/ was overflows

[三輪晋( Miwa Susumu ) <miwarin%gmail.com@localhost>]

hi.

/ (root) was overflows.
How do I get to find out, consuming capacity?


question
========
I ran the sysbuild build. And it was in error.

/ was full for a long time. or impact of sysbuild. I do not know it.
As it, Where is  / overflowing? I should I examine how?
