Hi Ricardo, Make sure the value of the uuid is the same across all the nodes in a cluster and that it is preserved across upgrades.
It turns out the uuid value doesn't have to be an actual uuid, it could be for example the hostname of the cluster as long it is expected to say stable and not change.
