Yes, even LVM has the 2TB limit at this point. This is because LVM
presents itself to the rest of the kernel as a block device (just like
any other), so the kernel 2TB limit for block devices still holds.
Heinz talked about allowing LVM to have PAGE_SIZE (4k) blocks (unlike
the rest of the kernel, which uses 512 byte blocks) so it may be possible
to go up to 16TB with LVM without a huge amount of kernel redesign.
Cheers, Andreas
