Fix for correct volume disk usage reporting

For anybody else who has a problem with the correct volume usage reporting, open the script and replace the line 317:

storageID[$i]=$(echo “$syno_diskspace” | grep “= “?/${storageName[$i]}$”?” | cut -d “=” -f1 | rev | cut -d “.” -f1 | rev)

with this:

storageID[$i]=$(echo “$syno_diskspace” | grep “= “/${storageName[$i]}”” | cut -d “=” -f1 | rev | cut -d “.” -f1 | rev)

and you should now get the correct volume usage (in percent) and the correct return state (depending on your -w and -c parameters).
