Open Stack

It is very strange.
Check nova.conf on both nodes to verify the instance path is the same.
Are you resizing an istance with a cinder volume or with ephemeral storage ?
I found another configuration issue when try to resize an instance with a
volume: libvirt chanche the ownership of the volume file.
Is this your case ?
