Ubuntu Software Installation

To use AoE in Ubuntu you can use the Ubuntu packages that provide AoE functionality. There is an Ubuntu page here describing how.

Driver Installation

If you have a special reason for using the software from the Coraid website instead of the Ubuntu packages, you can install the Ubuntu packages that will allow you to build third-party drivers for your kernel.
sudo apt-get install build-essential linux-headers-`uname -r`

The standalone aoe driver from the Coraid website determines where to install the aoe module by using the Makefile in the kernel sources. On Ubuntu, the module installation directory from the kernel sources doesn't match the running kernel.

You can easily specify the location where the aoe module should be installed by adding it to the "make" command line. Instead of just doing "make install", you can do ...

make install INSTDIR=/lib/modules/`uname -r`/kernel/drivers/block/aoe

Modprobe Configuration

An Ubuntu user reported that Ubuntu doesn't use /etc/modprobe.conf directly, so to install the standalone aoe-2.6-10 driver, he performed the following steps after changing directories into the unpacked aoe-2.6-10 sources.

Note that you should only perform these steps if you don't already have an /etc/modprobe.conf file and your ubuntu system is using /etc/modprobe.d/aliases.

touch /etc/modprobe.conf
make install INSTDIR=/lib/modules/`uname -r`/kernel/drivers/block/aoe
cat /etc/modprobe.conf >> /etc/modprobe.d/aliases  # append it

It would be good to tidy up by removing the /etc/modprobe.conf file now, because it isn't really the definitive database for kernel modules.

Minor Device Numbers

Support for minor device numbers greater than 255 seems to be lacking in Ubuntu 5.04.

root@makki:~/aoe-2.6-11 # mknod /tmp/testdev b 152 256
root@makki:~/aoe-2.6-11 # ls -l !^
ls -l /tmp/testdev
brw-r--r--  1 root root 153, 0 2005-08-11 15:55 /tmp/testdev

Please see the EtherDrive 2.6 HOWTO's FAQ for more information on this issue.
