Public bug reported:

Hi.
I found a bug over the service multipathd used by Cinder-Volume.

When I attached a volume in a instance, it has wrong size. Then I went to see logs from compute node owner of that volume path and I could see the wrong path, from another volume, was delivered to the instance.
The mapper had 4 right paths, from 4 iSCSI ifaces from our Storage, but too 2 fault paths, that belongs to another volume from same Storage.

Cinder volume version = 19.1.8

Openstack version = Openstack Ansible Stein

** Affects: cinder
     Importance: Undecided
