Can you please tellme what version of snmp are you using on which os?
I'm using OpenIndiana 148 with snmp
snmpstatus -V
NET-SNMP version: 5.4.1
For use 64bit counters (dskTable), need net-snmp > 5.5

Thank you!

Disk size is right for me.

[root@nas ~]# df -h | grep Media
Media                          2.2T    1.2T    1.0T    55%    /mnt/Media
[root@nas ~]# zfs list -o space
NAME   AVAIL   USED  USEDSNAP  USEDDS  USEDREFRESERV  USEDCHILD
Media  1.01T  1.21T         0   1.21T              0      21.1M

$ php ./poller.php -m storage -h nas.stupalov.ru
<http://nas.stupalov.ru> | grep Media
Storage /mnt/Media, type: zfs, dev: Media: 55%

If something is not right for you, then the problem is snmpd on your
server.

    Thank you Mike for the update,

    it is more accurate indeed, but on larger filesystems is more wrong,
    eg before on a system occupied 92% from 25TB it would report
    148% and show some random size,
    now after the update is says 4% occupied

    zfs list  -o space | grep tank
    tank                1.17T  23.8T     3.77T   20.1T             
    0          0

    observium reports
    /tank         4%

    and that ever reversed is not the case

    is good  for filesystems under a certain size, maybe 2TB.

    Also, if possible, please add the filesystem quota in the graph,
    now is not there.

    Best!

        Please check the size (and occupancy) displayed with a new
        r3778.

        For a quick check, after the upgrade, run the command:
        php ./poller.php -m storage -h <device>

        The problem is that using 32bit counters.
