why does df -h / show way more disk space than I actually have on the drive?

[rbavery]

I installed wsl to my I drive which I confirmed by finding the ext vhd file.

It only has 512 GB but wsl shows this

rave@rave:~$ df -h /
Filesystem      Size  Used Avail Use% Mounted on
/dev/sdd       1007G 1013M  955G   1% /

this got me into an error where I tried to download more data than my drive supported. Is something misconfigured? How can I get wsl to accurately report drive space?

WSL 2 automatically resizes these VHD files to meet storage needs. You can try to use optimize-vhd command in Powershell which may reduce the size of a virtual hard disk file.

@Biswa96 I guess the issue is not how much space the VHD takes, but that the actual harddrive has 512GB and within WSL it shows that the disk has 955G. This seems not right.

@Biswa96 did you get answer?? I am also seeing exactly same. its showing 955 GB but i have only 500 GB in total.
