I am not making the changes within chef they have been done outside chef.
Thanks for the debug info. Although it has not helped me out.
If I explain the exact steps, I am taking, it might make things easier
The network names have been changed by editing the ifcfg-NAME files. A
network name routes specific file has also been added for all new
interfaces. The OS is Red Hat Enterprise 5
An ifconfig lists the updated names and IP addresses.
Running ohai on the server I can see the new network card name in the
network json object. (network[:interfaces])
In my chef recipe I am going through each node, except the logserver,
pseudo code below:
servers = search (:node , “(NOT role:logserver)”)
servers.each do |server|
Code here that fails as it can’t find the network name in the above
- I am expecting to see printed out above the exception the network names
which ifconfig and the ohai command line app are reporting. However I am
seeing the original eth0, eth1 names.
If ohai does not cache any information, what else could be going on? I
have restarted chef-server, but that had no effect.

I initially setup the server the network names were just the standard
But I have now changed the names of the network interfaces to make things
easier for me to track different networks and their connections.
Are you making these changes with chef and wish to see them reflected
within the chef run?
However even though I have restarted the network interfaces and doing an
ifconfig brings up the correct names, when trying to get the ip address on
new names, it fails. After some debugging it turns out that it is still
referencing the old network adapter names.
Is there a way to flush the ohai cache or tell it to get that information
Ohai doesn’t have a cache. It’s information is fully refreshed on every
chef run. If you need to refresh it within a chef run, see the ohai
If you need to debug what ohai is doing, you can run
ohai -l debug on
the command line.
Thanks in advance.
