[Bug 1696102] Re: xfs/073 test fails with Metadata corruption detected on xfs file system (xfsprogs)

Fri Sep 8 07:15:32 UTC 2017

[21:30] <bdmurray> Could you update the test case with the setup you
configured on diamond? I just used the environment you had configured so
I'm not convinced what I tried at home was good.

Helping where I can :-)

  Steps to reproduce:
  ----------------------------------------
  1. Create a loop device with xfs filesystem
  2. git clone git://git.kernel.org/pub/scm/fs/xfs/xfstests-dev.git; cd xfstests-dev
  3. make
  4. Create a local.conf for running with created loop device
  5.. Run xfstests-dev test  : ./check tests/xfs/073

  Full log is attached.

  Create loop device:
  # mkdir /mnt/loop-device /mnt/test /mnt/scratch

  # for i in $(seq 0 1); do fallocate -o 0 -l 5GiB /mnt/loop-device/file-$i.img; done
  # for i in $(seq 0 1); do losetup /dev/loop$i /mnt/loop-device/file-$i.img; done

  Create File system:
  # for i in $(seq 0 1); do mkfs.ext4 -F /dev/loop$i; done

  # cat local.config
  export TEST_DEV=/dev/loop0
  export TEST_DIR=/mnt/test
  export SCRATCH_DEV=/dev/loop1
  export SCRATCH_MNT=/mnt/scratch
