I can no longer validate my federated ArcGIS Servers in Portal 10.5. When I do this I get red exclamation marks. I'm trying to track down the cause of the issue and have started looking at the datastore. I can publish map services from Pro however I don't seem to be able to publish hosted services. When I run the describe datastore utility the relational data store status is RecoveryFailed, while the tile cache datastore status is Started.
I'm assuming that the relational datastore status should also be started. Any ideas on how I restart / repair the datastore ?
