Which is why he was saying it should be at least 920 GiB, not 999.
1TB ~= 954GiB
Exactly.
Where is all the extra space going ?
If /dev/sda1 is 512 MiB , /dev/sda2 is 1 GiB and the whole disk is 930 GiB then the remaining root partition should actually be at least 920 GiB right ?
Instead it's only 829 GiB, where is the ~100 GiB getting lost ?
