Well not sure how helpful I’m going to be here as I’m not sure I quite understand your problem, but a few things:
Ohai (at least as of 0.5.6) merely runs a hostname -s for node[:hostname], hostname --fqdn for node[:fqdn] and for node[:domain] takes the fqdn value and chops the string to the first dot. So whatever changes you make, you can test them with those two commands to see if you’ve fixed anything.
In general (someone chime in if I’m incorrect):
short hostname goes in /etc/hostname
fqdn goes in /etc/hosts along with the short hostname with either localhost address or the primary IP of the server (I prefer primary IP, but example below is localhost)
127.0.0.1 server.domain.com server
Make sure you dont reverse those.
Now I’m not sure how slicehost bootstraps servers… Making the changes above should give you the correct responses from the hostname command, but only after a reboot. You may still need to experiment with the hostname command or changing /proc/sys/kernel/hostname and/or /proc/sys/kernel/domainname to do it without rebooting.

Machines are slicehost vms. How they get their fqdn goes like this:
- A new machine is added through slicehost panel, I give it a simple name like app01.
- The machine is based on a image that has a chef-bootstrap script on init. This script runs only on first boot, installs ruby, rubygems, chef, sets the fqdn and then registers the node on the opscode platform. This is the relevant part of the code
HOSTNAME=hostname
DOMAIN=foo.com http://foo.com
echo " - setting hostname to $HOSTNAME.$DOMAIN."
echo $HOSTNAME.$DOMAIN > /etc/hostname
sed -i s/$HOSTNAME/$HOSTNAME.$DOMAIN/ /etc/hosts
hostname $HOSTNAME.$DOMAIN
At this moment the machine does not have dns entries associated with it, but if I this is a requisite I can work it out.
Also its ip address not assigned via dhcp (see above).
Thanks.

How do you get your IP and domain? Are the machines assigned via dhcp? Do the ip addresses have reverse entries with the proper fqdn?

Hi chefs,
I’m having lots of problems when setting fqdn on ubuntu 10.04 nodes so chef gets the fqdn right.
If I run ‘hostname fqdn’ hostname returns fqdn but hostname -f does not, and the node gets registered with just the machine name.
The only way I found to make chef get the fqdn is adding an entry to /etc/hosts with the ip address and the fqdn on the machine. I haven’t had this problem on ubuntu 8.04 nodes.
I’d like to find another way to make this work than editing /etc/hosts before chef register nodes.
Has anyone had this problems?
Greetings.
