[linux-lvm] lvmcreate_initrd failing...not sure why

I am trying to convert my root file system over to LVM (1.0.6 running on linux 2.4.20).  I have read the LVM-HOWTO cover to cover several times, but I seem to be having trouble with lvmcreate_initrd.  Attached is the output when I run lvmcreate_initrd -v.

Does anyone have any idea what is happening?

Don't. All you do is make it difficult to recover from LVM
problems. If you mount the major filesystems (including
/usr and /var) as LV's / only needs to be around 80MB
for /bin, /lib, /etc, and /boot. For the minimal amount
of space you use, why bother with it?

Well, I have read that this is usually the best case before.  But it is more just something I would like to do, not that I feel I need to.  It *is* possible, right?  My system isn't mission critical and LVM is something I have never messed with before, so I figured why not go all the way and just use all my disks as PVs.

Your recommendation would be to keep root and swap out of LVM, and just mount /usr /var /home as LVs?

Any idea why lvmcreate_initrd was failing?

I normally leave / on a partition, maybe /scratch, maybe
primary swap (most systems today don't swap enough to make
it worth the diffrernce). My sandbox area is mounted under
/sandbox, which is also on LVM, along with any database
areas.

Only point is to keep the root volume small enough that it
doesn't need to grow, which means it can conviently be put
onto a partition.
