[dm-devel] dm-linear error: Device lookup failed

[Mark Huth]

Hi,
I am encountering the following error/message whilst the machine is
booting up:

kernel: device-mapper: 4.5.0-ioctl (2005-10-04) initialised: dm-
devel at redhat.com
kernel: device-mapper: dm-linear: Device lookup failed
kernel: device-mapper: error adding target to table
kernel: device-mapper: dm-linear: Device lookup failed
kernel: device-mapper: error adding target to table
kernel: cdrom: open failed.
last message repeated 2 times

I am not using LVM (just a bunch of raid0 partitions) so it seems that
this error is more informational rather than a sign of possible
problems, and the system seems to otherwise be functioning normally.  So
I was wondering if anyone on this list can confirm that it is nothing to
worry about and if there a way to make the system happy to prevent this
message from showing up.  I am using RHEL4U3 (kernel 2.6.9-34.EL).

Thanks,
Mark
