I think one option should be to provide the user, if not already
present/tested/supported, the opportunity to resize the LUN on storage
array and then run a rescan from oVIrt to see the new size and use it
without disruption of service.
To avoid also LUNs proliferation on storage arrays that in general are
providing storage to many sources, also different from oVirt itself
