There have been many bug fixes since that release.

First of all, try the last 2.01.* release (2.01.15) and see 
whether that fixes it.

Also suggest updating device-mapper to 1.01.05.

Check that you have in lvm.conf devices section:
  md_component_detection = 1 
(i.e. not = 0)

If you edit lvm.conf, run 'vgscan' afterwards.

If things still don't work, check your metadata backups
and archives in /etc/lvm and see if they show the LV
disappearing.  If you want me to investigate, tar up that 
directory and email it to me.
