LVM supports mirroring or raid1.
So to create a raid1 you would do something like "lvcreate -n raidvol
-L 1T --mirrors 1 /dev/bigvg"
You can add a mirror to an existing logical volume using lvconvert with
something like "lvconvert --mirrors +1 bigvg/unmirroredlv"
But other than simple mirroring you will need mdadm.

I have a Debian Buster box and there is no such command chvg. Correct
me if I am wrong....

LVM allows creating/converting striped/mirrored LVs without any
dowtime and it's using the md module.
