Another way to go would be to throw it in a 3D-array: 
use SuperSplit;

$array = supersplit('\s+','\n','\n----\n',\*DATA');

[download]
You'll have to handle $array->[$n][0] and ->[$n][1] differently, because they contain the date and text line. Considering the fact that you already know that every new ---- means it is another hour, you could discard the descriptive lines. 
my $str = '';
while( <DATA> )
  $str .= $_ unless m|^[/-]|;
}
$array = supersplit('\s+','\n','\n----\n',$str);

[download]
You could print the available space from the second filesystem for every hour like this: 
for (@$array){
  print $_->[1][3]."\n";  #remember indici start at zero
}

The supersplit module can be found here.

Hope this helps,
