LVM RAID uses both Device Mapper (DM) and Multiple Device (MD) drivers from the Linux kernel. DM is used to create and manage visible LVM devices, and MD is used to place data on physical devices. LVM creates hidden LVs (dm devices) layered between the visible LV and physical devices. LVs in the middle layers are called sub LVs.

Create a partition for software RAID on both disks, leave approx 100MB at end of disk: gdisk /dev/sda n #add new partition. 2 #partition number 2. 4096 #default next sector. +59GB #Partition size. fd00 #partition type. w #write changes and exit. Create RAID1 array. Build two device array:

The wording of the article - ie. "Make the RAIDs accessible to LVM by converting them into physical volumes " and "Next step is to create a volume group (VG) on the PVs " - suggests both RAIDs are to be 'made into' PVs, and both PVs are to be 'put into' the VG. Sure, the commands don't reflect this, but they don't exclude it either.

NAME. lvmraid — LVM RAID. DESCRIPTION. lvm(8) RAID is a way to create a Logical Volume (LV) that uses multiple physical devices to improve performance or tolerate device failures. In LVM, the physical devices are Physical Volumes (PVs) in a single Volume Group (VG). How LV data blocks are placed onto PVs is determined by the RAID level.
