====================
volume name
> .1.3.6.1.2.1.25.2.3.1.3.x  == volume name of drive x

> .1.3.6.1.2.1.25.2.3.1.4.x == block size  (byte) of drive x

> .1.3.6.1.2.1.25.2.3.1.5.x == total blocks of drive x

> .1.3.6.1.2.1.25.2.3.1.6.x == used blocks of drive x

bytes = blocksize*number of blocks.

I use this script.
it returns the used, and free space on a drive, with index number $disknbr

(you can modify it for your own purposes)
===================================
my @snmpoutput = `snmputil get localhost public
host.hrStorage.hrStorageTable.hrStorageEntry.hrStorageAllocationUnits.$diskn
br`;
my $blocksize = $snmpoutput[1];
chop $blocksize;
$blocksize =~ s/^.*Integer32[\t ]*(\d*).*$/$1/;

my @snmpoutput = `snmputil get localhost public
host.hrStorage.hrStorageTable.hrStorageEntry.hrStorageSize.$disknbr`;
my $totalblocks = $snmpoutput[1];
chop $totalblocks;
$totalblocks =~ s/^.*Integer32[\t ]*(\d*).*$/$1/;

my @snmpoutput = `snmputil get localhost public
host.hrStorage.hrStorageTable.hrStorageEntry.hrStorageUsed.$disknbr`;
my $usedblocks = $snmpoutput[1];
chop $usedblocks;
$usedblocks =~ s/^.*Integer32[\t ]*(\d*).*$/$1/;

$freeblocks=$totalblocks-$usedblocks;
print $usedblocks*$blocksize . "\n";
print $freeblocks*$blocksize . "\n";
print localtime();
print "\ndiskspace\n";
========================================
