[SOLVED] partition gparted clonezilla

[malesef]

I have succesfully cloned my server with clonezilla in -k1 mode to migrate bigger harddrive.
after this process I realize ,the part which is /dev/mapper/VG0-var that I need is still same size.
I have Gparted installed in my CentOS.
I need to resize /dev/mapper/VG0-var
but I cant see this partition in /dev/mapper/VG0-var in gparted.
I can only see sda,sdb and LVM
LVM is the biggest partition and I guess /dev/mapper/VG0-var inside of LVM.
any ideas how to resize dev/mapper/VG0-var more than welcome.
Thanks in advance

Thanks to all guys, Specially user "baumgart"

Gparted is a good partition program but it did not work my case. Since I had to deal with LVM file system

by guidance of 'baumgart' the lifesaver, I managed resizing /dev/VG0/var in 3 steps.

1-pvresize --setphysicalvolumesize 700G /dev/sda1 (resize sda1 to 700Gigabytes)

2-lvextend -L +500G /dev/VG0/var (add 500Gigabytes top on existing)

3-resize2fs /dev/VG0/var

and success

this is done after clonezilla expert mode -k1 is applied. Thanks to all
