All databases marke out of service in cluster

Hi

having just set up a cluster, I am trying to set a couple of our larger databases as out of service so users failover to the replica. The problem I have is that every database I look at in the admin client using Files/database/Cluster has Out of service checked. This is not the case as they work fine. If I change it to in service - it processes the change but when I go back in, it says Out of service again.

I’m just about fed up with Clustering after four days and many problems. If someone can give me an answer to this I would be grateful. Also, while you are here, if you know why my availability index is so low when the server itself is at 89% idle I would be most ecstatic.

thanks in advance
