These are independent plays, not a role yet, can you change that!

This comment talks about plumbing this into the playbook:

  • So, currently this is run as an independent play, which would need to be integrated to the global playbook and roles (site.yml and possibly the common role)
  • This configuration is setup specific, which means a setup-profile declares intent that it needs an IPv4 address configured with said parameters
  • The above part of the plumbing is achieved, by adding a variable to each host in the setup-profile (for such a setup), lets use the same naming convention as the IPoIB and call this, "confipv4addr" (so this will be of the form confipv4addr:
  • The presence of this variable should trigger the configuration play setup_10g_nic.yaml, which can be achieved using a similar pattern to the check, https://github.com/gluster/gbench/blob/master/ansible-playbook-base/roles/common/tasks/main.yml#L16

The above would complete the required plumbing to run this play as part of the playbook, when a setup deals with only IPv4 addresses, and needs one setup for it.

for dev in $(ls /sys/class/net/)
do
link=$(ethtool ${dev} | grep "Link detected: yes" &> /dev/null; echo $?)
if [ $link -eq 0 ]
then
speed=$(ethtool ${dev} | grep "Speed: 10000Mb/s" &> /dev/null; echo $?)
if [ $speed -eq 0 ]
then
export MY_NIC=${dev}
break

MY_IP here would be replaced with the variable confipv4addr when defined in the setup-profile, like,
https://github.com/gluster/gbench/blob/master/ansible-playbook-base/roles/common/tasks/ipv4oib.yml#L8

Assume above 2 lines will be removed, as they are not a part of this play.

ping -c 1 ${MY_IP}
if [ $? -eq 0 ]
then
exit 0
else
exit 1

I am not clear what this play does. I assume each server should have its hosts file updated with the others. I would suggest we use ansible templates and copy them over to the servers, than running a script.

Also if you can let me know what the variables are, and where they come from, we can talk about how to plumb them as well through ansible variables.

- hosts: servers
tasks:
- name: Configures the first 10G nic with an active link
shell: |
echo "" >> /etc/hosts
x=1
for node in $MASTERNODE $NODE
do
echo "$(echo $IP_LIST | cut -d " " -f ${x}) $(echo ${node} | cut -d "." -f 1)-priv.css.lab.eng.rdu2.redhat.com $(echo ${node} | cut -d "." -f 1)-priv" >> /etc/hosts
x=$((x+1))
done
