When building a NAS, lately my OS of choice has been OpenMediaVault. Unfortunately, OMV doesn’t ship with native support for one of the most inexpensive SAS controllers, the HighPoint RocketRAID 2720GSL. To gain support for the controller, you have to backport your Kernel. The process will take only a few minutes and is easy enough for a novice to do.
First, you have log into your OMV server and make sure SSH is enabled (with root login). Open up a web browser and point it to the IP address your OMV grabbed (you can see in the screenshot above). In my case, it was 192.168.1.27 (the first available IP address). The default username is admin and the default password is OpenMediaVault.
- Click on SSH in the left menu panel
- Check the box for Enable
- Ensure the box for Permit root login is checked
- Click OK
Next, grab your favorite SSH utility and SSH into your OMV Server.
Log in as root and use the password you set during the installation
You need to add the source for the new kernel
add the following to the end of the file (move your mouse to the end of the file, copy the line below then right click in the putty window to paste it)
deb http://backports.debian.org/debian-backports squeeze-backports main non-free
Press CTRL-X to exit, confirm when prompted by hitting Y and save by hitting Enter
Update with APT
See what kernel is available
apt-cache search linux-image-3
Install the kernel (taken from the information above – change the line below should yours reflect something different)
apt-get -t squeeze-backports install linux-image-3.2.0-0.bpo.4-amd64 firmware-linux-free firmware-linux-nonfree
Press Y when prompted to continue
If you are prompted that Required firmware files may be missing, press OK – be patient, this may take a bit to finish
Reboot to finish the update by typing
