'size' denotes both the size of the region for IO, as well as the
amount of IO to transfer. Sometimes it's useful to be able to set
them separately instead. With this patch, you can do:

size=100G
io_limit=10G

and have fio do 10G of IO between 0..100G of the address space.

b5f4d8baefc6eb3e13235b7d9042b7ffecdb23dd 20-Mar-2014 Jens Axboe <axboe@fb.com> Unlink after file close

Sébastien reports:

I'm having an issue on windows : unlink=1 is not working (temp file are
still there) and it's working fine on unix

Looking at the code in close_and_free_files function :

[...]
if (td->o.unlink && f->filetype == FIO_TYPE_FILE) {
dprint(FD_FILE, "free unlink %s\n", f->file_name);
unlink(f->file_name);
}
[...]

Unlink() fails because the file is still open : On Solaris, truss shows
the following :

[...]
write(3, "\0\0\0\0\0 ;80\0\0\0\0\0".., 32768) = 32768
unlink("/data/fio/random_rw.0.0") = 0
close(3) = 0
[...]

So unlink is called first.

I would put this unlinking phase AFTER the remove_file_hash call.

bcbfeefa7bce8383cf85fe59ced91f54821dfbd2 20-Feb-2014 Christian Ehrhardt <ehrhardt@linux.vnet.ibm.com> fio: add multi directory support

This patch adds support for ':' seperated multiple directories at the
directory config statement in order to achieve an automatic distribution
of job clones (numjob) across directories.

That way people can distribute a load across these directories (usually
mount points of disks) automatically - changing numjob will be
sufficient to get all job clones evenly (optimal if dirs % numjobs = 0,
otherwise as good as possible) distributed at all times.

To avoid confused users old config Files will behave like they always
did, old fio binaries using new config files won't abort but just use
the first specified dir. If one specifies an explcit (non generated)
filename the distribution to many directories is also deactivated.

It also fixes an issue of events seeming out of order like when running
with --debug=file seeing the "..." message meaning "I created the
clones" prior to the last clone activities. Now the clones are called
with index N-1 .. 1, zero being the base thread as before.

The way fio parses options, we need to have the file locking
defined before we start adding files. Normally we can handle
this with option priorities, but that doesn't work across
job section boundaries. So catch this case and error out,
otherwise fio will segfault when it attempts to unlock files
at the end of a job.

O_ATOMIC makes writes atomic, meaning that they are fully stable
on media (in the event of a power cut) when acknowledged by the
device and OS.

This only truly works on Linux with the pending patches to
add O_ATOMIC.

Updated by Jens to:

- Add man page and HOWTO description of the option
- Make O_ATOMIC imply O_DIRECT, so that it actually works if you
don't set O_DIRECT manually.
- Add the option to the conversion list so it works for
client/server.
- Error handling so that if atomic=1 is set and the OS does not
support it, error out instead of just pretending it works.

57e54e087e051186d18cdedad20a2460463d4d30 20-Sep-2013 Juan Casse <jcasse@chromium.org> Fixes bug: stale LAST_POS(f) is not being reset

Problem:
When running fio with ioengine=sync, LAST_POS(f) state is not
reset after the file is closed. This causes workloads with
readwrite=randread and loops > 1 to fail verification if the
state of LAST_POS(f) at the beginning of the next loop is the
same as the io_u->offset. If that is the case, lseek in not
invoked, but the file position is at 0 and not at io_u->offset.

Proposed Solution:
Other ioengines, such as binject and fusion-aw, set f->engine_data
to 0 when closing the file. The sync ioengin uses f->engine_data to
store the LAST_POS(f) state. The proposed solution is to set
f->engine_data = 0 when closing a file in generic_close_file().

3e10fb832645e3ab3ef006f589f0459dc567cb53 09-Aug-2013 Jens Axboe <axboe@kernel.dk> verify: fix problem with hole punching on newer Linux kernels

Jeff Moyer writes:

Our QE team noticed fio failures on recent kernels. I simplified the
job file to the following:

[global]
name=fio-mmap
rw=write
bs=4K
direct=1
end_fsync=1
verify=crc32

[file3]
size=100M
ioengine=mmap
mem=malloc
direct=1

After fio completes (and returns verify errors), the file is completely
full of zeroes.

