Subject: [PATCH 26/26] iotests: Mirror with different source/target size

RH-Author: Kevin Wolf <kwolf@redhat.com>

O-Subject: [RHEL-AV-8.2.1 qemu-kvm PATCH v2 11/11] iotests: Mirror with different source/target size
Bugzilla: 1778593
RH-Acked-by: Eric Blake <eblake@redhat.com>

This tests that the mirror job catches situations where the target node
has a different size than the source node. It must also forbid resize
operations when the job is already running.
