I noticed that Linux server distros are using LVM as default. What is so good about LVM, and when should I use it? Is there a GUI for managing LVM volumes like GParted, or is it just through the terminal? How is it different from RAID in using multiple drives for one volume?
Just so you know: btrfs can do that too Takes a while to evacuate a device and the tools are not great at reporting progress, but it does work.
