No, I haven't, but I know its limitations.

OCFS2 (like GFS/GFS2 from sistina/RH) is build on the cluster-FS design
of the 90s.
I'm looking for Cluster-FS which is based on 
+ a system which is inherently dynamic
+ failures in a cluster are the norm, rather than an exception
+ that characters of workloads are constantly shifting over time
+ a system which is inevitably built incrementally
+ a system which is self-managing
= Ceph (RBD + CephFS)
