Hello!

I found some script on other forum and rebuilt it.
It works
Code:
#!/bin/bash

DSIZE=`fdisk -l /dev/sda | grep "Disk /dev/sda" | cut -f 3 -d " " | awk -F "." {'print $1'}`
SWAPSIZE=4;
DATASIZE=$[$DSIZE-$SWAPSIZE];
echo "Disk size:               $DSIZE GB";
echo "Size for data partition: $DATASIZE GB";
echo "Size for swap partition: $SWAPSIZE GB";

partx

PARTX(8)						      System Manager's Manual							  PARTX(8)

NAME

       partx - telling the kernel about presence and numbering of on-disk partitions.

SYNOPSIS

       partx [-a|-d|-l] [--type TYPE] [--nr M-N] [partition] disk

DESCRIPTION

       Given  a  block	device	(  disk  ) and a partition table type , try to parse the partition table, and list the contents. Optionally add or
       remove partitions.

       This is not an fdisk - adding and removing partitions is not a change of the disk, but just telling the kernel about presence and numbering
       of on-disk partitions.

OPTIONS

       -a     add specified partitions or read disk and add all partitions

       -d     delete specified or all partitions

       -l     list partitions. Note that the all numbers are in 512-byte sectors.

       --type TYPE
	      Specify the partition type -- dos, bsd, solaris, unixware or gpt.

       --nr M-N
	      Specify the range of partitions (e.g --nr 2-4).

SEE ALSO

       addpart(8), delpart(8), fdisk(8), parted(8), partprobe(8)

AVAILABILITY

       The partx command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
