Noob Q - How do you find the disk used information?

[AustinPowers]

In my case, I have set up a ZFS FreeNAS with a 1TB drive for the purposed of experimentation.

But I am getting REALLY weird stats from the FreeNAS box - saying it has 3.1TB of free space on a 1TB drive - does not compute.......

Add up the SIZE column.

...I don't get it.....

Even if you add up the AVAILABLE column, you end up with 2.85TB for a 1TB drive - What the F ?!???!!

All I really want, is an indication of how much space is left on the 1TB drive, but I can't find it. Can anyone help me understand this? It is probably a ZFS thing, and I am only familiar with Windows and NTFS, but even though - most Linux or Unix systems will still have a way to tell you how much space is used, and what is left, for any specific drive... :(

Looking at your screenshot it is REALLY simple to see how much space is left:
570.1 GB

Not sure why you think you should be adding up the Available column

Where are you getting that from?

Even if I add up the USED column, it comes to 343.5GB, so 1000GB-343.5 = 656.5GB NOT 570.1GB, so I still don't understand where you got that figure from.

What's with the AVAILABLE and SIZE columns - I don't understand this, as they both add up to way more then the total available space on the disk - this is the bit that is really confusing me.

I added up the AVAILABLE column, as this is what it says is available, and I can tell just by looking at it, that this cannot be correct, as a simple glance at that column, says there is more space available, then there actually is on the drive that is installed.

I'm not really sure why you are adding up the available column. It obviously lists all those datasets on one volume
