Dear list,

We've recently faced an issue regarding live migration on a Juno openstack
installation using a ceph giant shared storage.

The error that appear is

DestinationDiskExists: The supplied disk path
(/var/lib/nova/instances/instance-id-hidden) already exists, it is expected
not to exist.

I've located several entries, such as:


But the error still persist and some of the patches have already been
included. The current version is the following:

Name        : openstack-nova-compute
Version     : 2014.2.1
Release     : 1.el7.centos

It looks like there's an issue regarding shared storage and the assumptions
of this path.

Can anyone provide information about this issue?
