ConfigStoreRootPath & SharedStoragePath Path Change
Both the ConfigStoreRootPath and SharedStoragePath locations under a hyper-v cluster cannot currently be amended after they are initially set so if you move the cluster storage to another storage array with different volume names you either have to:
1.) recreate the whole cluster to change locations of these values.
2.) rename the volumes to the old paths and then change all corresponding virtual machine paths or
3.) Create a small volume with the same name and path as already set for both ConfigStoreRootPath & SharedStoragePath.
It seems completely bizarre that such a well documented limitation has not be addressed by Microsoft and needs to be fixed.
