/proc/misc: No entry for device-mapper found Is device-mapper driver missing from kernel?

This is a bit of an irritating error, with a simple solution:

/proc/misc: No entry for device-mapper found Is device-mapper driver missing from kernel? Failure to communicate with kernel device-mapper driver. Added Linux *

First of all, we need to make sure that our kernel configuration has Device Drivers->Multiple devices driver support (RAID and LVM) compiled in, with Device Mapper Support as a module.

Once device mapper support is compiled in as a module, if we still receive the error, we can run:

sudo modprobe dm_mod
sudo /sbin/lilo

The errors should now be gone:
