Happy New Year!
Dave Chinner: I've renumbered the new tests and pushed to github[3] if
you'd like to pull.
This is a (no longer) small patch set against the reflink/dedupe test
cases in xfstests. The first four patches fix errors in the existing
reflink tests, some of which are from Christoph Hellwig.
Patches 5-6 refactor the dmerror code so that we can use it to
simulate transient IO errors, then use this code to test that
unwritten extent conversion does NOT happen after a directio write to
an unwritten extent hits a disk error. Due to a bug in the VFS
directio code, ext4 can disclose stale disk contents if an aio dio
write fails; XFS suffers this problem for any failing dio write to an
unwritten extent. Christoph's kernel patchset titled "vfs/xfs:
directio updates to ease COW handling V2" (and a separate ext4 warning
cleanup) is needed to fix this.
Patches 7-9, 13, 15, 17, 18, 20, 21, and 23 exercise various parts
of the copy on write behavior that are necessary to support shared
blocks. The earlier patches focus on correct CoW behavior in the
presence of IO errors during the copy-write, and the later patches
focus on XFS' new cow-extent-size hint that greatly reduces
fragmentation due to copy on write behavior by encouraging the
allocator to allocate larger extents of replacement blocks.
Patches 10-12 and 14 perform stress testing on reflink and CoW to
check the behaviors when we get close to maximum refcount, when we
specify obnxiously large offsets and lengths, and when we try to
reflink millions of extents at a time.
Patch 16 tests quota accounting behavior when reflink is enabled.
Patch 19 adds a few tests for the XFS reverse mapping btree to ensure
that things like metadump and growfs work correctly.
Patch 22 checks that get_bmapx and fiemap (on XFS) correctly flag
extents as having shared blocks. XFS now follows btrfs and ocfs2
FIEMAP behavior such that if any blocks of a file's extent are shared,
the whole extent is marked shared. This is in contrast to earlier
XFS-only behavior that reported shared and non-shared regions as
separate extents.
If you're going to start using this mess, you probably ought to just
pull from my github trees for kernel[1], xfsprogs[2], xfstests[3],
xfs-docs[4], and man-pages[5]. All tests should pass on XFS. I
tried btrfs this weekend and it failed 166, 175, 182, 266, 271, 272,
278, 281, 297, 298, 304, 333, and 334. ocfs2 (when I jury-rigged it
to run the cp_reflink tests) seemed to have a quota bug and crashes
hard in 284 (but was otherwise fine).
Comments and questions are, as always, welcome.

* [PATCH 01/23] generic/182: this is a dedupe test, check for dedupe

Since this test examines dedupe behavior, the documentation should
say 'dedupe', not 'reflink'. Furthermore, the feature checks must
look for working dedupe functionality, not reflink functionality.

* [PATCH 02/23] xfstests: filter whitespace in 128 and 132

Seems either I have a different lsattr version, or different mount points
cause differences in the golden output. Send the lsattr output through
the whitespaces filter so that it works everywhere.
The lsattr output /does/ change depending on mountpoints. Ick. I'd
actually changed it to the long format output because line length in
the short format changes every time the flags change.

* [PATCH 03/23] xfstests: make _scratch_mkfs_blocksized usable

To: david, darrick.wong; +Cc: linux-btrfs, Christoph Hellwig, fstests, xfs
The default mkfs.xfs options contain -b size=4096, so all tests
using _scratch_mkfs_blocksized won't actually run unless those
options are changed. As we're trying to specificly test 1k
blocks we should always override the default option.

The default mkfs.xfs options contain -b size=4096, so all tests
using _scratch_mkfs_blocksized won't actually run unless those
options are changed. As we're trying to specificly test 1k
blocks we should always override the default option.

* [PATCH 04/23] reflink: remove redundant filesystem checks from the end of the tests

Turns out that check already runs _check_filesystems after each test,
so we don't need to do this at the end of each test.

