Volume group has been expanded with 'vgextend'. Physical volume was created with 'pvcreate'. This field was made available with 'fdisk'. In this article, the size of the existing vmdk file has been increased by 10GB for the disk increase process in virtual Linux systems.

Increasing Logical Volume (Increasing LVM Disk Size) Make the new disk space available with the 'fdisk' tool.Ĭhanges will remain in memory only, until you decide to write them.īe careful before using the write command. Scan the scsi buses again so that the disk space you added can be detected by the system. You can increase the disk by deleting this clone, or if you do not want to delete the clone, turn off your virtual machine, do the disk increase and restart it.ĭetection of Added Disk Space by the System (The disk space, which was 20GB in the current system, was increased to 30GB.) If you cannot increase this area, it may be because your virtual machine is a clon. Select the hard disk in the settings section of your virtual machine and increase the 'Provisioned Size' section. df -hįilesystem Size Used Avail Use% Mounted on If you want to do the disk expansion for / (root directory), continue the process in the same way and use '/ dev / mapper / vg_system-root' instead of '/ dev / mapper / vg_data-data'. In this article, the size of '/ dev / mapper / vg_data-data' will be increased.

Specify the file system whose size you want to increase. Disk size expansion will be performed online on a virtual linux-based system installed on VMware ESXI. This article will share practical information about LVM rather than theoretical information. LVM (Logical Volume Manager) is a logical volume manager prepared for Linux based operating systems.
