I managed to work this out and am posting the solution to help anyone who has the same problem.

Basically, you need to:

  • boot into the BigIP MOS (Maintenance Operating System)
  • extend and resize the logical shared partition
  • reboot

The steps are as follows:

  • boot into the BigIP MOS (Maintenance Operating System)

    • boot into the BigIP as normal
    • use the 
      grub_open
      command the get the grub file to modify
    • edit the file, changing default to '1' instead of '0'
    • use the 
      grub_close
      command to save the modified file.
    • reboot. This time the VM should go into 'MOS' mode without mounting any of the file systems.

  • extend and resize the logical shared partition

    • use 
      lvscan
      to list the available partitions
    • use 
      lvextend
      to extend the partition in question (Reference: http://tldp.org/HOWTO/LVM-HOWTO/extendlv.html)
    • use 
      resize4fs
      to resize the enlarged partition.
    • reboot. The default is reset automatically and the VM reboots into normal mode.

Now you should see that the mount has been resized.

Hope it helps someone.

Cheers, Steve
