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?
Opensuse can do this. Well put btrfs on LVM that is. I found out with my tumbleweed installs that if i use disk encryption and no LVM i do not have the option to boot from btrfs snapshots. Also with LUKS you need to type in your password twice when booting if you dont use LVM.
