1. Challenge

   Create Physical Devices

   1. Get the names of our disks:

      fdisk -l
      

   2. Create the physical devices:

      pvcreate /dev/xvdg /dev/xvdf
      

2. Challenge

   Create a Volume Group

   Create a volume group on the physical devices we created in the previous task:

   vgcreate RHCSA /dev/xvdg /dev/xvdf
   

3. Challenge

   Create a Logical Volume

   Create the Logical Volume:

   lvcreate -n pinehead -L 3G RHCSA
   

   • -n denotes the name of the LV.
   • -L denotes the size of the LV.
   • RHCSA is the name of the volume group we're creating this LV in.
4. Challenge

   Format the LV as XFS and Mount It Persistently at `/mnt/lvol`

   1. Format the disk as XFS:

      mkfs.xfs /dev/mapper/RHCSA-pinehead
      

   2. Create a mount point:

      mkdir /mnt/lvol
      

   3. Get the UUID:

      blkid
      

   4. Copy the UUID, and edit /etc/fstab.

   5. Create a new line that looks like:

      UUID="THE-UUID-YOU-COPIED" /mnt/lvol xfs defaults 0 0
      

   6. Save and exit, and then run:

      mount -a
      

5. Challenge

   Grow the Mount Point by 200 MB

   1. To grow the LV, run:

      lvextend -L+200M /dev/RHCSA/pinehead
      

      To have the LVM tools automatically resize the filesystem, you could pass the -r or --resizefs flags.

   2. Another way to resize the filesystem is by running:

      xfs_growfs /mnt/lvol
