LVM2 is metadata and command line compatible to LVM1 plus it adds some nice
features such as a configuration file with various sections for device name
filtering and more.
You have the choice with it to upgrade your metadata to a more redundant format2
which causes updates to the metadata to be transaction oriented therefore
enhancing the online recoverablilty of the LVM system.
We still declare LVM2 to be in Beta _because_ it misses the soon to be added
feature to online relocate data (pvmove).
It is stable and you should give it a try :)
