Hi,

i could setup external access to the machine, but be aware that it 
consists of a chroot'ed 64bit hacked-together debian, so compiling 
something with 64bit isn't any fun at all. The 32bit userspace however 
is fine.

I tried to compile the lvmtools as 64bit, but the result didn't change. 
are there any points where i can put some debug printfs/printks in the 
sources to work out where it fails? I never looked at the LVM internals, 
so i don't know what happens where. Does the kernel space reads and 
parses the metadata? Or does the userspace parses it and passes it to 
the kernel?
