once upon a time we randomly needed to add two new separate lvm logical
volumes to a server

1. verify which devices we will work with

   .. container::
      :name: cb1

      ::

         sudo disk -l

   We need to create physical volumes on both of these buggers:

   -  /dev/sdb
   -  /dev/sdc

2. create a physical volume on the 20G and 400G LUNs

   .. container::
      :name: cb2

      ::

         sudo lvm pvcreate /dev/sdb
         sudo lvm pvcreate /dev/sdc

3. create a volume group on the 20G and 400G physical volumes

   .. container::
      :name: cb3

      ::

         sudo lvm vgcreate vg1 /dev/sdb
         sudo lvm vgcreate vg2 /dev/sdc

4. create a logical volume on the new volume groups

   .. container::
      :name: cb4

      ::

         sudo lvm lvcreate vg1 -l 100%VG --name app
         sudo lvm lvcreate vg2 -l 100%VG --name data

5. format each logical volume with ext4 filesystem

   .. container::
      :name: cb5

      ::

         sudo mkfs --type=ext4 /dev/mapper/vg1-app
         sudo mkfs --type=ext4 /dev/mapper/vg2-data

6. create mount points

   .. container::
      :name: cb6

      ::

         sudo mkdir /app
         sudo mkdir /data

7. configure mount points in /etc/fstab

   .. container::
      :name: cb7

      ::

         /dev/mapper/vg1-app /app               ext4    errors=remount-ro 0       1
         /dev/mapper/vg2-data /data             ext4    errors=remount-ro 0       1

8. verify fstab

   .. container::
      :name: cb8

      ::

         sudo mount -a

9. verify new filesystems

   .. container::
      :name: cb9

      ::

         df -hal
