Check_snmp_storage.pl gives me a use of 123% about manubulon-snmp

You might want to look into the code regions where this is calculated. I would believe that there's an overflow somewhere.

I think the issue is with this part:

if (version->parse(Net::SNMP->VERSION) >= 4) {
    foreach my $key (sort keys %$result) {

        # Fix for filesystems larger 2 TB. More than 2 TB will cause an error because
        # as defined in the RFC hrStorageSize is a 32 bit integer. So filesystems
        # larger 2 TB report a negative value because the first bit will be interpreted
        # as an algebraic sign. (0 = +, all others will be -). You simply have to add
        # 2 to the power of 32 (4294967296) and it is fixed.
        # Martin Fuerstenau, Oce Printing Systems, 25th Sept 2012
        if ($$result{$key} < 0) {
            $$result{$key} = $$result{$key} + 4294967296;
        }
        verb("$key  x $$result{$key}");
    }
}

It looks like there is an overflow. If I'm correct the max volume size with int32 is 4TB. But when I change it to the max value of int64 "9223372036854775807" it still gets an overflow. Maybe perl needs to have the ability for int64?
Maybe that helps you?
