Current write size to the file "foobar" is too small to run readahead before the replacing on seed device. So, increase the write size to reproduce the issue. Following patch fixes it: "btrfs: start readahead also in seed devices" Signed-off-by: Naohiro Aota --- tests/btrfs/163 | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tests/btrfs/163 b/tests/btrfs/163 index 8c93e83b970a..24c725afb6b9 100755 --- a/tests/btrfs/163 +++ b/tests/btrfs/163 @@ -50,7 +50,7 @@ create_seed() { _mkfs_dev $dev_seed run_check _mount $dev_seed $SCRATCH_MNT - $XFS_IO_PROG -f -d -c "pwrite -S 0xab 0 256K" $SCRATCH_MNT/foobar >\ + $XFS_IO_PROG -f -d -c "pwrite -S 0xab 0 4M" $SCRATCH_MNT/foobar >\ /dev/null echo -- gloden -- od -x $SCRATCH_MNT/foobar
