Sometimes your store fills up the disk, but a simple
nix-store --gc
does not seem to clean all that much.
This usually means that you have some old collection roots that keep old versions of nixpkgs around.
Sometimes result
files created by an ad-hoc nix-build
bind a lot of resources, these can be found by running:
nix-store --gc --print-roots | egrep -v "^(/nix/var|/run/\w+-system|\{memory|/proc)"
# Darwin
nix-store --gc --print-roots | egrep -v "^(/nix/var|/run/\w+-system|\{libproc)"

There are multiple tools that can help with discovering gcroots and calculate the disk size:
