(1)
download a "SystemRescue" system "iso", like for example:
https://sourceforge.net/projects/systemrescuecd/

boot for iso
(3)
find your partition that you want to check
-> for LVM use command:

lsblk
>> you see a structure like:
# lsblk

sda 8:0 0 10G 0 disk
??sda1 8:1 0 20G 0 part
??ubuntu--vg-ubuntu--lv 253:0 0 1999G 0 lvm /
sr0 11:0 1 2024M 0 rom
or
(3-1):
lvscan
ACTIVE '/dev/ubuntu-vg/ubnutu-lv' [<..GB] inherit
[if it is not active run: lvchange -ay /dev/ubuntu-vg/ubnutu-lv ]
