Open Stack

After doing live migrations for some instances, and those migrations failing, the attached volumes show duplicates of the same attachment. 
This is the error message I get when the migration fails:
https://pastebin.com/raw/3mxSVnRR

openstack volume list shows the volume is attached to the instance twice.

How do I remove the duplicate attachment, and why could the live migration be failing in the first place? Not all migrations fail, but sometimes they do and I have multiple volumes with duplicate attachments.
