Share a persistent disk between Google Compute Engine VMs

Question

Persistent disk is present in read-write mode and i am trying to attach the disk to subsequent instances, GCE returns an error. I need to have a share persistent-disk as frontend to  my compute engine, good, how can we write on this shared disk?

Does this flow can be achieved with 2 Compute Engine VMs and 2 persistent disks?

VM1 read/write disk1 and read only disk2

VM2 read/write disk2 and read only disk1
