Error "There is not enough space on X to copy"

[GijsKruize]

Dear Comunity,

I have just installed TrueNas on a Proxmox instance and i get an error only on windows machines stating that "there is not enough space to copy files", but there is anoter 9.5 or so TiB available as you can see in the code snippet below. I have looked all over the internet but i could not find a solution to this.

Now the weir thing is that it only gives this error on my windows 11 VM (which copied 200 GB's of files just before i started getting the error), i tried copying something over from my macbook pro and it works completely fine! I have included some screenshots and specs below,

Can someone please help me out?

Kind Regards Gijs
