can anyone please explain how UnRAID formulates the total HDD space in an array?

when using

df -h

It will produce a nice even number, just not the same one that is reported by UnRAID.   In addition,  I use a grafana dashboard that has a total hard drive space panel and it also reports that same total space that is in agreement with UnRAID's total.   It is pulled from /mnt/user0

 

I am just curious how the hard drive capacity on the disk is reported in UnRAID when almost, if not every, other utility knocks off just over 7% of the total hard drive space.   

Google TiB vs TB

Is there a command that will display the same array space that unraid reports from the cli?

df -H

 

-H, --si              print sizes in powers of 1000 (e.g., 1.1G)

 

I didnt know there was a difference between -h and -H

 

That did the trick.  Thank you!
