HI All,
I am attempting to set up a single controller overcloud with tripleo
Victoria. I keep running into issues where pcsd is attempting to be started
in puppet step 1 on the controller and it fails. I attempted to solve this
by simply removing the pacemaker service from my roles_data.yaml file, but
then I ran into other errors requiring that the pacemaker service be
enabled.
HA Deployment is enabled by default since Ussuri release[1] with [2]. So
pacemaker
will be deployed by default whether you set up 1 or more
controller nodes since Ussuri. Without pacemaker deployment is possible but
would need more changes(apart from removing pacemaker from roles_data.yaml
file), like adjusting resource_registry to use non pacemaker resources. HA
with 1 Controller works fine as we have green jobs[3][4] running with both
1 controller/3 controllers, so would recommend to look why pcsd is failing
for you and proceed with HA. But if you still want to go without pacemaker
then can try adjusting resource-registry to enable/disable pacemaker
resources
I have ControllerCount set to 1, which according to the docs is all I
need
to do to tell tripleo that I'm not using HA.
Docs might be outdated if it specifies just setting ControllerCount to 1
is enough
to deploy without a pacemaker, you can report a bug or send a
patch to fix that with the docs link you using.
Thanks,
James H
