Failover Cluster can’t access when Disk Quorum witness is outage

The problem is when the disk quorum witness is full, we cannot expend or do anything.

Here is the solution that we did;

1. The "disk quorum" which is offline -> we remove it from the "Failed Cluster Manager"-Storage-Disks- Disk quorum- right click remove

2. In my case : the disk is "Disk 1"

PowerShell command:
Clear-ClusterDiskReservation –Disk

In my case : Clear-ClusterDiskReservation –Disk 1

Then, resize the harddisk by making it online -> right click-> extend

Finish -> then right click -> offline the hardisk

3. Then add back the disk (Add Disk) to the cluster storage;

4. Then configure cluster quorum settings ->  use default quorum configuration setting.
