- Resize vmware hdd size. - Create new partition using cfdisk: with fdisk error occur "no free sector available" $ sudo cfdisk /dev/sda new -> logical -> Size( in MB) : 89121.62 Type -> 8E Write -> yes Quit - Reboot server: $ sudo reboot - Assuming you created partition /dev/sda6, let's now create the physical volume in that partition: $ sudo pvcreate /dev/sda6 - Now let's extend the server's Volume Group to that physical volume. $sudo vgdisplay This will give you the info on your current Volume Group. Note down the entry next to "VG Name". That's your Volume Group name. $ sudo vgextend EnterVolumeGroupNameHere /dev/sda6  - Since we're (essentially) extending the main logical volume, let's get the name of that: $ lvdisplay and note down the entry next to "LV Name". This is your logical volume's name (e.g. /dev/srv/root), which you'll now extend to the newly added partition/physical vol...
