No. They're similar, but the main difference at here: + # Exceed the soft quota limit a bit at first + su $qa_user -c "$XFS_IO_PROG -f -t -c 'pwrite 0 2m' -c fsync ${file}.0" >>$seqres.full 2>&1 + # Write more data more times under soft quota limit exhausted condition, + # but not reach hard limit.

Thanks, Zorro [1] 2022-04-14 16:49 < zlang> https://lore.kernel.org/fstests/161526483668.1214319.17667836667890283825.stgit@magnolia/ 2022-04-14 16:50 < zlang> djwong: About xfs/144 ^^, are we going to remove it, or change it to cover old quota warning behavior (without warn counter)? 2022-04-14 17:04 < zlang> Just due to notice your discussion in https://lore.kernel.org/linux-xfs/20220314180914.GN8224@magnolia/, and our downstream testing fails on xfs/144. So ask your plan :) 2022-04-14 22:53 < djwong> zlang: catherine is working on a patch to kill the warning counter limit feature entirely, since it's been largely busted for 20 years 2022-04-14 22:53 < djwong> so with that xfs/144 can be removed entirely 2022-04-14 23:11 < zlang> djwong: I'm wondering one thing, after the "the warning counter" feature being merged, why there's not any xfstests quota related cases fail on it 2022-04-14 23:12 < zlang> That might mean we miss some testing coverage 2022-04-14 23:13 < zlang> Maybe some code branches we never through, likes the place where you add "res->warnings++" :) 2022-04-14 23:15 < zlang> Even for us, we get the complaint from customers, before we find this behavior change by our testing 2022-04-14 23:19 < sandeen> djwong, if catherine would like to send the one-liner ASAP to make the next kernel, that would be fantastic, with a followup to remove the rest of the code ;) 2022-04-14 23:19 < zlang> So I'd like to change xfs/144 to cover old quota warning expected behavior, What do you think? 2022-04-14 23:19 < sandeen> zlang, what old quota warning expected behavior? 2022-04-14 23:21 < sandeen> to be clear, there are two notions of "warnings" here. thre is a netlink interface which can send the user over-quota notices. That has been there a long time, and exists for vfs quota too. But that is not really related to the quota warning counter/limit code, which is unique to xfs, and broken. 2022-04-14 23:22 < zlang> sandeen: https://paste.centos.org/view/c66654c0 2022-04-14 23:22 < zlang> old behavior means this testing won't fail ^^ 2022-04-14 23:23 < zlang> Before, we always write one single file until exceed soft limit 2022-04-14 23:23 < zlang> We never tested write several small files until exceed soft limit 2022-04-14 23:23 < sandeen> if I am reading the test correctly, you have a soft limit of 2 megs and a hard limit of 500 megs. And you have a grace period of 6 days. 2022-04-14 23:24 < sandeen> Then you write 202 megs immediately. 2022-04-14 23:24 < zlang> Yes, create ~100 2M file 2022-04-14 23:24 < sandeen> all of this happens before the 6 days grace period expires, so all writes should succeed. 2022-04-14 23:25 < zlang> Yes 2022-04-14 23:25 < zlang> Before, we generally write one single 200M file to test the soft limit 2022-04-14 23:25 < sandeen> with the quota warning limit patch, they do not succeed. but that, IMHO, was a bug which needs to be fixed. 2022-04-14 23:25 < sandeen> oh I see. 2022-04-14 23:26 < sandeen> so you're suggesting that another test which exceeds soft quota with many writes is a good idea, and would have caught the quota warning /limit/ problem - right? 2022-04-14 23:26 < sandeen> that sounds reasonable to me 2022-04-14 23:33 < zlang> Due to the warning counter feature broke our customers' environment at first, but our regression test pass as usual. 2022-04-14 23:36 < zlang> So I hope a test can detect this behavior change, even if we really like to change that in one day, we can remove/change this test then. 2022-04-14 23:43 < zlang> And don't worry, I'll write that test after you revert that feature, just ask your plans :) > > --D > > > Signed-off-by: Zorro Lang <zlang@redhat.com> > > --- > > tests/generic/690 | 125 ++++++++++++++++++++++++++++++++++++++++++ > > tests/generic/690.out | 2 + > > 2 files changed, 127 insertions(+) > > create mode 100755 tests/generic/690 > > create mode 100644 tests/generic/690.out > > > > diff --git a/tests/generic/690 b/tests/generic/690 > > new file mode 100755 > > index 00000000..b1d055dc > > --- /dev/null > > +++ b/tests/generic/690 > > @@ -0,0 +1,125 @@ > > +#! /bin/bash > > +# SPDX-License-Identifier: GPL-2.0 > > +# Copyright (c) 2022 Red Hat Inc.

