I have a cloud with 8 nodes with volumes on the local hard discs. I now attached a external RAID to one of the nodes and added that as another backend in cinder with a dedicated volume type. Creation and use of volumes on the RAID work fine. So i tried to start a live volume migration to that backend as described http://docs.openstack.org/admin-guide-cloud/content/volume-migration.html (here). However the migration stays in the state "migrating" (os-vol-mig-status-attr:migstat) since 2 days without anything else happening. Can i abort the migration? How? What is going wrong? The cinder-* logs don't give any information on that.