Here is what the verify logic is doing:

static void do_verify(struct thread_data *td, uint64_t verify_bytes)
{
...
/*
* sync io first and invalidate cache, to make sure we really
* read from disk.
*/
for_each_file(td, f, i) {
if (!fio_file_open(f))
continue;
if (fio_io_sync(td, f))
break;
if (file_invalidate_cache(td, f)) <--------
break;
}

That invalidate cache call looks like so:

static int __file_invalidate_cache(struct thread_data *td, struct fio_file *f,
unsigned long long off,
unsigned long long len)
{
...
/*
* FIXME: add blockdev flushing too
*/
if (f->mmap_ptr) {
ret = posix_madvise(f->mmap_ptr, f->mmap_sz, POSIX_MADV_DONTNEED);
(void) posix_madvise(f->mmap_ptr, f->mmap_sz, FIO_MADV_FREE); <-------

FIO_MADV_FREE can be defined as MADV_REMOVE, which will actually punch a
hole in the file (a hole the size of the entire file, btw). Of course,
unallocated blocks are returned as zeroes by the file system, so that
explains that!

---

For now, only do the MADV_FREE on non-files to avoid punching holes.
Further investigation is needed on the blockdev side, but at least
this should cure the immediate problem.

d474cbc9ba33448848b50cc697622a402e91e33e 08-Mar-2013 Alex Pyrgiotis <apyrgio@grnet.gr> Improve LFSR implementation

Changes:

1. Use Galois LFSR instead of Fibonacci LFSR.
2. Use XNOR gates instead of XOR gates.
3. Add tap sizes for LFSRs ranging from 3-bits to 15-bits.
4. Add spin parameter.

Rationale:

1. Fibonacci LFSRs have the following drawbacks:

a. Their next state can not be computed in one cycle, since the input
bit must be propagated serially through the XOR gates. Galois
LFSRs however, can be computed instantly with XOR-masks.

b. Their state changes cannot be considered "irregular", even by I/O
standards. Actually, if the current state of an n-bit LFSR is x,
then the next will either be (x >> 1) or (2^n + (x >> 1)). Galois
LFSRs have instead their XOR gates interleaved with their bits,
which means that the inner bits are changed as well, besides of
the shifting. If the number of taps is z, this means that the
different outcomes are 2^(z + 1).

2. An LFSR with XOR gates has the all-zeroes state as illegal. Since
zero is valid for most I/O operations, it would be more intuitive to
use XNOR gates, that have as the all-ones state as illegal.

3. Allow smaller I/O benchmarks to use LFSRs.

4. The spin parameter follows the same rationale as in 1b. To make the
LFSR outcome "appear" less predictable, we can spin internally the
LFSR state and produce the i-th number. To understand the spin
parameter, consider the following state sequence of a 3-bit LFSR:

0, 2, 3, 5, 6, 1, 4
Same LFSR, spin value 2: 0, 3, 6, 4, 2, 5, 1
But what is the benefit from using spin? Well, the benefits are
two-fold:

a. For the same I/O size, we can create a different I/O sequences.

b. Following the rationale of 1b, we can have more variable outcomes.
If the spin value is "i" and the taps are "z", the number of
different outcomes become i * 2^(z + 1).

Three separate little issues:

- Don't round up the number of blocks needed. That means we end
up with potential partial blocks, which we can never do IO to.

- Fix an axmap bug where we only check against the specific bit
in the mask, but we really want to check for "this bit or any
higher bit". This makes axmap_next_free() behave more like it
should, instead of failing way too often.

- For the almost-full case, we can return a next available bit
that is just outside the allowed range. Punt to first-free for
that case.

It is valid to use size=foo, where foo is larger than the size
of the file or device. For that case, we don't want offsets
larger than the size of the file. So use the minimum of the
real or given size.

e6c4d732fc99070091367d0ce41fe2cf1ddd1dc9 12-Dec-2012 Jens Axboe <axboe@kernel.dk> file hash: don't close file fd on lookup/add race

On Linux, udev often has a rule that triggers blkid to read data off
the device, if the device has been opened for writing. This triggers
when the device is closed.

Fio has an internal file hash for lookup of files. When threads start,
it can happen that one thread does a hash lookup without finding the
file, but when it has opened the file and attempts to insert it into
the hash, another thread has already completed that operation. When
that race happens, fio closes the file handle and does the lookup
again. That then triggers blkid to read pages off the device. As data
in the cache is invalidated on open of the device, we know have page
cache entries for the device again.

This is a problem for unbuffered workloads, where the existance of
page cache pages slows it down due to having to check for invalidation.
The user observed problem is that fio exhibits bi-modal performance
results, depending on whether the file hash race was hit during setup
or not.

