== Investigation 2: How can a PV be added to an existing VG? ==
'''Add an additional 2 GB virtual disk to your ''<u> fedora1</u>'' system, and use it as an additional physical volume :''' # Start <code>virt-manager</code>. # Shutdown ''fedora1'' if it is running. # Open the console window for ''fedora1''. # Select the menu option View>Details. # Click ''Add Hardware'' button at the bottom left-hand corner. # In the ''Adding new virtual hardware'' window that appears, select a Hardware Type of ''"storage"'' and click ''"Forward"''. # Make certain option "Managed or other existing storage" is selected. Click on the ''Browse'' button, then click on ''New Volume''. # Give the new virtual disk file a name of <code>fedora1b</code>, a format of ''raw'', with a ''Max Capacity'' and ''Allocation'' of 2000 MB. Click ''Finish''. # Select the new virtual disk file ''fedora1b.img'' and click ''Choose Volume''. # Select a device type of ''Virtio Disk''.# Finish creating the new virtual disk by clicking ''Forward'' and then ''Finish''. # Boot the system. You should now have both <code>/dev/vda</code> and <code>/dev/vdb</code>.
# Record the size of the volume group and the amount of free space (Hint: use a command that you learned in a previous lab).
Partition /dev/vdb with a single partition that fills the whole disk.
# Check the messages printed when <code>fdisk</code> exits -- you may need to reboot the system in order for the new partition table to take effect.
Run this command to format the physical volume: <code>pvcreate /dev/''vdb1'' </code># Add the new physical volume to the existing volume group : <code>vgextend ''nameOfVolumeGroup'' /dev/vdb1</code>
# Verify that the volume group is larger and has more free space.
