I've discovered that this issue is due to b353792f9c/cluster/gce/util.sh (L579)

default incr is -1.

Allow log-dumping only N randomly-chosen nodes in the cluster
This should let us save "lots" (~3-4 hours) of time in our 5000-node cluster scale tests as we copy logs from all the nodes to jenkins worker and then upload all of them to gcs (while we don't need too many).
This will also prevent the jenkins container facing "No space left on device" error while dumping logs, that we saw in runs 12-13 of gce-enormous-cluster.
The longterm fix will be to enable [logexporter](https://github.com/kubernetes/test-infra/tree/master/logexporter) for our tests.
