There are 3 steps to this. Create a partition Use fdisk to create your partitions. Use fdisk /dev/DISKID to do this. DISKS is generally something like sdb
fdisk /dev/sdb
Press "p" to print the partitions, there will be none on an empty disk
Press "n" to create a new partition
Create a primary partition on partition number 1 for a new disk. Accept defaults to use full disk for first and last cylinders.
Press "t" to change the type of the partition to 8e (Linux LVM)
Press "p" to double check the new parition and then press "w" to write the changes
Format partition
Create LVM disk pool
pvcreate /dev/sdb1 vgcreate vgpool /dev/sdb1 lvcreate -l 100%FREE -n lvstuff vgpool mkfs -t xfs /dev/vgpool/lvstuff mkdir /mnt/data mount -t xfs /dev/vgpool/lvstuff /mnt/data
Now check that the disk shows up and you can get to it
df -h cd /mnt/data/
You can use "pvdisplay" command to display the physical volumes now on the system
