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 -----

What I tend to do these days is that if I don't have multipath or might start using multipath somewhere in the future is to blacklist all devices and then whitelist the real multipath devices when needed. amend /etc/multipath.conf with this: blacklist { wwid "*" } Joop
