    Windows agent reporting wrong disk usage

    Hello everybody,

    we have an issue where the zabbix agent which is installed on every windows host is reporting an incorrect disk usage of our cluster storage.
    Our zabbix server shows an usage of 27.5TB as shown here: Click image for larger version Name: dataurl280047.png Views: 353 Size: 9.2 KB ID: 465930

    While if I go directly to the NAS it shows that only around 20TB are in use:​

    While compression is active, it is not nearly enough to account for 7TB of data:

    Does anyone have a clou if what could be my issue here? Our Veeam Backup isnt reporting that the backup repository is almost full so it seems to me that just the zabbix agent is getting some weird numbers.
    Could this maybe just be an incompability with clusterstorage in general? Just to be clear, the values are the same with every of our three host machines.

    Thanks in advance!

      What other ways (graphical, cmd, PowerShell) do you have in Windows that you can use to get the disk usage? What are they reporting?

          Thanks for the hint, Markku! Since its shown as a folder in the explorer I didnt realize that I can actually see the capacity of the mounted drive when looking into its properties. Rookie mistake on my side.
          Of course it also shows the wrong size and therefore its not an issue with zabbix itself. I will look further into it and know where to look now.
          Thanks a bunch! Have a great day!

          Bumping this since it has been a month. Seems like I am the only one with this error.
