From: Xiaoli Feng <xifeng@xxxxxxxxxx> For large block size, such as 64k, there're maybe leave more than 768k space when disk is full. I met one. When I test 64k for dax. It leaves about 800k space when disk is full. So change to jude the free block for >4k fs. --- tests/generic/275 | 13 ++++++++++--- 1 file changed, 10 insertions(+), 3 deletions(-) diff --git a/tests/generic/275 b/tests/generic/275 index 3a016037..2c5a807f 100755 --- a/tests/generic/275 +++ b/tests/generic/275 @@ -62,9 +62,16 @@ rm -f $SCRATCH_MNT/tmp1 sync echo "Post rm space:" >> $seqres.full $DF_PROG $SCRATCH_MNT >>$seqres.full 2>&1 -_freespace=`$DF_PROG -k $SCRATCH_MNT | tail -n 1 | awk '{print $5}'` -[ $_freespace -gt 1024 ] && _fail "could not sufficiently fill filesystem" - +bsize=$(_get_file_block_size $SCRATCH_MNT) +bsize=$((bsize / 1024)) +_freespace=`$DF_PROG -k $SCRATCH_MNT | tail -n 1 | awk '{print $5}'` +# When block size is >4k, use the free counts of block to judge +if [ "$bsize" -gt 4 ]; then + _freeblock=$((_freespace / bsize)) + [ "$_freeblock" -gt 256 ] && _fail "could not sufficiently fill filesystem" +else + [ "$_freespace" -gt 1024 ] && _fail "could not sufficiently fill filesystem" +fi # Try to write more than available space in chunks that will allow at least one # full write to succeed. dd if=/dev/zero of=$SCRATCH_MNT/tmp1 bs=128k count=8 >>$seqres.full 2>&1 -- 2.18.1
