Title:
Cannot attach to iscsi volume with multipath
Status in OpenStack Compute (nova):
Fix Released
Bug description:
This is Kilo specific (and works in Liberty, thanks to the move to os-
brick).
When attaching a volume, I'm seeing a failure like this:
Traceback (most recent call last):
File "/usr/lib/python2.7/site-packages/nova/virt/block_device.py", line

It turns out that the output of multipath -ll is this:

So we don't filter out correctly all lines; os-brick does this
correctly.