Fix this by NOT closing the file if we hit this race, but instead wait
until the file is closed after the run.

Fio slows down at the end of a random IO run, when the random
map is used and it gets fuller. This causes slowdowns in
IOPS. This is largely due to the file random map being an
array of bits, and with random access to single bits of the
array at the time, locality is awful. The effect is observable
throughout a run, though, where it gradually gets slower and
slower. It just becomes more apparent at near the end of the
run, where the last 10% are fairly bad. This is even with
doing a bunch of tricks to reduce that cost.

Implement an N-level bitmap, where layer N uses a single bit
to represent 32/64-bits at layer N-1. The number of layers
depends on the number of blocks.

This has slightly higher overhead initially in theory, in
practice it performs about the same. As a bonus, the throughput
remains constant during the run, and even becomes faster
near the end.

Linux offers fallocate() and the FALLOC_FL_KEEP_SIZE option as
an alternative to posix_fallocate(). When FALLOC_FL_KEEP_SIZE is
specified for an falloc request going beyond the end of the file,
the requested blocks get preallocated without changing the apparent
size of the file. This is is a commonly recommended use of fallocate()
for workloads performing append writes.

This patch modifies the fallocate option from a boolean option
to a string option accepting none/posix/keep/0/1. 'keep' is only
made available on systems where FALLOC_FL_KEEP_SIZE is available
(i.e., Linux at this time). If specified, fallocate() is used
with FALLOC_FL_KEEP_SIZE set. 'none' disables pre-allocation while
'posix' uses posix_fallocate(). The default behavior remains unchaned,
i.e., invoking posix_fallocate. The settings '0'/'1' are there to
provide backward compatibility for users who had explicitly set the
boolean option.

- Update HOWTO to note that directio and fallocate don't work with ZFS
on Solaris.

Refactor the Makefile's to add CPPFLAGS and LIBS.
- Add -fno-omit-frame-pointer from Linux Makefile to every platform
- Change undefined $(ALL_CFLAGS) to $(CFLAGS)
- Pass -std=gnu99, without which OS X fails to build.
- Add -D__EXTENSIONS__ on Solaris since some functions we need are
behind it.

- Pull in <limits.h> in fio.c to get PTHREAD_STACK_MIN.
- NetBSD doesn't define PTHREAD_STACK_MIN so set it to 4k in
os-netbsd.h

- If we have posix_fallocate don't error out if it fails during mutex
and malloc operations since it will fail on Solaris with a ZFS
filesystem. As I understand it these aren't performance-critical
operations so do they need to be considered critical?

- Remove fio_unused from os-* files since it's defined in fio.h and we
don't really need it.

- FreeBSD has an idprio command but not the API so don't claim it does.

- OS X doesn't have the timer_* API so emulate it using
setitimer/sigaction.

- NetBSD and Solaris don't support CLOCK_MONOTONIC in timer_create so
remove FIO_HAVE_CLOCK_MONOTONIC from their os-* files.

I've noticed that a change I made a while ago to use fmin/fmax could
cause issues on older OSes - I had a CD with NetBSD 5.0.2 and found
they had only been implemented in 5.1 so I'm not sure if I should
revert it.

Fio still opens and creates all files, just to check the size of them. Add
a specialized IO engine op for getting the size of a file and use that
instead.

This also cleans a lot of things up. Note that the IO engine version is now
bumped to 10, meaning that external engines will have to separate the
file open from the size checking.

Get rid of the semaphore implementation, no need to carry both.
Add different locking modes (exclusive and readwrite) to enable
a wider range of testing. Also combine lockfile and lockfile_batch,
the latter is now a postfix option to the former.

So to enable readers-excluding-writers locking mode with a lock batch
count of 4, you would write:

lockfile=readwrite:4

I ran a test with latest fio using jobfile,

[global]
size=10m
[job1]
ioengine=sync
rw=write
filename=testfile

And second time,
[global]
size=30m --> size increased.
[job1]
ioengine=sync
rw=write
filename=testfile

fio did not extend the file to 30m.

