Hi, After Brian fixed a panic bug reproduced by generic/388: xfs: release bli from transaction properly on fs shutdown xfs: remove bli from AIL before release on transaction abort I tried to run g/388 again. Then I found a corruption [1] and lots of dmesg error output [2]. I tested on kernel-4.14.0-rc2, and I can reproduce this bug on other architectures with different block size (512/1024/2048/4096) by run generic/388 many times (I reproduced it within 100 times). You can find the corrupted XFS metadump and dmesg from: https://drive.google.com/open?id=0B5dFDeCXGOPXU0ROMlNHN0dHZ00 Thanks, Zorro [1] generic/388 97s ... 122s _check_xfs_filesystem: filesystem on /dev/mapper/rhelp_hp--dl380pg8--01-scratchdev is inconsistent (c) (see /root/git/xfstests-dev/results//generic/388.full for details) _check_xfs_filesystem: filesystem on /dev/mapper/rhelp_hp--dl380pg8--01-scratchdev is inconsistent (r) (see /root/git/xfstests-dev/results//generic/388.full for details) _check_dmesg: something found in dmesg (see /root/git/xfstests-dev/results//generic/388.dmesg) Ran: generic/388 Failures: generic/388 Failed 1 of 1 tests # xfs_repair -n $SCRATCH_DEV Phase 1 - find and verify superblock... - reporting progress in intervals of 15 minutes Phase 2 - using internal log - zero log... - scan filesystem freespace and inode maps... - 07:25:39: scanning filesystem freespace - 16 of 16 allocation groups done - found root inode chunk Phase 3 - for each AG... - scan (but don't clear) agi unlinked lists... - 07:25:39: scanning agi unlinked lists - 16 of 16 allocation groups done - process known inodes and perform inode discovery... - agno = 0 - agno = 15 mismatch between format (2) and size (0) in symlink ino 1541 bad data fork in symlink 1541 would have cleared inode 1541 - agno = 1 - agno = 2 - agno = 3 - agno = 4 - agno = 5 - agno = 6 - agno = 7 - agno = 8 - agno = 9 - agno = 10 - agno = 11 - agno = 12 - agno = 13 - agno = 14 - 07:25:39: process known inodes and inode discovery - 2624 of 2624 inodes done - process newly discovered inodes... - 07:25:39: process newly discovered inodes - 16 of 16 allocation groups done Phase 4 - check for duplicate blocks... - setting up duplicate extent list... - 07:25:39: setting up duplicate extent list - 16 of 16 allocation groups done - check for inodes claiming duplicate blocks... - agno = 0 - agno = 2 - agno = 1 - agno = 3 - agno = 5 - agno = 7 - agno = 9 - agno = 4 - agno = 10 - agno = 13 - agno = 8 - agno = 15 mismatch between format (2) and size (0) in symlink ino 1541 bad data fork in symlink 1541 would have cleared inode 1541 - agno = 11 - agno = 14 - agno = 12 - agno = 6 - 07:25:39: check for inodes claiming duplicate blocks - 2624 of 2624 inodes done No modify flag set, skipping phase 5 Phase 6 - check inode connectivity... - traversing filesystem ... - traversal finished ... - moving disconnected inodes to lost+found ...
