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
