I have a small problem with my home partition. The size of the partition (ext4) is ~895GiB. I’m using ~77GiB of the partition but still the Dolphin shows me that I have 773 GiB free (so according to my calculations I’m missing ~45GiB).
I’ve looked everywhere but I don’t understand where did the missing space go.
I’ve heard of dodgy things happening if you drop much below 5%. But then, that might depend on absolute size too - and I don’t think your system would suddenly blow up (it might just run really slowly, for example…)
I would think you could get some fragmentation issues in an ext3 system if they let you use all the space on the drive. Ext3 is pretty good at avoiding that problem, but if they let you use every bit of the hard drive up you likely could start to see problems with the system, since it could never find an empty spot to place your files, and there couldn’t be room to allow them to grow in a contiguous space
