We have three hyper-v host server (windows 2012) in cluster environment. We have SAN which is mounted as cluster-storage on all three server. Hyper-V1 has ownership of the disk.

Recently we increase the disk space on SAN volume and it reflect in the cluster disk but not in the cluster volume. It shows the correct size in the disk management on all servers, but does not show in the cluster-storage.

Please see the attache screenshot to understand more clearly.

Can someone help me how can I resolve this issue?

Thanks

I followed the same steps, it shows when we first time extended the disk in clusterstorage, but after a while it revert back to previous capacity.

Did you check on all the three nodes and refresh or re-scan disks in disk management?
