I'm using several Windows Server 2019 Clusters (e. g. Hyper-V, File Server). On all machines that have clustered roles, I get the following errors (with different harddisk numbers):
Log Name: System Source: Disk Event ID: 11 Level: Error Message: The driver detected a controller error on \Device\Harddisk1\DR1.
From my observations, I can conclude, that the error is always thrown on harddisks that are currently offline on one cluster member, because they are online on another cluster member. So it happens on disks that are used by cluster roles for data and disk witness in quorum.
I'm not sure, if that's just ok in this case and that I can ignore those errors or if there is some misconfiguration and something has to be fixed.
Can someone confirm, that this is normal behaviour or that something might be broken?
