On our cluster, 12 files were reported as corrupt by fsck even though the replicas on the datanodes were healthy.
Turns out that all the replicas (12 files x 3 replicas per file) were reported corrupt from one node.
Surprisingly, these files were still readable/accessible from dfsclient (-get/-cat) without any problems.
