FIO is very flexible io generator, i would call it IO swiss knife.
Currently we have tonns of hardcoded application which reproduces
some predefined scenario. This approach has obvious dissadvantages
1) Lack of flexability: one written it is hard to modify it in future
2) Code base is large, many routines written again and again
At the same time add new fio based tast is just add simle INI file.
This greatly simplify code review. I do beleve that some day we will
replace most of hardcoded io binaries with fio.
One who is planning to run $FIO_PROG should first check that system
contains appropriate version which is able to handle jobfile
for example: _require_fio 286-job.fio

* [PATCH 2/6] xfstest: add configurable load factors

Most stress test has probable behaviour, the longer test run the
larger corner cases will be cover. It is reasonable to allow
user to provide some sort of system load factor.
This patch introduce two global variables
LOAD_FACTOR: Usually means factor number of running tasks
TIME_FACTOR: Usually means factor of run time, or number of operations
If not speficied both variables defined to 1, so original behaviour
preserved.
TODO: Change all stress tests to use this variables

Run DIO, fallocate and punch_hole threads on a common file in parallel.
If race exist old dio request may rewrite punched block after it was
allocated to another file, we will catch that by verifying blocks content.

Perform various regression tests for ext4defrag subsystem
Test1: Defragment file while other task does direct AIO
Test2: Perform defragmentation on file under buffered AIO
while third task does direct AIO to donor file
Test3: Two defrag tasks use common donor file.
Test4: Stress defragmentation. Several threads pefrorm
fragmentation at random position use inplace=1 will
allocate and free blocks inside defrag event improve
load pressure.
This test known to caught most known e4defrag bugs.

They probably need to be exparted variables set up through the
check script, not somthing sourced via common.config. i.e. something
like this in check where the environment is being set up:
export TIME_FACTOR=${TIME_FACTOR:=1}
export LOAD_FACTOR=${LOAD_FACTOR:=1}
Cheers,
Dave.

I'd much prefer a wrapper around fsstress than have to code this
into every test. Something like:
run_fstress()
{
args=""
while [ $# -gt 0 ]; do
case "$1" in
-n) args="$args $1 $(($2 * $TIME_FACTOR))"; shift ;;
-p) args="$args $1 $(($2 * $LOAD_FACTOR))"; shift ;;
*) args="$args $1" ;;
esac
shift
done
$FSSTRESS_PROG $args
}
And so all you need to do is something like:
$ sed -i 's/\$FSSTRESS_PROG/run_fsstress/' [0-9][0-9][0-9]
To convert all tests that use fsstress to do this.
You might also want to do this for the tests that run dirstress as
well, and create a "stress" group so that you can run just
the stress tests easily....
Cheers,
Dave.

Before this, please move all the other test setup stuff like the
_require directives before this. That way I don't have to scroll

It's not clear to me where the file names come from. I think it's
because the FIO job takes the name of the file if it's not specified
from the job name (i.e. [direct_aio]). If so, can you make that a
variable and comment to the effect that the filenames are derived from
the FIO job definition?

Once?

/me has to look up what kill -0 does, as 0 is not a valid signal
number.
The kill(1) man page doesn't document it, kill -l doesn't list 0
as a valid signal, and signal(7) doesn't document it either.
Wonderful!
Oh, there it is - in the syscall documentation (i.e. kill(2)):
"this can be used to check for the existence of a process ID"
Right, OK, now I understand the loop. :)

No need to unmount the SCRATCH_DEV on exit - that will happen if
necessary next time _require_scratch is called by a test....

No need to unmount before checking, the _check_scratch_fs function
does that for you and will leave unmount errors in the log if it
fails. i.e. the test will fail the check and the reason will be
obvious from the output...

Why the ENOSPC group? I don't see anything that exercises ENOSPC
behaviour in the test, and none of the comments indicate that it

Once?

/me has to look up what kill -0 does, as 0 is not a valid signal
number.
The kill(1) man page doesn't document it, kill -l doesn't list 0
as a valid signal, and signal(7) doesn't document it either.
Wonderful!
Oh, there it is - in the syscall documentation (i.e. kill(2)):
"this can be used to check for the existence of a process ID"
Right, OK, now I understand the loop. :)

No need to unmount the SCRATCH_DEV on exit - that will happen if
necessary next time _require_scratch is called by a test....

No need to unmount before checking, the _check_scratch_fs function
does that for you and will leave unmount errors in the log if it
fails. i.e. the test will fail the check and the reason will be
obvious from the output...

Why the ENOSPC group? I don't see anything that exercises ENOSPC
behaviour in the test, and none of the comments indicate that it

Please do these as 4 separate tests so that it is easy to
isolate/reproduce failures caused by a specific test that is being
run.
Same comments as previous two patches, as well.

Even though e4defrag is not used, it's probably still a good idea to
call _require_defrag to check for systems that have a recent enough
ext4 to run defrag on. e.g. a recent fio on an old distro might
result in fio saying "I understand this job file" but then not be
able to run defrag...
Cheers,
Dave.
