Use verify_on_create when creating pacemaker remote resources
We currently create remote resources without waiting for their creation.
This leads to the following potential race (spotted by Marian Mkrcmari):
- On Step1 pacemaker bootstrap node creates the resource but the remote
resource is not yet created
- Step1 completes and Step2 starts
- On Step2 the remote node sets a property (or calls pcs cib) but the
remote is not yet set up so 'pcs cluster cib' will fail there with:
(err): Could not evaluate: backup_cib: Running: /usr/sbin/pcs cluster
cib /var/lib/pacemaker/cib/puppet-cib-backup20170506-15994-1swnk1i failed
with code: 1 ->
Note that when verify_on_create is set to true we are not using the cib
dump/push mechanism. That is fine because we create the remotes on
step1 and the dump/push mechanism is only needed starting from step2
when multiple nodes set cluster properties at the same time.
Tested by Marian Mkrcmari successfully as well.
