# DESCRIPTION:
|
|
# Verify mixed Direct I/O and buffered I/O. A workload of random
|
|
# but correctly aligned direct read/writes is mixed with a
|
|
# concurrent workload of entirely unaligned buffered read/writes.
|
|
#
|
|
# STRATEGY:
|
|
# 1. Create an empty file.
|
|
# 2. Start a background fio randomly issuing direct read/writes.
|
|
# 3. Start a background fio randomly issuing buffered read/writes.
