I'm not sure I understand the Q correctly, but,
If your VG includes the whole 27GB array, and contains 512 PPs at
32MB size, then you'll only see 16.5GB. To see the remaining 9GB
will need the PP size to change to 64MB. This cannot be done without
removing and recreating the VG.
If the VG contains more than 512 PPs (ie some of the array is not
allocated), then just increase the MAX LP'S value and increase the
LV/FS to suit.
I think you have the problem of allocating the whole VG to a filesystem
which is a lot smaller than you expected? Sorry if I misunderstand.
