"Show apparent size" needed for WSL instance to Windows drive

[daniejstriata]

Hi,

I'm not sure why this is happening but when I run gdu -dn I get the following output:

  Device      Size      Used      Free Used% Mount point
/dev/sdc 251.0 GiB  13.7 GiB 237.3 GiB    5% /

when I am inside a mnt to the Windows drive from my WSL the following happens:
/mnt/d/Data/repo/security

$ gdu -n
    7.8 EiB /packages
    4.8 EiB /app1
  -463550477559806976 B /app2
  -3473665266239336448 B /audit_configs
  -3801883870989672960 B /server-fixes

to get the proper output I need to run it like this:

$ gdu -na
  106.9 MiB /packages
    1.0 GiB /app1
  333.1 KiB /app2
  215.4 KiB /audit_configs
  442.2 MiB /server-fixes

Is this expected behaviour? I'm not sure why the mnt is confusing the space from within WSL.

Interesting, I will need to install WSL to check this, so it will take me some time.

I've noticed that dust is doing the same thing on WSL drives. It must be the way the kernel presents the filesystem, what is "apparent size" actually?
