vRA Action - Create Snapshot - Size calculation

hi all

Can any of you confirm this behaviour or have any further information?

A user has tried to take a snapshot of a VM in the vRA portal which failed with the following message:

CreateSnapshotError: Reservation with name XYZ does not have enough resources to create a new snapshot for machine with name ABC and ID 123.

This makes sense for me, because the VM is 2200GB and in the reservation the corresponding datastore has only 1300GB free space.

vRA will probably take the maximum snapshot size and check it with the free space on reservation. Can anyone confirm that?

And is there a way to disable this check?

What I don't really understand is that the snapshot was taken in vCenter, although the request is failed in vRA.

Thanks.

Andi
