In next step i had to prepare or format that freespace with using this command : cfdisk /dev/sda Then i was able to see added space in ubuntu with command : fdisk -l Where # i had to replace with numbers for every host in scsi_host. After that i needed to rescan my ubuntu server with something like : echo "-" > /sys/class/scsi_host/host#/scan At first i needed to enlarge my disk size in vmware enviroment.

So, first of all, you have to run LVM with root password.I have the following problem. You must have root privilege to run any LVM command. Creating, Resizing and Removing LVM Components In this tutorial, you will learn different utilities of LVM, such as how to create or remove a new volume, how to find out the information about current volumes, how to resize existing volumes of the disk on Ubuntu and creating snapshot of a running system. The collection of all physical and logical volumes is called volume group. Each logical volume holds a file system which corresponds to a partition and a unique name is assigned for each logical volume. The block devices that are used to store logical volumes are called physical volumes. Three main components of LVM are physical volumes, logical volumes and volume groups. Volumes of the disk can be extended on the fly to provide more flexibility to the system based on requirements.Creation of software RAID partitions or standard partitions of a single disk.Creates striped logical volumes of the disks.Change the file system of any existing partition or remove any partition from the system quickly. Space of any partition can be resized or assigned to any low space partition at any time.Operate on the system without knowing the total space of any partition.Manage the space of multiple hard disks by creating logical volumes.Create, resize, move and delete partitions on the disks.LVM or Logical Volume Manager makes management of disk space on a Linux machine easier to manage.
