Theory

PV (Physical Volume) - these can be partitions or entire “unpartitioned” disks

VG (Volume Group) - we combine physical volumes (PV) into a group, create a single disk, which we will further partition as we want

LV (Logical Volume) - logical partitions, the actual partition of our new “single disk” aka Volume Group, which we then format and use as a regular partition, a regular hard drive.

Work sequence

It is best to contact the Pallas's manual by command. Help's are poor and designed to help people who already know

# if you use whole disk drive, clear first sector of disk. For more information: man pvcreate
dd if=/dev/zero of=/dev/sdz bs=512 count=1

# Create PV
pvcreate /dev/sdb

# Create VG "data"
vgcreate data /dev/sdz

# Create Logical Volume
lvcreate -n data0 -l 100%VG data

mkfs.ext4 /dev/data/data0
