A rootfs typically has lots of small files, so the default counter with 1024 inodes for 16 megabytes partition size can be too restrictive and leads to e.g.
root@box:/ touch /etc/config/test touch: /etc/config/test: No space left on device the solution is to just double the amount of inodes during image creation, so a 16mb part has 2048 inodes. see also: http://lists.infradead.org/pipermail/lede-dev/2016-November/003977.html Signed-off-by: Bastian Bittorf <b...@npl.de> --- include/image.mk | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/include/image.mk b/include/image.mk index 8b183ab..e74a71d 100644 --- a/include/image.mk +++ b/include/image.mk @@ -239,11 +239,13 @@ define Image/mkfs/ubifs -o $@ -d $(call mkfs_target_dir,$(1)) endef +# doubles the default inode amount +INODES=$(shell echo $$(($(CONFIG_TARGET_ROOTFS_PARTSIZE)*64*2))) E2SIZE=$(shell echo $$(($(CONFIG_TARGET_ROOTFS_PARTSIZE)*1024*1024))) define Image/mkfs/ext4 $(STAGING_DIR_HOST)/bin/make_ext4fs \ - -l $(E2SIZE) -b $(CONFIG_TARGET_EXT4_BLOCKSIZE) \ + -l $(E2SIZE) -i $(INODES) -b $(CONFIG_TARGET_EXT4_BLOCKSIZE) \ $(if $(CONFIG_TARGET_EXT4_RESERVED_PCT),-m $(CONFIG_TARGET_EXT4_RESERVED_PCT)) \ $(if $(CONFIG_TARGET_EXT4_JOURNAL),,-J) \ $(if $(SOURCE_DATE_EPOCH),-T $(SOURCE_DATE_EPOCH)) \ -- 1.9.1 _______________________________________________ Lede-dev mailing list Lede-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/lede-dev
