Investigation 1: Adding a physical volume

1. Stop the VM "fedora1".
2. Dump the XML for the virtual machine 'fedora1' into a file: virsh dumpxml fedora1 >fedora1.xml
3. Examine the file to determine the structure.
4. Add another virtual disk. Use the filename /var/lib/libvirt/images/fedora1-1.img.
5. Create the tile /var/lib/libvirt/images/fedora1-1.img as an empty file with a size of 10G: dd if=/dev/zero of=/var/lib/libvirt/images/fedora1-1.img bs=1G count=10
6. Start the VM.
7. You should now have a new disk, /dev/vdb
8. Use fdisk to create a single primary partition that fills all of the new disk.
9. Use pvcreate to format the new partition as a physical volume: pvcreate /dev/vdb1
10. Use vgextend to add the new PV to your volume group: vgextend InsertNameOfYourVGhere /dev/vdb1
11. Use lvextend to extend the size of the root filesystem by 5G: lvextend InsertNameOfYourVGhere/InsertNameOfYourLVhere --size +5G -r
    • Note that the -r resizes the filesystem withing the LV and is critically important!
12. Confirm that the LV has been resized.
13. Record notes about this investigation in your lab book.
