For Centos-08 Its not working. Can you Please help to make it work.

1. When it get rebooted, the fsresize service is not running
2. When the second time expanding the disk using this script, it'll give wrong output of disk expanded. ie If we add 20 GB in nextime, the re-sized value is more than that.
 Plesse check and fix this