From: Darrick J. Wong @ 2016-02-09 1:12 UTC (permalink / raw)
To: david, darrick.wong; +Cc: fstests, linux-btrfs, xfs
Turns out that check already runs _check_filesystems after each test,
so we don't need to do this at the end of each test.

* [PATCH 05/23] common/dmerror: add some more dmerror routines

To: david, darrick.wong; +Cc: linux-btrfs, fstests, xfs
Add functions to the dmerror routine so that we can load both the
error table and the linear table. This will help us with EIO testing
of copy-on-write.

Check that we don't expose old disk contents when a directio write to
an unwritten extent fails due to IO errors. This primarily affects
XFS and ext4.

From: Darrick J. Wong @ 2016-02-09 1:12 UTC (permalink / raw)
To: david, darrick.wong; +Cc: fstests, linux-btrfs, xfs
Check that we don't expose old disk contents when a directio write to
an unwritten extent fails due to IO errors. This primarily affects
XFS and ext4.

Done.
Should the CoW tests be in 'rw' too? They're testing IO, but otoh they
(most probably) require shared blocks to have much of a point.

* [PATCH 07/23] reflink: test intersecting CoW and falloc/fpunch/fzero/fcollapse/finsert/ftrunc

Ensure that we correctly handle a CoW operation immediately followed
by a truncate, falloc, fpunch, fzero, fcollapse, and finsert operation
in the middle of the CoW'd region before any flush can occur.

To: david, darrick.wong; +Cc: fstests, linux-btrfs, xfs
Ensure that we correctly handle a CoW operation immediately followed
by a truncate, falloc, fpunch, fzero, fcollapse, and finsert operation
in the middle of the CoW'd region before any flush can occur.

* [PATCH 08/23] reflink: test CoW behavior with IO errors
2016-02-09 1:11 ` Darrick J. Wong
@ 2016-02-09 1:12 ` Darrick J. Wong

From: Darrick J. Wong @ 2016-02-09 1:12 UTC (permalink / raw)
To: david, darrick.wong; +Cc: linux-btrfs, fstests, xfs
Test various scenarios (with dm-flakey) where we simulate write
failures during CoW, to see if the FS can get through it without
blowing up or corrupting data. Plumb in a FS-generic method to
sort out repairing filesystems after they get hit by IO errors.

From: Darrick J. Wong @ 2016-02-09 1:12 UTC (permalink / raw)
To: david, darrick.wong; +Cc: fstests, linux-btrfs, xfs
Test various scenarios (with dm-flakey) where we simulate write
failures during CoW, to see if the FS can get through it without
blowing up or corrupting data. Plumb in a FS-generic method to
sort out repairing filesystems after they get hit by IO errors.

and shrinking the refcount btree works and a second one to check
what happens when we hit maximum refcount.

I suspect we need a _require rule for checking that something in
the test src directory has been built.

This is what _require_scratch_nocheck avoids.
i.e. do this instead:
_require_scratch_nocheck
.....
"$XFS_REPAIR_PROG" -o force_geometry -n "$SCRATCH_DEV" >> "$seqres.full" 2>&1
status=$?
exit
Also, we really don't need the quotes around these global
variables. They are just noise and lots of stuff will break if
those variables are set to something that requires them to be
quoted.
Cheers,
Dave.

Crapola, we also need punch-alternating, which doesn't appear until the next
patch. Guess I'll go move it out of the next patch (or swap the order of
these two I guess.)
I added _require_test_program() which complains if src/$1 isn't built.

* [PATCH 11/23] reflink: ensure that we can handle reflinking a lot of extents

To: david, darrick.wong; +Cc: linux-btrfs, Christoph Hellwig, fstests, xfs
Update the existing stress tests to ensure that we can handle
reflinking the same block a million times, and that we can handle
reflinking million different extents. Add a couple of tests to ensure
that we can ^C and SIGKILL our way out of long-running reflinks.
v2: Don't run the signal tests on NFS, as we cannot interrupt NFS
clone operations.

