  • if don’t see free space listed, initiate a rescan of /dev/sda
  • #echo 1>/sys/class/block/sda/device/rescan
  • once done, re-run #cfdisk 

2. Select which partition to extending. Example - /dev/sda3 partition from the list and then select “Resize

3. ENTER and it will prompt to confirm the new size. Now /dev/sda3 partition with a new larger size.

4. LVM partition backing the  /dev/sda3 Physical Volume (PV) has been extended. Then need to extend PV

  • #pvresize /dev/sda3 -> 
  • #pvdisplay - to check the new size
  • #vgdisplay - check the Volume Group (VG) free space
  • #lvdisplay - check the size of our upstream Logical Volume (LV)
  • #lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv
  • #df -h - check current size of the file system
  • #resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv 
  • (centos) #xfs_growfs /dev/mapper/xxxx/xxxx
