I've since learned that I have to use hiera_array and hiera_hash,
which aren't documented anywhere.
Now I've got:
ec2_config:
instance:
m1.small:
pvdisks:
- /dev/xvdb1
swapvol_size: 2G
logvol_size: 64G
m1.medium:
pvdisks:
- /dev/xvdb1
swapvol_size: 2G
logvol_size: 64G
m1.large:
pvdisks:
- /dev/xvdb1
- /dev/xvdc1
swapvol_size: 4G
logvol_size: 64G
and I've tried to access the data every witch way.
This gives me a syntax error...
$pvdisks = hiera_array(ec2_config['instance'][$::ec2_instance_type]['pvdisks'])
and this:
$pvdisks = hiera_array($ec2_config['instance'][$::ec2_instance_type]['pvdisks'])
gives me:
err: Could not retrieve catalog from remote server: Error 400 on
SERVER: ec2_config is not an hash or array when accessing it with
instance at /truth/sauce/env/prod/modules/role/manifests/base_server.pp:27
on node gfs01.us1.xxx.com
Ugh.
Doug.
