Does disk space required in compute node when launch instance from block storage?

My setup is like 1 controller, 3 compute(each 50GB disk) and 1 cinder storage.. I'm lunching instance from cinder volume. While launching instance does it check disk space available in compute node.

Example I have created 100GB bootable volume and launched as instance, But compute node have only 50GB. Does this instance launch successfully?
