Hi,

the output shows that you were able to create a volume group.

It looks like you don't have the LVM driver set up properly though
which is necessary to activate your volume group in order to proceed
and make logical volumes.


Did you follow the instructions in PATCHES/README contained in the LVM
tarball to patch your kernel and build the driver?

Did you activate the LVM driver in the kernel configuration?

It doesn't matter in principle if you choose driver or module during
kernel configuration.

If you choosed module: did you load the module or configured the module
                       loader to do it?


BTW: I recommend that you get the actual LVM software 0.9.1 Beta 7 from
     www.sistina.com/lvm before you retry, because it fixes some bugs
     you otherwise would still have with 0.9.1 Beta 5.
