Multipathd does not compile, tar does not like the ../libsysfs stuff.  I
just changed it to use the system libsysfs until it gets fixed.

I'm using the 2.6.7 kernel with the multipath patches only (could that be a
problem?).

It's been a while since I've had a change to work with the dm multipathing
stuff.  While Multipathing work, it did not fair well when I pulled one of
the fibre cables out (basically it didn't work at all).  Does multipathd need
to be running (see below).

Multipathd does not run, it creates the pid file then exits (unless it's a
hidden process somehow).

How can I get the dm multipath stuff to work properly with devices that
already have a partition and fs on them? i.e I have sdb (and others that
point to the same device, I'll just use sdb to keep it simple) with 1
partition sdb1, I have a xfs filesystem on sdb1.  When I look in udev I see
dm-0, if I fdisk dm-0 it has a dm-0p1 partition in it.  I would have to
mount dm-0p1 right, or does that not work? but that device does not exist in the udev directory. 
Do I have to create my own dm table entry using the sdb1 entry?
