I have developed my own TM driver for a NFS based datastore using ZFS. It works

Hi,
I believe you should be able to do this by creating a custom datastore driver.
I have a use case which is not too different than you. I created a 'localfs'
datastore & transfer driver which is able to create images on a specific host,
utilizing local disk storage (for performance reasons).
Assuming there is space left in the LVM VG, you should be able to use lvextend
to add a bit of extra storage to that volume so the deployment can succeed.
Something like 'lvextend -L + 100M '
