Hi,

When building my Raspberry Pi3 image with Buildroot an error was reported:

"Could not allocate block in ext2 filesystem while writing file "aoe.ko"".

Please advise me how to solve this problem.

ere is the copy of the last couple of messages reported by Buildroot:

mkdir -p /home/ptomov/buildroot/output/target/etc
( \
	echo "NAME=Buildroot"; \
	echo "VERSION=2017.08-git-01093-gf307f84-dirty"; \
	echo "ID=buildroot"; \
	echo "VERSION_ID=2017.08-git"; \
	echo "PRETTY_NAME=\"Buildroot 2017.08-git\"" \
