Sometimes while running a mix of sequential and random I/O's the generated sequential offset is outside the I/O region. This usually happens if the previous I/O is the last block in the region which results in this sequential I/O offset to be just outside the region. This results in fio finishing without doing the specified amount of I/O's. With this fix fio now generates a random offset within the region. Added a test case for the same (test_id: 28) As I see there is a pending patch with test_id: 27 so I decided to skip it to avoid conflict. This now fixes the issue: https://github.com/axboe/fio/issues/1486 Ankit Kumar (2): io_u: fix offset generation for mix of random and sequential workload test: add test for mix random and sequential workload io_u.c | 5 ++++- t/jobs/t0028-post.fio | 27 +++++++++++++++++++++++++++ t/jobs/t0028-pre.fio | 21 +++++++++++++++++++++ t/run-fio-tests.py | 34 ++++++++++++++++++++++++++++++++++ 4 files changed, 86 insertions(+), 1 deletion(-) create mode 100644 t/jobs/t0028-post.fio create mode 100644 t/jobs/t0028-pre.fio -- 2.17.1
