Comment 2 Martin Schuppert 2021-03-19 09:39:35 UTC 
DiskFilter and RamFilter was removed in train, NovaSchedulerDefaultFilters in the environment file needs to be updated to remove those.

https://docs.openstack.org/releasenotes/nova/train.html#relnotes-20-0-0-stable-train-upgrade-notes "The CoreFilter, DiskFilter and RamFilter, which were deprecated in Stein (19.0.0), are now removed. "

This BZ should be used to track a tripleo-validations check for that.
