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.
