    Question Complete install on RAID1 + LVM?

    I was doing a bit of research to see if this was possible. I wanted to install the entirety of Ubuntu (desktop), including /boot and everything on LVM on top of software RAID1.
    Code:
    sda | sdb   sdc | sdd 
        |           |
      RAID1       RAID1   
              |
             LVM
      |   |   |     |
    /boot / /swap /home
    Hopefully the above shows what I want to do (ignoring lack of fs). I am currently unsure whether this is possible because of old documentation that seems to present conflicting information. I don't really care if it isn't possible but I am very interested.

    It should be. Earlier you had to made /boot partition outside the LVM so it can work, but grub2 these days can handle LVM without separate /boot outside the LVM.

    So, making two raid1 mdadm arrays, and then using them as physical devices for your LVM should be just fine.

    You can also do a test in VBox first.

    Excellent! Thanks for the response. I figured it was doable but there is so many conflicting opinions around the place. My understanding was that it is achievable with grub2 as it can see the RAID + LVM from the MBR.
