Does RAID support LVM?

LVM supports RAID levels 0, 1, 4, 5, 6, and 10. An LVM RAID volume has the following characteristics: RAID logical volumes created and managed by LVM leverage the Multiple Devices (MD) kernel drivers. You can temporarily split RAID1 images from the array and merge them back into the array later.

Should I use LVM when installing Ubuntu?

If you are using Ubuntu on a laptop with only one internal hard drive and you don’t need extended features like live snapshots, then you may not need LVM.

An administrator thinks of LVM as total combined storage space. Three hard disk drives are combined into one volume group that is then carved into two logical volumes.
