Yes, that's known issue. generic/04[456] were originally XFS specific tests, and they have have assumptions about the implementation of the underlying file system. We have a few of those at the moment in kvm-xfstests/gce-xfstests's exclude file: https://git.kernel.org/cgit/fs/ext2/xfstests-bld.git/tree/kvm-xfstests /test-appliance/files/root/fs/ext4/exclude # generic/042 and generic/392 are failing because ext4 forces the # resolution of all delayed allocation writes before allowing the # punch operation to proceed. We probably want to see if we can avoid # this for the future, but what ext4 is doing is legal, so just skip # the test for now generic/042 generic/392 # generic/04[456] tests how truncate and delayed allocation works # ext4 uses the data=ordered to avoid exposing stale data, and # so it uses a different mechanism than xfs. So these tests will fail generic/044 generic/045 generic/046 # generic/223 tests file alignment, which works on ext4 only by # accident because we're not RAID stripe aware yet, and works at all # because we have bias towards aligning on power-of-two block numbers. # It is a flaky test for some configurations, so skip it. generic/223 # ext4/304 fails for all configurations, and this appears to be at # test or fio bug. # ext4/304" --- So I think these failures are false positive results for ext4. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1704730 Title: xfstest fails with corrupt file /mnt/scratch/1 - non-zero size but no extents ( ext4 ) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1704730/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
