Comment 1 for bug 1873940

This is an upstream bug with nova-compute, unrelated to openstack-ansible. Please file an issue with nova.

A quick search turned up a recent bug report that involving the same root cause (nova not handling cinder api timeout), but was only referencing detaching: https://bugs.launchpad.net/nova/+bug/1888665

You might want to file a new report there about the resize failure and reference that bug.
