AoE on CentOS

here are my notes on installing an AoE server (vblade) on a CentOS 5.3 host:

 su -c 'rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-3.noarch.rpm

then install yum-priorities, set priority=22 or so in /etc/yum.repos.d/epel.repo

(move this to 3.3 not needed)

wget http://superb-west.dl.sourceforge.net/sourceforge/aoetools/aoetools-30.tar.gz

yum install vblade tar -zxvf aoetools-30.tar.gz cd aoetools

yum install gcc make all install

(no idea why CentOS has vblade but no aoetools? maybe a

vblade in epel doesn't have udev stuff

http://superb-west.dl.sourceforge.net/sourceforge/aoetools/vblade-19.tgz

in /etc/udev/rules.d/60-aoe.rules

SUBSYSTEM=="aoe", KERNEL=="discover",	NAME="etherd/%k", GROUP="disk", MODE="0220"
SUBSYSTEM=="aoe", KERNEL=="err",	NAME="etherd/%k", GROUP="disk", MODE="0440"
SUBSYSTEM=="aoe", KERNEL=="interfaces",	NAME="etherd/%k", GROUP="disk", MODE="0220"
SUBSYSTEM=="aoe", KERNEL=="revalidate",	NAME="etherd/%k", GROUP="disk", MODE="0220"

# aoe block devices     
KERNEL=="etherd*",       NAME="%k", GROUP="disk"

note how the equality tests are == and the assignments are =  ? note that the kernel documentation is wrong for redhat in this regard.