^ permalink raw reply related [flat|nested] 88+ messages in thread* [PATCH 11/23] reflink: ensure that we can handle reflinking a lot of extents
@ 2016-02-09 1:12 ` Darrick J. Wong
0 siblings, 0 replies; 88+ messages in thread
From: Darrick J. Wong @ 2016-02-09 1:12 UTC (permalink / raw)
To: david, darrick.wong; +Cc: fstests, Christoph Hellwig, linux-btrfs, xfs
Update the existing stress tests to ensure that we can handle
reflinking the same block a million times, and that we can handle
reflinking million different extents. Add a couple of tests to ensure
that we can ^C and SIGKILL our way out of long-running reflinks.
v2: Don't run the signal tests on NFS, as we cannot interrupt NFS
clone operations.

I wasn't sure how to handle this -- I could just keep the patch at the head of
my stack (unreleased) until xfsprogs pulls in the appropriate libxfs pieces?
So long as we're not dead certain of the final format of the rmapbt and
refcountbt, there's probably not a lot of value in putting this in (yet).

Well, I'm more concerned about running on older/current distros that
don't have support for them in userspace. My brain is mush right
now, so I don't have any brilliant ideas (hence the question, rather
than also presenting a posible solution). I'll have a think; maybe
we can make use of the configurable .out file code we have now?
Cheers,
Dave.

* [PATCH 13/23] xfs: test fragmentation characteristics of copy-on-write

Perform copy-on-writes at random offsets to stress the CoW allocation
system. Assess the effectiveness of the extent size hint at
combatting fragmentation via unshare, a rewrite, and no-op after the
random writes.

@ 2016-02-09 1:13 ` Darrick J. Wong

From: Darrick J. Wong @ 2016-02-09 1:13 UTC (permalink / raw)
To: david, darrick.wong; +Cc: fstests, linux-btrfs, xfs
Perform copy-on-writes at random offsets to stress the CoW allocation
system. Assess the effectiveness of the extent size hint at
combatting fragmentation via unshare, a rewrite, and no-op after the
random writes.

Now that I've noticed it, a few tests have this line commented out.
Probably should remove the tmp files, at least.

Again, somthing that is repeated - we just mkfs'd the scratch
device, so the $testdir is guaranteed not to exist...

I've also noticed this in a lot of tests - the scratch device will
be unmounted by the harness, so I don't think this is necessary....

Why not:
_require_fs_space $space_needed
At minimum, it seems to be a repeated hunk of code, so it shoul dbe
factored.

For this sort of thing, just dump the extent size value to the
golden output. i.e.
echo "Check extsz and cowextsz settings on zero byte file"
$XFS_IO_PROG -c extsize $testdir/file1
$XFS_IO_PROG -c cowextsize $testdir/file1
is all that is needed. that way if it fails, we see what value it
had instead of the expected 1MB. This also makes the test much less
verbose and easier to read

Same with all these - just grep the output for the line you want,
and the golden output matching does everything else. e.g. the flag
check simply becomes:
$XFS_IO_PROG -c "stat" $testdir/file3 | grep 'fsxattr.xflags'
Again, this tells us what the wrong flags are if it fails...
There are quite a few bits of these tests where the same thing
applies....

Now that I've noticed it, a few tests have this line commented out.
Probably should remove the tmp files, at least.

Again, somthing that is repeated - we just mkfs'd the scratch
device, so the $testdir is guaranteed not to exist...

I've also noticed this in a lot of tests - the scratch device will
be unmounted by the harness, so I don't think this is necessary....

Why not:
_require_fs_space $space_needed
At minimum, it seems to be a repeated hunk of code, so it shoul dbe
factored.

For this sort of thing, just dump the extent size value to the
golden output. i.e.
echo "Check extsz and cowextsz settings on zero byte file"
$XFS_IO_PROG -c extsize $testdir/file1
$XFS_IO_PROG -c cowextsize $testdir/file1
is all that is needed. that way if it fails, we see what value it
had instead of the expected 1MB. This also makes the test much less
verbose and easier to read

Same with all these - just grep the output for the line you want,
and the golden output matching does everything else. e.g. the flag
check simply becomes:
$XFS_IO_PROG -c "stat" $testdir/file3 | grep 'fsxattr.xflags'
Again, this tells us what the wrong flags are if it fails...
There are quite a few bits of these tests where the same thing
applies....

