The only solution I know which allows for a configuration like this is using separate clusters in each data center, and using booth for transferring ticket ownership between them. Booth requires a data center-level quorum (meaning at least 3 locations), though the third location can be just a small daemon without an actual cluster, and can run in a public cloud or similar for example.
