Hi Team, 

I am using RHEL v8.10 and I have  written ansible playbook to partition disk /dev/sda3  created, logical volume vg-system-home  and vg-system-var which i wanted to extend to 100G and 20G  but since this two are mounted already . 

 Either I am unmount them it gives resource busy or trying to extend the disk or remove this native volume manager and add the new volume home and mount on the /etc/fstab is not working . I  appreciate your immediate help or guidance to fix this issue.
