Now because of parted required in Fedora 16, I had to actually learn and 
re-learn(expect) a few things and now this works:

#!/usr/bin/perl -w
#
use Expect;
use strict;

my $re1='(\\s+)';    # White Space 1
my $re2='(2)';    # Integer Number 1
my $re3='(\\s+)';    # White Space 2
my $re4='(\\d+)';    # Integer Number 2
my $re5='((?:[a-z][a-z]+))';    # Word 1

my $re=$re1.$re2.$re3.$re4.$re5;

my $start = "";
my $logfile = "/tmp/wowsers";
my $timeout = 2;

my $account_id = $ARGV[0] or die "Usage: growit.pl account_id\n";
my $drive = "/dev/mapper/${account_id}";
my $parted = new Expect;

system ("iscsiadm -m session -R\n");
system ("multipath -r\n");
system ("partprobe $drive\n");

$parted->spawn("parted $drive") or die "Cannot spawn parted: $!\n";
$parted->log_file($logfile);

$parted->expect($timeout,'(parted)') or die "No prompt from parted\n";
$parted->send("print\n");
$parted->expect(2,'(parted)') or $parted->send("Fix\n");
if ( $parted->before() =~ m/FIx/is )
     {
     $parted->send("Fix\n");
     $parted->expect($timeout,'(parted)') or die "Could nor FIX it\n";
     }
$parted->send("print\n");
if ( $parted->before() =~ m/$re/is )
     {
     $start=$4.$5;
     print "Start = $start\n";
     }
$parted->expect($timeout,'(parted)') or die "Where am I?\n";
$parted->send("rm 2\n");
$parted->expect($timeout,'(parted)') or die "Deleted??\n";
$parted->send("mkpart primary $start -1\n");
$parted->expect($timeout,'(parted)') or die "mkpart?\n";
$parted->send("quit\n");

system ("partprobe $drive\n");
system ("fsck -f -y ${drive}p2\n");
system ("/sbin/resize2fs -p ${drive}p2\n");
system ("fsck -f -y ${drive}p2\n");

Advice is still welcome!

Thanks
