Need to re replicate

[Ananth T. Sarathy]

One of our datanodes went bye bye. We added a bunch more data nodes, but
when I do a fsck i get a report that a bunch of files are only replicated on
2 server, which makes sense, because we had 3, and lost one. Now that we
have 6 more, is there anything i need to do replicate the those files are
will the cluster fix itself?
