Cluster Aware Updating Corruption

Hi everyone!

We're getting the below error when a CAU run occurs for one cluster in particular (all the other clusters are fine).

CAU run {00000000-0000-0000-0000-000000000000} on cluster vc11 failed. Error Message:The data stored by the Cluster-Aware Updating cluster resource is corrupt. The name of the corrupt data is: CauRunState. Error Code:-2146233088 Stack:   at MS.Internal.ClusterAwareUpdating.CrmRunStateManager._LoadState()   at MS.Internal.ClusterAwareUpdating.CrmRunStateManager.<InitSessionStateAsync>d__3b.MoveNext()--- End of stack trace from previous location where exception was thrown ---   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)   at MS.Internal.ClusterAwareUpdating.RunStateImplBase.<InitSessionAsync>d__4.MoveNext()--- End of stack trace from previous location where exception was thrown ---   at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)   at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)   at Microsoft.ClusterAwareUpdating.Commands.InvokeCauRunCommand.<_ProcessCluster>d__78.MoveNext()

We have tried removing the cluster role and re-creating it, but the same thing occurs.

I can't find anything else online relating to this corruption error.

Any ideas?

Thanks!
