Patching S2D clusters is a common question. This first part covers offline patching—shutting everything down, patching all nodes simultaneously, and starting back up—with scripts like Stop-S2DCluster and Start-S2DCluster to automate the process.

Improper maintenance mode is a top cause of S2D failures. These three PowerShell functions—Get-S2DNodeMaintenanceState, Enable-S2DNodeMaintenance, and Disable-S2DNodeMaintenance—make it easy to do it right.
