I have a persistent disk of 100GB attached to a VM instance. But I don't need all that space, and thus don't want to be billed for it. It has some data as well. I took a snapshot of the disk, and tried to create another one.
While trying to create a new one, it wouldn't take a value less that 100GB and says, since the snapshot is also of 100GB, the new disk should have a minimum size of 100GB.
How can I make a smaller persistent disk from a snapshot? Or reduce the size of the existing one?
