Thanks for the enlightment.
I manage to get the driver from the modules.gz archive and i made a new
initframs using dracut --add-drivers but modprobe still cannot find it,
possible that the module will indeed not work :/
The error is saying :
could not insert 'rr272x_1x' : Exec format error

The driver was built incorrectly for this version of the system. Just
why, I don't know. It did get put into the correct directory or
modprobe/insmod wouldn't find it at all.

Did i miss something? the driver is a .ko file

Just because it's a .ko file doesn't mean it's compatible with a 4.x
kernel. Odds are that it isn't. You should browse High Point's web
site and see if there IS a version of that driver that's 4.x compatible.

Sorry I can't be of more help.

        updating this, i did some testing on the sh file and i found
        where the
        issue is coming from.
        There is two for loops (at least two that concerns me) and the code
        inside is never executed.
        Condition is :
        for dir in [23].*;do
            [ -d $dir/kernel/fs ] || continue

        I'm a bit lost here, what is this 23 number? it cannot be fedora
        number
        as this driver is the open source version of the fedora 17 driver.
        Pretty sure if i modify the condition with a correct one everything
        should work properly


    F17? Well, that's probably the issue. What you're seeing is an attempt
    to walk down the various /lib/modules/2.* and /lib/modules/3.* trees
    to install the driver. If you're on F22 or F23, you probably don't HAVE
    2.* or 3.* kernel trees. You have 4.x kernel trees.

    You could try changing that line from:

             for dir in [23].*; do

    To:

             for dir in [234].*; do

    That would include the 4.x kernel trees. I don't know if the module will
    work, though as it seems to be written for quite old kernels. YMMV

             Hello guys, got this weird error trying to install my raid
        driver :

             Start to install the driver rr272x_1x.ko of rr272x_1x.
             Finish installing the kernel module rr272x_1x.ko.
             Loading rr272x_1x driver module rr272x_1x
             modprobe: FATAL: Module rr272x_1x not found.

             Checked with lsmod driver does not appear tough the
        installation is
             finished (checked the sh file, modprobe is running at the end).
             After a little read of the sh file i can confirm that the
        driver is
             in /etc/rc.modules (it appears to be with sd_mod and that's
        all).
             chmod on rc.modules in the sh file is successfull (chmod 755).
             The failing part seems to be this :

             elif [ "${MODULE}" = "rr272x_1x" -o "${MODULE}" =
        "rr274x_3x" -o
               "${MODULE}" = "rr276x" -o "${MODULE}" = "rr278x" ] ; then
             ( cd /lib/modules/
             for dir in [23].*; do
             [ -d $dir/kernel/fs ] || continue
             if [ -f /boot/initrd-$dir.img ]; then
             mv /boot/initrd-$dir.img /boot/initrd-$dir.img.bak
             # do not include mvsas in initrd, as the udev and so will
        load the
             driver
             mkinitrd --builtin=mvsas /boot/initrd-$dir.img $dir
             elif [ -f /boot/initramfs-$dir.img ]; then
             mv /boot/initramfs-$dir.img /boot/initramfs-$dir.img.bak
             # do not include mvsas in initramfs, as the udev and so
        will load
             the driver
             dracut /boot/initramfs-$dir.img $dir
             fi
             done

             Can someone give me a hint on how to do what needs to be
        done? I'm
             not familiar with drivers on unix systems so i'm a bit
        lost, full sh
             file is attached if needed, thanks.
