It seems to be a known failure. ext4/004, along with various other tests, is excluded by https://github.com/tytso/xfstests-bld/blob/master/test-appliance/files/root/fs/ext4/cfg/encrypt.exclude as follows: ext4/004 // dump/restore doesn't handle quotas I'm not sure why the comment mentions quotas. It probably should say "encryption", not "quotas". Either way, the exclusion logic in xfstests-bld really should be incorporated directly into xfstests, e.g. by using _exclude_test_mount_option "test_dummy_encryption". This seems to be a wider issue. Effectively, ext4's exclusion lists for xfstests are being maintained outside of xfstests itself. - Eric
