If libvirt cannot write to the VM, it will be paused. Then several minutes later, the ovirt-ha-agent will realize they can't reach the status page of the engine and they will destroy and restart the HostedEngine VM. Then the engine will try to activate the storage domains and I'm not sure if it will be able to realize that the VMs were paused. At least it should fins your VMs paused and try to unpause them (as the storage domain has recovered). I think it will be safer, if you have another storage that you can migrate your VMs (temporarily) via storage migration and after the change - move them back if needed.
