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.
