GFS2 remains as a technology preview. Installing gfs-utils pulls in gfs2-utils, which is not supported; so is gfs-utils supported or unsupported?

For RHEL5.1 and 5.2, gfs and gfs2 use the same cluster infrastructure. That's because they share a common lock protocol kernel module, lock_dlm which calls dlm. The specific components of that infrastructure (i.e. lock_dlm and dlm itself) should, in my opinion, be supported. The part that isn't supported is the gfs2 file system kernel module. For future releases (hopefully 5.3) the GFS and GFS2 infrastructures are being separated out so this should not be an issue.
This won't be an issue in 5.3 with the release of the bugs listed here: https://bugzilla.redhat.com/show_bug.cgi?id=447748#c12
