I have edited the readahead to 2048 for the root and my user.
So does anyone know why I get:

    FAIL (S0020): https://my.vertica.com/docs/7.0.x/HTML/index.htm#cshid=S0020
        Readahead size of
        (/dev/mapper/vg_fchyfx1-lv_home,/dev/mapper/vg_fchyfx1-lv_root) is too
        low for typical systems: 256 < 2048

    Hi Jesse,

    Are you using LVM? Vertica does not support LVM. If you are using community edition, and just want to get around this failure (assuming you fixed any other issues), you can run the install with: 
    --failure-threshold = HALT
    That will allow the install to continue and only stop on HALT issues.

    Hope that helps!
