Installed 0.4.0 and compile multipathd with DEBUG=3.
In multipath/Makefile

EXEC = multipath
DEBUG = 3
all: $(BUILD)
Multipathd: path checker startup happens for all devices as previously,
however nothing else happens.
Log ends here. Waiting for over 1 after one instance of the restart of
the multipathd daemon and nothing happen.
The following is displayed after the daemon is restarted though:

Setup DEBUG=3 in multipath/Makefile.
Few additional things:
The output of multipath -v2 is now:
Device mapper prerequisites not met.
I have hotplug-2004-09-23
Device-mapper-1.00.19
Multipath-tools-0.4.0
Kernel 2.6.5-7.111.5 (Could this be the problem?)
Also do I need to update the multipath.ko modules with a newer version?
I noticed it is the still the inbox default that is loaded.
Thanks
Aboubacar.
