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

You need a proper set of actions to increase shared LUN and CSV layered on top of it. Please see:
