Both ext4 and XFS demonstrated good resilience, but XFS leaves empty files in directories where corrupt files were, while ext4's fsck moves them to lost+found without a trace. When that happens, Swift's auditors cannot know that something was amiss and the replication is not triggered (because hash lists are only updated by auditors). Mr. You Yamagata worked on a patch to address this problem, but did not complete it.
