I think command-line is the key word here. It is not so hard on Ubuntu in the GUI. But for example if you installed Red Hat CLI-only version, it's probably so h

  The thing is, if you're a desktop user, you generally use gparted. If you're not using a GUI, you're already a sysadmin in most cases. Systems like Raspberry Pi make these things easier, too. They both have docs, or you can do on your system with gparted already. Also, as I aforementioned, none of the CLI tools eat your data unless you force them to. Lastly, all the tools accept KB, MB, etc. as prefixes/suffixes. So, I rarely make back of the napkin math for these things, if ever. > But for example if you installed Red Hat CLI-only version, it's probably so hard you'll give up and just ask Red Hat support to look at your logs and send you the commands to run. Actually it's not hard. You only need to know that you have your filesystems in a LVM (Logical Volume Manager) container. Unless you're not changing the size of the LVM volume, it's the same thing, only the device name changes. If you're adding disks, you need to first increase the LVM size to span the other disk, and add or resize your partiton there. It's not intentionally hard, you meet with a layer you generally don't see everyday. Even if you boot a LVM containing system from a live distro, say GRML, you only need to "activate" the LVM container with a single LVM command, and it's the same thing after that point. It's a matter of thinking in layers.
