In ext4 filesystm however, both busybox' du -k and coreutils' du -k reports a size of 84k which causes the test to fail. =>du-k-works FAIL: du-k-works + mkdir du.testdir + cd du.testdir + dd if=/dev/zero of=file1 bs=1k count=64 + dd if=/dev/zero of=file2 bs=1k count=16 ++ busybox du -k . ++ busybox du -k . + test 'x84 .' = 'x80 .' -o 'x84 .' = 'x88 .' 24213 1 rongqing.li 2012-08-20 08:29:20 +0000 https://github.com/openembedded/oe-core/commit/a022fb6b69388f28f3130e71125b64e4c154d504 24606 2 alexandrux.palalau 2012-08-29 13:42:55 +0000 I have built the ext3 and ext4 images for the Qemux86 machine, core-image-minimal. Followed the steps presented below and got the following output: EXT4: file1 = 64k file2 = 16k busybox du -k . command returns 81 EXT3: file1 = 64k file2 = 16k busybox du -k . command returns 83 28832 3 kai.kang 2013-01-15 10:29:11 +0000 This is problem of the test case itself. It expect a directory occupies 0 or 8 kb which is the "block size" of file system. But when create a ext3/4 file system, mke2fs will use heuristics to determine the appropriate block size if '-b' is not provided. When the size of partition less than 512MB, the "block size" is 1024. That why the result of "busybox du -k ." is 81. We can 1 run mkfs.ext3/4 with "-b 4096" or "-b 8192", or 2 run this case on a partition which larger than 512M to make test case pass after the patch merged(and the patch is merged to busybox git repo). 29428 4 kai.kang 2013-02-01 02:00:28 +0000 Patch merged by busybox upstream, then backport it. 29517 5 liang.li2 2013-02-05 09:19:57 +0000 no error with git master branch commit 7e9cb437b1b720e656f4a33f73c07c5dc7356a2c.
