After patching both our S2D clusters today, i have had the same error after resuming nodes and failing back roles. This happens after installing KB4038782

Update, after installing CU10 october patch. Rebooting a S2D node will not cause this issue, after the initial update boot.

The Physical disk’s stays in maintenance mode.

To fix this, run the following command

Repair-ClusterS2D -Node NodeName -DisableStorageMaintenanceMode
