We had a reported Bug 1656124 where this clone was made of it and the issue was resumed here:
In THT, we construct data to be passed to novajoin for all the services to be configured. The data is passed as nova metadata fields.
* There can be any number of these fields, but each field cannot exceed 256 bytes.
* In particular, the services on a controller not related to a VIP are passed in a field called "compact_services"
* If there are additional services added (as ODL does), we can exceed the 256 byte restriction.
To fix that we needed two changes, one on the tripleo-heat-templates where it was fixed on openstack-tripleo-heat-templates-9.0.1-0.20181013060906.el7ost and we also needed a novajoin rebase for python-novajoin-1.0.22-1.el7ost.
This BZ only makes sense to be fixed with both changes land in the same puddle, that the reason why we're moving this BZ for GA.
