Resize/Extend LVM2 logical volume from unallocated space on RHEL/Rocky

• 1 Backup your data before performing any of the following steps
  
• 2 Use gparted to add some more unallocated space to the logical volume group
  
• 3 gparted -> R-Click /dev/nvm0n2p6 (lvm2 pv) -> Resize/Move + set new size -> Resize
  
• 4 lvdisplay | grep "LV Path"
  
• 5 lvextend -rl +100%FREE /dev/rehl/root
  
• N There should be some unallocated space on disk in the first place to be able to perform Step 3. Do not use whole disk space when installing OS and keep some unallocated space so partitions can be extended later on demand.
