Hi Jorick, This error is most often caused by multipath attempting to map a device which is already in use, such as if its mounted or mapped by an active LVM logical volume. If the blacklist in /etc/multipath.conf does not restrict multipath from mapping the device, then when it gets run during boot it will attempt to map it. Because the device is in use, this mapping will fail. Have you tried the blacklisting procedure mentioned at comment 3 in the bug? https://bugzilla.redhat.com/show_bug.cgi?id=675366#c3 ----- Original Message -----

Hi,
I'm seeing a continuous stream of multipath errors on my Centos 7 hosts with ovirt 3.5 rc1.1.
Can't find a bug for it except https://bugzilla.redhat.com/show_bug.cgi?id=675366

Kind regards,
