On my test infrastructure (using gce-xfstests, which uses 5gig test and scratch partitions using PD-SSD as the device, 2CPU's, with 7.5 GB of memory), it's failing 70% of the time in the 1k and orphan_file_1k case. Looking through my notes, that's a known failure: generic/476 1k Run an all-writes fsstress run with multiple threads to shake out bugs in the write path. 50% of the time. fsck complaining corrupted file system block bitmap differences all negative. Possible cause: races loading adjacent block bitmaps in a single 4k page, leading to bitmap updates getting lost? Eric Whitney reports that it's a punch hole bug, where we are leaking a block or a cluster (in bigalloc); with fixed seed he can repro reliably at 100%. - Ted TESTRUNID: tytso-20210825172314 KERNEL: kernel 5.14.0-rc2-xfstests-00019-g3e5533948c16 #326 SMP Mon Aug 23 22:27:25 EDT 2021 x86_64 CMDLINE: --update-files -c 1k -C 10 generic/476 CPUS: 2 MEM: 7680 ext4/1k: 10 tests, 7 failures, 3399 seconds generic/476 Failed 327s generic/476 Failed 348s generic/476 Failed 344s generic/476 Pass 343s generic/476 Pass 335s generic/476 Failed 348s generic/476 Failed 341s generic/476 Failed 335s generic/476 Failed 345s generic/476 Pass 333s Totals: 10 tests, 0 skipped, 7 failures, 0 errors, 3399s FSTESTIMG: gce-xfstests/xfstests-202108232144 FSTESTPRJ: gce-xfstests FSTESTVER: blktests 62ec9d6 (Tue, 1 Jun 2021 10:08:38 -0700) FSTESTVER: e2fsprogs v1.46.4-5-g4cda2545-orphan_file (Sun, 22 Aug 2021 10:07:15 -0400) FSTESTVER: fio fio-3.27 (Wed, 26 May 2021 10:10:32 -0600) FSTESTVER: fsverity v1.4 (Mon, 14 Jun 2021 16:14:52 -0700) FSTESTVER: ima-evm-utils v1.3.2 (Wed, 28 Oct 2020 13:18:08 -0400) FSTESTVER: nvme-cli v1.14-61-gf729e93 (Fri, 25 Jun 2021 10:21:17 -0600) FSTESTVER: quota v4.05-40-g25f16b1 (Tue, 16 Mar 2021 17:57:19 +0100) FSTESTVER: util-linux v2.37 (Tue, 1 Jun 2021 09:52:10 +0200) FSTESTVER: xfsprogs v5.12.0 (Fri, 21 May 2021 15:53:24 -0400) FSTESTVER: xfstests-bld 779b6a0 (Mon, 23 Aug 2021 21:29:52 -0400) FSTESTVER: xfstests linux-v3.8-3295-gddc09fff (Mon, 23 Aug 2021 20:54:57 -0400) FSTESTCFG: 1k FSTESTSET: generic/476 FSTESTOPT: count 10 aex GCE ID: 2585249240830380583
