Then you really should read more about LVM and experiment it before 
installing a system on LVM.

What do you mean ?
Did you allocate all the available space in the volume group to the 
logical volumes ? Creating snapshots requires space.

When installing with LVM, an important rule is to always leave plenty of 
free space in the volume group. Don't worry, extending a logical volume 
when needed is easy. This implies to use manual partitioning, because 
guided partitioning allocates all the available space.
