VM files are crashed & not booting again

I am having 4 Node Scale IO with proper MDM primary & secondary , SDS .  in that 2 Nodes are SDS as well as SDC 1 TB LUN Assigned and may VMs are running (HyperV Cluster)

I had rebooted one by one - Everying is fine forward & reverse rebuild and there was no issues.

But when I rebooted 2 node at the same time data corruption occurred.

I understand if no of node failure is exceeding, data will not be available.
But in that case Volume should be unavailable to SDC.
Since volume is available for SDC with half fault (some GB data was showing failed capacity)Data , VHDx is crashing (Os Showing Blue screen after few min) .
For Inactive data (files) there is no problem , as soon node comes back data visibility is fine(there is no problem with object data).

I just want to set when maximum node down and if there is fault space in volume, that volume shouldn't be accessible by SDC. So VM will go off but wont crash the file .
