1. Check disk status: fdisk -l

2. Partitioning disk sdb:

Command: fdisk /dev/sdb

If you don't know what to do with fdisk, type m to help. The most common is n (new) d (delete) p (print) q (exit) t (modify system identifier) w (write and exit)

Create a new partition:

Enter p to print existing partitions (no partitions yet)

Enter n New partition

Enter p to create the main partition (p is after n, not print)

Enter 1 to create the first primary partition

Enter p to print the partition and find that a partition/dev/sdb1 has been created, but this partition is in Linux format

Change system identifier:

Enter t to change the properties of partition 1

Type L to see if there is a command corresponding to an attribute

Enter 8e to change partition 1 to Linux LVM format

Enter p to print the partition and find that the partition/dev/sdb1 is in Linux LVM format

3. Create PV:

Scanning system PV: pvscan

Create PV: pvcreate /dev/sdb1

View PV: pvdisplay

4. Create VG:

Scan system VG: vgscan

Create VG: vgcreate vg_test /dev/sdb1

View VG: vgdisplay

5. Create LV:

Scan system LV: lvscan

Create LV: lvcreate -l 1274 -n lv_test vg_test (1274 is the number of PEs in VG)

View LV: lvdisplay

6. Format the LV you just created

Command: mkfs -t ext4 /dev/vg_test/lv_test

7. Create directory and mount

Create directory: mkdir /test

Mount: mount /dev/vg_test/lv_test /test

View: df -h

8. There is also a final step, setting the boot mount.

Write/dev/mapper/vg_test-lv_test /test ext4 defaults 1 2 to/etc/fstab

So far, it's done.
