When users of the first version of the Oracle Cluster FileSystem (OCFS) began demanding the sort of features found in a normal native filesystem, (a real general purpose cluster filesystem), OCFS2 was the result, according to Wim Coekaerts's explanatory post on the history of the solution.

OCFS2 today, in the mainline kernel, is pretty much feature complete in terms of integration with every filesystem feature Linux offers, Coekaerts avers, and it is still actively maintained with Joel Becker being the primary maintainer.