In case of f->file_offset=0, f->io_size equals to f->real_file_size, hence no extend.
Following patch worked for me. But this patch will not handle the case where we have
to extend a file and with offset :(

1. The job file we prepared:
----------offset-----------------
[global]
filename=./temp/HOWTO
nrfiles=1
rw=read
size=8K
offset=16k
bs=1k
thread
loops=10
[offset]
description="Option 'offset' doesn't work."
---------------------------------
Besides, we copied the file HOWTO to the directory ./temp/.
So we thought fio would read 8K text sequentially from the point 16K off
the beginning of HOWTO.

we run fio with gdb to see what was read out after the first io, and we
got this:
---------------------------------
... ...
(gdb) bt
from /lib/tls/i686/cmov/libpthread.so.0
(gdb) x/4w io_u->xfer_buf
0x8073f08: 0x6c626154 0x666f2065 0x6e6f6320
0x746e6574
(gdb)
---------------------------------
The above was performed after the first io finished by td_io_queue.
The contents read out as we can see was the ASCII codes for 'Table of
content', which was right from the beginning of file HOWTO.
That means fio read from the beginning but not the point 16K off the
beginning.Is that right?

2. Reason for the problem:
It seems the offset is saved in td->o.start_offset. But it isn't passed
to f->file_offset.And the setting up of f->io_size doesn't refer to
f->file_offset.

--------------------------------------------------------

And now we can check it with gdb:
--------------------------------------------------------
... ...
(gdb) bt
from /lib/tls/i686/cmov/libpthread.so.0
(gdb) x/4w io_u->xfer_buf
0x8073f08: 0x206b636f 0x7420666f 0x66206568
0x20656c69
(gdb)
---------------------------------------------------------
After the first io, I got '0x206b636f 0x7420666f 0x66206568 0x20656c69'
read out.And they represent the string 'ock of the file '.Then i search
the string in HOWTO and got only one line containing the string:
'norandommap Normally fio will cover every block of the file when doing'
I removed the text following that line in HOWTO, and then I found that
the size of the rest text in HOWTO was 16K, which equaled to the offset
we set in job file.
So I think the option 'offset' does work after the changes.

In fact, I am not sure of the fix, but i do hope it can help.

1. The mission is defined like this:
----------filesize----------------
[global]
directory=./temp
nrfiles=2
rw=randread
filesize=32k
size=96k
thread
[filesize]
description="Filesize less than size."
----------------------------------

This job file caused another non-stop thread, which was asked to read
96K but only provided two files of 32K each. The running information
kept looking like this:
---------------------------------
nonggia@nonggia-desktop:~/fio$ fio --version
fio 1.16.9
nonggia@nonggia-desktop:~/fio$ fio filesize
filesize: (g=0): rw=randread, bs=4K-4K/4K-4K, ioengine=sync, iodepth=1
Starting 1 thread
Jobs: 1 (f=2): [r] [66.7% done] [ 0/ 0 kb/s] [eta 00m:51s]
---------------------------------

2. The reason:
After having covered both the two files, the thread still had 32K to
issued, while there were already no available files on hand.
I agree that it is far from a bug.Maybe it was the job file that we
should blame. It was wrong written from the beginning.But why not make
it more gentle if we can?

3. Fix suggestion:
So what about change it like this?
Just limit the max td->o.size with the total_size that all the files can
provide.
---------------------------------

Some IO engines need special handling for opening and closing
files, and this has complicated the fio filesetup.c file. Instead
have the io engine provide hooks for file open/close. This also
greatly cleans up the flags (we can get rid of SELFOPEN and MMAPIO)
and moves private knowledge into the engines where it belongs.

This potentially destabilizes fio somewhat, so testing is needed.
The new openfiles option that is introduced with this change isn't
verified working yet, hence it isn't documented.

a9defc9abb4a3013335d3aeeb132fd90900cac85 01-Mar-2007 Joel Becker <joel.becker@oracle.com> [PATCH] ioengine flags: Replace FIO_NETIO with real flags that map the
behavior

The FIO_NETIO ioengine flag created two behaviors. First, open_files()
would not open any files - this was handled in engines/net:setup().
Second, init_disk_util() would ignore the files and not try to locate
their disk.

Other engines might want one of these behaviors but not the other. If
an engine opens its own files, it doesn't want open_files() to do anything,
even if the files are eventually disk-based. An engine might want to
prevent init_disk_util() from running.

The FIO_NETIO flag is split into two flags.

FIO_SELFOPEN states that the engine will do its own open(), whether it
is a real open(2) or something internal to the engine.

FIO_DISKLESSIO states that init_disk_util() is should not be run. fio
should treat the engine's files as if they are not part of a disk.

Finally, engines/net.c is changed to use these two flags.
