for the pass two weeks I get unexpected and random turn off, migration and shutdown of nodes on a 3 nodes Windows 2012 failover cluster on Dell hardware and EMC data storage. I find an error in the logs but cannot find what is causing this and why.
Event 1146, FailoverClustering
The cluster Resource Hosting Subsystem (RHS) stopped unexpectedly. An attempt will be made to restart it. This is usually associated with recovery of a crashed or deadlocked resource. Please determine which resource and resource DLL is causing the issue and verify it is functioning properly.
