Quoting from Josef's commit message: The test just runs some ops and exits, then finds all of the good buffers in the directory we provided and: - replays up to the mark given - mounts the file system and compares the md5sum - unmounts and fsck's to check for metadata integrity dm-log-writes will pretend to do discard and the replay-log tool will replay it properly depending on the underlying device, either by writing 0's or actually calling the discard ioctl, so I've enabled discard in the test for maximum fun. [Amir:] - Removed unneeded _test_falloc_support dynamic FSX_OPTS - Fold repetitions into for loops - Added place holders for using constant random seeds - Add pre umount checkpint - Add test to new 'replay' group - Address review comments by Eryu Guan Cc: Josef Bacik Signed-off-by: Amir Goldstein --- tests/generic/500 | 138 ++++++++++++++++++++++++++++++++++++++++++++++++++ tests/generic/500.out | 2 + tests/generic/group | 1 + 3 files changed, 141 insertions(+) create mode 100755 tests/generic/500 create mode 100644 tests/generic/500.out diff --git a/tests/generic/500 b/tests/generic/500 new file mode 100755 index 0000000..fd4d6ec --- /dev/null +++ b/tests/generic/500 @@ -0,0 +1,138 @@ +#! /bin/bash +# FS QA Test No. 500 +# +# Run fsx with log writes to verify power fail safeness. +# +#----------------------------------------------------------------------- +# Copyright (c) 2015 Facebook.
