sorted by: [ date ] [ thread ] [ subject ] [ author ] Hi Jorick, This error is most often caused by multipath attempting
Device Mapper Multipath Failing Path
to map a device which is already in use, such as device mapper multipath rhel5 if its mounted or mapped by an active LVM logical volume. If the blacklist in /etc/multipath.conf
Device Mapper Multipath Rhel6
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, https://access.redhat.com/solutions/38538 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 ----- > From: "Jorick Astrego"
