[Freshly formatted 8TB had 56GB used??]

I did a bit more research on reflinks. It looks like when it's formatted vis XFS, there's a command happening behind the scenes with reflink=1. I would imagine that there's someway to reformat my drives with reflink=0. I lookd into this feature, and I don't think I'll need it as it's useful for VMs and I'm not going to be dealing with that.

It's normal with recent xfs drives, it uses adicional space for new functions, like reflinking.

 

 

Is there any way to turn that off, or is it just how it is?

[Freshly formatted 8TB had 56GB used??]

I just set up a new UnRaid setup, formatted my drives, and Disk 1 has 80GB used (the 21GB docker image is there), and Disk 2 has 56GB used, even though when you navigate to it, there's nothing there. I've seen other forum posts here saying that a 4TB drive has a couple gigs reserved, perhaps put there pre-allocated for directory structures or something like that. But 56GB on an 8TB is outrageous! Is there any way to fix this?

 

Thanks in advance!