So ask your plan :) > 2022-04-14 22:53 < djwong> zlang: catherine is working on a patch to kill the warning counter limit feature entirely, since it's been largely busted for 20 years > 2022-04-14 22:53 < djwong> so with that xfs/144 can be removed entirely > 2022-04-14 23:11 < zlang> djwong: I'm wondering one thing, after the "the warning counter" feature being merged, why there's not any xfstests quota related cases fail on it > 2022-04-14 23:12 < zlang> That might mean we miss some testing coverage > 2022-04-14 23:13 < zlang> Maybe some code branches we never through, likes the place where you add "res->warnings++" :) > 2022-04-14 23:15 < zlang> Even for us, we get the complaint from customers, before we find this behavior change by our testing > 2022-04-14 23:19 < sandeen> djwong, if catherine would like to send the one-liner ASAP to make the next kernel, that would be fantastic, with a followup to remove the rest of the code ;) > 2022-04-14 23:19 < zlang> So I'd like to change xfs/144 to cover old quota warning expected behavior, What do you think? > 2022-04-14 23:19 < sandeen> zlang, what old quota warning expected behavior? > 2022-04-14 23:21 < sandeen> to be clear, there are two notions of "warnings" here. thre is a netlink interface which can send the user over-quota notices. That has been there a long time, and exists for vfs quota too. But that is not really related to the quota warning counter/limit code, which is unique to xfs, and broken. > 2022-04-14 23:22 < zlang> sandeen: https://paste.centos.org/view/c66654c0 > 2022-04-14 23:22 < zlang> old behavior means this testing won't fail ^^ > 2022-04-14 23:23 < zlang> Before, we always write one single file until exceed soft limit > 2022-04-14 23:23 < zlang> We never tested write several small files until exceed soft limit > 2022-04-14 23:23 < sandeen> if I am reading the test correctly, you have a soft limit of 2 megs and a hard limit of 500 megs. And you have a grace period of 6 days. > 2022-04-14 23:24 < sandeen> Then you write 202 megs immediately. > 2022-04-14 23:24 < zlang> Yes, create ~100 2M file > 2022-04-14 23:24 < sandeen> all of this happens before the 6 days grace period expires, so all writes should succeed. > 2022-04-14 23:25 < zlang> Yes > 2022-04-14 23:25 < zlang> Before, we generally write one single 200M file to test the soft limit > 2022-04-14 23:25 < sandeen> with the quota warning limit patch, they do not succeed. but that, IMHO, was a bug which needs to be fixed. > 2022-04-14 23:25 < sandeen> oh I see. > 2022-04-14 23:26 < sandeen> so you're suggesting that another test which exceeds soft quota with many writes is a good idea, and would have caught the quota warning /limit/ problem - right? > 2022-04-14 23:26 < sandeen> that sounds reasonable to me > 2022-04-14 23:33 < zlang> Due to the warning counter feature broke our customers' environment at first, but our regression test pass as usual. > 2022-04-14 23:36 < zlang> So I hope a test can detect this behavior change, even if we really like to change that in one day, we can remove/change this test then. > 2022-04-14 23:43 < zlang> And don't worry, I'll write that test after you revert that feature, just ask your plans :) > > > > > --D > > > > > Signed-off-by: Zorro Lang <zlang@redhat.com> > > > --- > > > tests/generic/690 | 125 ++++++++++++++++++++++++++++++++++++++++++ > > > tests/generic/690.out | 2 + > > > 2 files changed, 127 insertions(+) > > > create mode 100755 tests/generic/690 > > > create mode 100644 tests/generic/690.out > > > > > > diff --git a/tests/generic/690 b/tests/generic/690 > > > new file mode 100755 > > > index 00000000..b1d055dc > > > --- /dev/null > > > +++ b/tests/generic/690 > > > @@ -0,0 +1,125 @@ > > > +#! /bin/bash > > > +# SPDX-License-Identifier: GPL-2.0 > > > +# Copyright (c) 2022 Red Hat Inc.

And then we try to write 101M to a file? Maybe 102M, due to the first file is 2M, to exceed soft limit(1M), then later 100*1M files.
