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.
