[SOLVED] Why is system taking over 60GB on Chromebook Edition

Community Support Question
1

I just got Chromebook Edition. After playing with it for a while, I noticed that the Chrome OS system takes 60.7 GB on the hard drive.

I went into developer mode and found an interesting output of lsblk that I don’t understand:

lsblk
lsblk1760×1402 381 KB

I thought that maybe developer mode might have to do something with it so I tried powerwash and then network recovery. It is supposed to repartition the hard drive and fix any issues. But I still get the same result.

Why the system is taking 60 GB out of the box? Isn’t it supposed to be around 16GB?

What’s the output of df -lh ?

I also use du -d1 -hr | sort -h to drill down and find what individual directories are taking up space.

lsblk shows you the size of “devices” and not how much space they take.

Based on your screenshot, Chrome OS take ~8GiB on your device. The first partition (nvme0n1p1) is actually the user data partition. This link should give you an overview of Chrome OS’ partitions design.

Within the user data partition, it seems that they uses LVM+dm-crypt to divide and encrypt the home area of individual users, evident by this (potentially out-of-date) documentation: ChromiumOS Platform - Filesystem layout
