OVA resizing

This is a non official procedure (which is working) which allows users to extend their VMware disk in order to be able to add more Volumes.

    1. OVA installation does not allow us to change disk size from default 100GB.

    2. Using CLI, we can also check the disk size:
      [root@apple:INOPERATIVE:Standalone] config # vgdisplay
       --- Volume group ---
       VG Name               vg-db-sda

       Total PE              25284
       Alloc PE / Size       19828 / 77.45 GB

      [root@edge:INOPERATIVE:] config # fdisk /dev/sda

      The number of cylinders for this disk is set to 13054.
      There is nothing wrong with that, but this is larger than 1024,
      and could in certain setups cause problems with:
      1) software that runs at boot time (e.g., old versions of LILO)
      2) booting and partitioning software from other OSs
        (e.g., DOS FDISK, OS/2 FDISK)

      Command (m for help): p

    3. Increase the hard disk size of the virtual machine. and then reboot the virtual machine. (in this example, we used 300GB)

    4. Once it is rebooted, run fdisk command to add a new partition: primary, partition 4. Then accept the default values. (Last cylinder size is differed how much size you assigned to the virtual machine)
      [root@apple:INOPERATIVE:Standalone] config # fdisk /dev/sda

      The number of cylinders for this disk is set to 39162.

      Command (m for help): m
      Command action

      Command (m for help): n
      Command action

      Last cylinder or +size or +sizeM or +sizeK (13053-39162, default 39162):
      Using default value 39162

    5. Now, using p command to show the new partition table. Make sure the added partition type, and change it to "Linux LVM"
      Command (m for help): p

    7. Now, run w command to save the new partition table. Then reboot the box for the changes to take place.
      Command (m for help): w
      The partition table has been altered!

      Calling ioctl() to re-read partition table.

      WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
      The kernel still uses the old table.
      The new table will be used at the next reboot.
      Syncing disks.
      [root@apple:Active:Standalone] config # reboot

    8. Once unit is rebooted, create a new physical volume using pvcreate command with key "-M1" extension, since fdisk create -M2 by default and need to have the same metadatatype.
      [root@apple:Active:Standalone] config # pvcreate /dev/sda4 -M1
       Physical volume "/dev/sda4" successfully created

    9. Makes sure the VG name and then add the new pv to volume group so that we can increase the disk size by vgextend.
      [root@apple:Active:Standalone] config # vgdisplay