I've done that to the new tests, will do to the existing ones.

Done. It'll probably break whenever we add new flags, but that can be fixed.

Ensure that we can pass absurdly enormous offsets and lengths to
reflink/dedupe and it'll survive.
v2: Ask for dedupe in the dedupe test.

off=$((blksz * nr / 4))

Ok, I just realised what was bugging me about these loops: "f" is
not a typical loop iterator for a count. Normally we'd use "i" for
these....

I wouldn't use _fail like this, echo is sufficient to cause the test
to fail.

offset = block size times block size?
I think some better names might be needed...

Are you testing repair here? If so, why doesn't failure matter.
If not, why do it? Or is _require_scratch_nocheck all that is needed
here?

offset = block size times block size?
I think some better names might be needed...

Uggghhh.... so xfs_repair dumps its regular output to stderr, so the "2>&1"
pushes the output to $seqres.full.
The return codes from xfs_repair seem to be:
0: fs is ok now
1: fs is probably broken
2: log needs to be replayed
The return codes from fsck seem to be:
0: no errors found
1: errors fixed
2: errors fixed, reboot required
(etc)
So I guess the way out is to provide a better wrapper to the repair tools
so that _repair_scratch_fs always returns 0 for "fs should be ok now" and
nonzero otherwise:
_repair_scratch_fs()
{
case $FSTYP in
xfs)
_scratch_xfs_repair "$@" 2>&1
res=$?
if [ "$res" -eq 2 ]; then
echo "xfs_repair returns $res; replay log?"
_scratch_mount
res=$?
if [ "$res" -gt 0 ]; then
echo "mount returns $res; zap log?"
_scratch_xfs_repair -L 2>&1
echo "log zap returns $?"
else
umount "$SCRATCH_MNT"
fi
_scratch_xfs_repair "$@" 2>&1
res=$?
fi
test $res -ne 0 && >&2 echo "xfs_repair failed, err=$res"
return $res
;;
*)
# Let's hope fsck -y suffices...
fsck -t $FSTYP -y $SCRATCH_DEV 2>&1
res=$?
case $res in
0|1|2)
res=0

Yes. Is now "bufnr" and bufsize=$((blksz * bufnr)).

Make sure that xfs_getbmapx behaves properly w.r.t. shared extents
and CoW fork reporting.

To: david, darrick.wong; +Cc: linux-btrfs, fstests, xfs
Set up an impossibly small filesystem and try to reflink and rewrite a
file on it to see what happens when we ENOSPC. Basically
generic/16[67] but with a constrained fs size.

Set up an impossibly small filesystem and try to reflink and rewrite a
file on it to see what happens when we ENOSPC. Basically
generic/16[67] but with a constrained fs size.

Can you include the commit ID I should see at the head of the
tree so I can confirm I'm pulling the right branch?
BTW, git doesn't like this:
https://github.com/djwong/xfstests/tree/for-dave
What git really wants is the tree url with a separate branch name
like so:

This may change - xfs_bmap doesn't combine extents in it's output
even if they are adjacent. For debugging purposes (which is what
xfs_bmap/fiemap is for), it's much better to be able to see the
exact extent layout and block sharing.
I suspect the solution of least surprise is to make fiemap behave
like the other filesystems, and make xfs_bmap behave in a manner
that is useful to us.... :P

Fun fun fun. I'll look through the patchs, and if there's nothing
major I'll pull it in once I get a commit ID from you.

Heh, surprisingly, I've never ever sent a pull request to anyone, anywhere. :)

Hehe. Well... FIEMAP now /does/ act like the other filesystems.
But perhaps we can do better with getbmapx and show the exact

Heh, surprisingly, I've never ever sent a pull request to anyone, anywhere. :)
