I installed Lubuntu without partitioning my hard drive. Now there is one partition for UEFI, and one partition for anything else on the hard drive, wherein there is a swap file half size of my RAM.

  1. I heard that it is important to separate /home and / into different partitions? For example, for protection of the data in /home, in case something goes wrong in /. Correct?

    If yes, can LVM help to separate the current /home and / on my disk for that purpose, given that /home and / are in the same partition right now?

  2. I also consider if it is worth to create a swap partition twice size as my RAM, for suspending Lubuntu purpose. Can LVM also help to create a swap partition on top of the partition?

I haven't used LVM before, so just want to know if LVM can help to solve the above two problems without the hassle of repartitioning the hard drive? Or do I have to repartition my hard drive into a partition for / and a partition for /home, most likely by reinstalling Lubuntu?

Thanks.
