Hi all, The master branch of the xfstests repository at: git://git.kernel.org/pub/scm/fs/xfs/xfstests-dev.git have just been updated. This update pulls in the dm-log-writes patches and tests from Amir Goldstein and Josef Bacik, many thanks to Amir and Josef!! I quoted the words from Amir's cover letters to describe this work (but with the test numbers changed to reflect current status): " I've collected these patches that have been sitting in Josef Bacik's tree for a few years and kicked them a bit into shape. The dm-log-writes target has been merged to kernel v4.1, see: https://github.com/torvalds/linux/blob/master/Documentation/device-mapper/log-writes.txt I've added some debugging options for running fsx and replay-log, which I used to analyze the crash consistency bugs uncovered by the tests. The original fsx crash consistency test (generic/455) is failing sometimes on kernel v4.13 for ext4, btrfs and xfs. A fix for xfs is queued for v4.14, I think there is a fix by Josef for btrfs queued for v4.14 as well. A 'quick' and reliable regression test (generic/456) was created for the ext4 issue. I created another crash consistency test which runs fsx on cloned files (generic/457). This test is failing check fs sometimes on kernel v4.13, at the end of the test, but this is not related to crash consistency. There is a fix is the works for v4.14. A 'quick' and reliable regression test (generic/458) was created for this issue. The new 'clones crash' test (generic/457) is also failing sometimes on xfs_repair errors like: "fatal error -- illegal state 13 in block map 147", on crash points, but I havn't been able to narrow down the issue yet. " To run these new crash consistency tests, you need to enable CONFIG_DM_LOG_WRITES kernel configuration and assign a block device to a new LOGWRITES_DEV variable, which is used by the dm-log-writes target to record the write log entries. Also, there's another new overlay test added, which Amir helped on patch review as well. Thanks again to Amir! New failures I've noticed in this update, all tested against 4.13 kernel: - generic/455 fails sometimes on btrfs/ext4/xfs - generic/456 fails always on ext4 - generic/457 fails sometimes on xfs with reflink - generic/458 fails always on xfs with reflink - overlay/038 tests constant d_ino and fails Thanks, Eryu The new head of the master branch is commit: b309f083516f generic: renumber tests after merge New commits: Amir Goldstein (13): [3582f7b1bf00] fsx: add support for integrity check with dm-log-writes target [bd918dff012b] fsx: add optional logid prefix to log messages [3f742550dfed] fsx: add support for recording operations to a file [90d0b3e166d8] fsx: add support for writing constant instead of random data [2a15cabaf6a2] fsx: add support for keeping existing file [b1e2e6b0279e] log-writes: add replay-log program to replay dm-log-writes target [9892f3155f63] replay-log: add validations for corrupt log entries [b65b808ee3df] replay-log: add support for replaying ops in target device sector range [520cddd8d0dd] fstests: add support for working with dm-log-writes target [dd0b40b620e8] generic: crash consistency fsx test using dm-log-writes [88ef97bf667e] generic: regression test for ext4 crash consistency bug [cc2d3d6f5f2a] generic: crash consistency fsx test for cloned files [5f9296904a95] generic: regression test for xfs leftover CoW extent error Chandan Rajendra (1): [72da031cc1b1] overlay: Test constant d_ino feature Eryu Guan (1): [b309f083516f] generic: renumber tests after merge Code Diffstat: .gitignore | 1 + README | 2 + common/dmlogwrites | 90 +++++++++ doc/auxiliary-programs.txt | 8 + doc/requirement-checking.txt | 20 ++ ltp/fsx.c | 273 ++++++++++++++++++++------ src/Makefile | 2 +- src/log-writes/Makefile | 23 +++ src/log-writes/SOURCE | 6 + src/log-writes/log-writes.c | 458 +++++++++++++++++++++++++++++++++++++++++++ src/log-writes/log-writes.h | 86 ++++++++ src/log-writes/replay-log.c | 389 ++++++++++++++++++++++++++++++++++++ tests/generic/455 | 132 +++++++++++++ tests/generic/455.out | 2 + tests/generic/456 | 80 ++++++++ tests/generic/456.out | 2 + tests/generic/457 | 135 +++++++++++++ tests/generic/457.out | 2 + tests/generic/458 | 74 +++++++ tests/generic/458.out | 2 + tests/generic/group | 4 + tests/overlay/038 | 196 ++++++++++++++++++ tests/overlay/038.out | 2 + tests/overlay/group | 1 + 24 files changed, 1929 insertions(+), 61 deletions(-) -- Eryu Guan eguan@xxxxxxxxxx
