You need to have 0.9 version tools to run with the 2.4 kernel.

Never good to bet your job on things you have not tested.  That way
leads to a new job.  LVM has been _fairly_ reliable, but there have
also been some problems as well - most have been fixable with a bit of
debugging, but...  It is always worthwhile to do testing before putting
a system into production.  Note that you have a far smaller chance of
having serious problems if you ensure you make backups of your data,
and make as few changes to your LVM configuration as possible.

I have never had problems with LVM that I didn't cause myself from
working on the code.  But then again, none of the data I have under
LVM is critical (mostly MP3s and test filesystems), and I have full
backups of everything.

Cheers, Andreas
