How to take S2D disks out of maintenance mode

Question

We have a three-node storage space direct hyper-converged cluster running Windows Server 2022 and we are having difficulty taking the disks out of maintenance mode after the server was patched.

The following command does nothing:

Get-StorageFaultDomain -Type StorageScaleUnit | Where-Object {$_.FriendlyName -eq "<NodeName>"} | Disable-StorageMaintenanceMode

it shows a new line and does not error out but the disks remain in the same state - How can we take the disks out of maintenance mode?

Hi ppinfrageek,

Thanks for your post. It seems that the S2D has stuck in maintenance mode. Please try the following methods and see if it works.

1. Repair-ClusterS2D -DisableStorageMaintenancemode

2. If you are certain it is not an issue and just cosmetic / false labellin

you can clear the flags to set your disks to show 'OK' in the Windows Admin Centre.

We were experiencing this exact issue where the WAC was showing 'Stopping maintenance mode, OK' however checking Get-StorageJob, Get-ClusterStorageSpacesDirect + Get-StorageHealthReport, Get-PhysicalDisk from PowerShell which stated disk operational status as OK and no jobs running so presumed this was cosmetic from the WAC. The step involved importing a PowerShell script, identifying the disks concerned and repeating a command for each affected disk. The script to import is called 'Clear-PhysicalDiskHealthData.ps1' downloadable from https://go.microsoft.com/fwlink/?linkid=2034205 .

You can then run Get-PhysicalDisk | Select-Object SerialNumber,UniqueID to show all your disks IDs. Once you have the ID of the disk you want to resolve run Clear-PhysicalDiskHealthData -Intent -Policy -UniqueID xxxxx -Verbose -Force (replacing xxxxx with your disk ID.
