How to increase rhel-root space?

[rmunny]

In my RHEL 7.8 server, I have allocated 100GB for /root. I need more space because I need to install more software that will be available systemwide for all users. I am new to Linux and not very familiar with the system. My questions are:

1. If I want to increase my /rhel-root, what should I do?
2. If I can't increase the space, how can I change the download and software Installation location?
3. For case 2, is there anything else I need to do so my users have access to the installed software?

Thanks a lot for your time!

Try this:
# growpart /dev/sda 2
CHANGED: partition=2 start=2099200 old: size=1 end=2 new: size=3,end=4
Hope this helps.
